I'm very new to Dutch scapes when it comes to setting one up but have been reading up and gathering info for a while. Would be interested in sharing ideas and learning techniques especially when in comes to placement and trimming.

Anyone interested in Dutch style scaping read the following:
Article by Vin
Summary:
SECTION ONE:
GETTING STARTED
1. MUST HAVE STRONG
CONTRAST BETWEEN GROUPS: You need dramatic contrasts.
Always think of contrast in leaf
shape, size, texture, brightness,
and height.
one plant with BIG
leaves. Maybe an Echinodorus
or Aponogeton or Barclaya,
Nymphaea, Lagenandra, Anubias,
or Nuphar. Even a stem plant like
Hygrophila corymbosa.
2. LEAVE ROOM FOR A CLEAR
DISTINCTION BETWEEN
GROUPS OF PLANTS. This is
tied to proper trimming and floor
layout
3. HEIGHT VARIATION IS
IMPORTANT

6. ONE SPECIES PER 10 CM/4
IN. OR THREE SPECIES PER
FOOT OF TANK LENGTH.
Too many species makes the tank
busy, restless, and crowded.
Small groups of plants also make
the tank seem crowded
Do not use same species in more
than one location
8. MID-GROUND PLANTS ARE
CRITICAL.
Any plant that is a third to half the
height of the tank can make good
a midground plant
Slow-growing plants make good
midground candidates, but if you
are willing to trim often, you can
use taller and faster growing
stem plants
9. FOCAL POINT PLANTS ARE
CRITICAL
They give the eye a place to rest
and return
-Golden ratio and rule of thirds
If you follow the rule of thirds, you
will have the option of four focal
point placements: left front, left
back, right front, and right back

10. SHOW A LITTLE
BACK WALL.

11. AVOID TOO MANY RED
PLANTS.
One or two red plants at focal
points is enough. Put another
way, no more than a quarter of the
species should be orange/red/pink

SECTION TWO:
CONTRAST & ANTI-SYMMETRY
1. OBSERVE STRICT
TRIMMING
Don’t over-trim one side of the
tank

2. AVOID A SEA OF
LIGHT GREEN
Don’t put two green stem plants
next to each otheR,
If you have two light green plants
next to each other, one could
be a stem and the other a grass.
Otherwise, put a dark green or
red plant group in between
E. lineare is
one of the few bluish green plants
in the hobby
Use an earthy or brown Cryptocoryne in the midground somewhere

3. USE A MIX OF STEMS,
GRASSES, AND GIANT
LEAF PLANTS
Balance stem plants with
rosettes
Grasses, Echinodorus,
Cryptocoryne, Eriocaulon,
Nymphaea all act as foils to a sea
of stem plants. But don’t put two
grasses next to each other.
Don’t forget wispy. Bold and large
plants are common, but thin,
wispy plants offer great contrast
and make the tank seem lighter.
Perfect candidates are Eriocaulon
cf. fluviatile (Feather Duster)
or the underused Eleocharis
elongata and Hydrothrix gardneri.

4. DON’T PUT DARK GREEN
PLANTS IN CORNERS
Putting dark green plants in both back
corners will force attention to the
center of the tank and make the tank
look smaller.
Brighter plants in corners look
better.
• The best place to position dark
plants is in between or in front of
bright ones
5. DON’T PUT BRIGHT RED
PLANTS IN CORNERS

6. DON’T PLACE PLANT
GROUPS OF THE SAME
WIDTH OR HEIGHT NEXT TO
EACH OTHER.

7. ADD AN ELEMENT OF
CONTROLLED CHAOS.

One or two
wild-haired plants can be used to
shake up that uptight stiffness.
Candidates include:
• Aponogeton ulvaceus
• Lagarosiphon madagascariensis
• Persicaria praetermissa
• Any of the arched or sideways
growing Rotala rotundifolia
variants
• Juncus repens
• Murdannia sp. ‘red’
• Crinum calamistratum

9. DON’T MIX TWO OR MORE

SPECIES INTO ONE GROUP–EVEN IF THEY ARE SUBSPECIES.
This is a Nature Aquarium style
technique. It reduces contrast
between groups

10. AVOID SYMMETRY
AT ALL COST
Even
placing a big bush or a clearly defined
plant right in the middle is a mistake

11. ...AND ALSO AVOID
SECONDARY SYMMETRY
avoiding minor mirror effects like
equal-sized bushes on opposite
sides of the tank or equally bright
plants at exactly the same distance from the center

SECTION THREE:
FOREGROUND & SUBSTRATE

1. CREATE THE RIGHT AMOUNT
OF FOREGROUND GROWTH.
Let some foreground plants almost
touch the front glass while others
stay an inch or two back
It’s fine, even recommended, to have
some substrate visible near the front
of the tank

2. DON’T LET FOREGROUND
PLANTS CROWD AND PRESS
UP AGAINST THE FRONT
GLASS.

3. USE SOME OPEN OR
EMPTY SPACE IN THE
FOREGROUND.
Every square inch of substrate does
not have to planted. A little empty
space gives the tank a more
relaxed look

4. FOREGROUND PLANTS
SHOULD NOT BE PLANTED
PERFECTLY PARALLEL TO
THE FRONT GLASS.

5. DON’T ALLOW EQUAL
AMOUNT OF FLOORSPACE
FOR EACH FOREGROUND
PLANT

6. USE CURTAIN PLANTS ON
THE LEFT AND RIGHT FRONT
IF POSSIBLE.

7. CHOOSE THE COLOR OF
THE SUBSTRATE CAREFULLY

Traditional Dutch style tanks use
inert natural brown gravel. Black
blasting sand or dark clay soils like
ADA Aquasoil are traditionally not
used, but will not count against you
in a contest unless you have large
swaths of substrate exposed.

SECTION FOUR:
EVERYTHING ELSE
1. USE AN AQUARIUM THAT IS
AT LEAST 24” FRONT TO BACK.
Tanks with 18” or less front to back
depth need extra focus on the midground as well as a perfectly
executed plant street to add a
feeling of depth.

if you have just 18”then you need to take a lesson from
Nature Aquarium style and depth
using a lot of midground groups and
strongly tapering plant streets.

2. COVER ABOUT 80 TO
90% OF THE SUBSTRATE
WITH PLANTS

3. A NATURE STYLE ‘SCAPE
WITH PLANT STREETS DOES
NOT MAKE IT DUTCH.
No U-shaped plant layout (or upside
down U)

4. IF YOU DO USE DRIFTWOOD,
USE SMALL PIECES COVERED
WITH MOSS TO SEPARATE
SOMEWHAT SIMILAR
GROUPS OF PLANTS.


5. YOU DON’T HAVE TO USE
SUBSTRATE TO CREATE AN
UPWARD SLOPE TOWARD
THE BACK

6. WHAT ABOUT THE FISH?
A dozen or so fish of one main species
is the minimum

7. USE AN EARTHY OR
BROWN CRYPTOCORYNE
IN THE MIDGROUND
SOMEWHERE.

8. DON’T MAKE
BACKGROUND PLANT
BUSHES OF THE SAME
WIDTH AND HEIGHT.

9. DON’T OVER-TRIM ONE
SIDE OF THE TANK

10. REMOVE THE
HARDWARE BEFORE
TAKING PHOTOGRAPHS
FOR (ANY) CONTEST.

11. FERTILIZING YOUR
DUTCH TANK

EI: maybe too fast of growth! Too much work
My suggestion is to dose half or
one-third strength EI with moderate
levels of CO2 and light. If you have
hungry plants, you can always insert
fertilizer tablets deep into the
substrate under those plants


You need to be ruthless
in your plant selection. If a Rotala
or Ammannia stunt in your tank,
move onto something you can
grow without issues. Select a
dozen that you can grow really
well and get going!


Joe Harvey:

Two basic ingredients you need to
begin with are big full groups, and
dramatic contrasts in height

take a
black & white picture of your tank
and see if there is contrast without
color

Ive reorganized the order of my tanks so I can better keep track of them ie. Tank 2 moss tank is now tank 3. This helps in any confusion I had when tracking tanks they are in a sort of order now. Rather than taking time editing my old journal id rather create a new thread. Pics will be current (for the most part) as they are posted. I am not aquascaping. I am just farming.

Hi guys!

I'm new here, but not entirely new to planted tanks though I've been out of the hobby for the better part of the last decade between kids and moving a couple of times - but finally in a spot where I can do something again. I'm mostly going to be making things up as I go along, but plan on a lot of automation (I want to integrate everything into home assistant) and a lot of DIY as I love the challenge of building things out myself.

The starting point:

I picked up a 90P rimless, low-iron tank on a great deal.

Media (1).webp

I have a rough idea in my head for a stand to be built from plywood - just have a couple other house projects to finish off before starting that built.

Wife says I can only have one aquarium, so for this tank, I want to go all out with a sump to allow for auto top off, and auto water changes, auto fertilizer dosing etc. etc. I have half a plan in my mind.

I've also started on the light fixture which I've modeled up in CAD, and plan on making out of an 8020 extrusion, and some 3D printed bits.
Screenshot 2026-06-01 092809.webp
I'm using bridgelux gen 3 thrive CW (3000k) and WW (5000k) LED strips which have super high CRI at 98+ along with some specific XPE2 wavelengths that I'll solder onto some starboards. Far Red (730nm), Red (654nm), Cyan (495nm), Blue (455nm), Visible UV (415nm). Each segment of the white channels will be on its own driver so I can adjust left to right brightness in thirds, and each colour channel on its own driver so I can vary each channel on a time-based approach.

These will be run from a custom PCB board with Meanwell N-LDD drivers, and will run ESPHome on an ESP32 so it can link up with my Home Assistant installation.

That's it for now, this will probably be a very slow build so be warned if you follow along!

Hi All,

This is something I've been wanting to do for years, and I think I finally found a sensor that will work. I've always had trouble reading the API tests, and I've always been miffed that the reefers get the cool digital test readers - and wanted to take a crack at building one that could potentially read any freshwater test given a blank/known concentration as a calibration.

1781623047516.webp


A sensor came out from ams (AS7343) in 2022 that unfortunately has been made EOL, but has a replacement (TCS34488M) with a similar package that might work for future versions.
1781623191534.webp1781623224412.webp

I recently got my hands on a qwic version of the AS7343 sensor from sparkfun, and figured its time to put together something.

Goals:
  • As cheap as possible
  • Universal as possible
  • Fit API glass/plastic vials (not sure yet if the plastic vials will read ok)
  • Start with Nitrate/Phosphate and see if I can add more there

I figure I'll need 2 light sources (warm white, and IR for reading the phosphate test), but can use the same sensor array across most tests. I can use a small-form ESP32 as the MCU to give it USB-C power, wifi/bt connectivity if needed, and keep it small. Small/cheap ~1.3" OLED screen for displaying results/selecting tests.

Enclosure will be 3d printed.


1781624471200.webp1781624649923.webp1781624676599.webp
First pass at a sketch - I might drop the screen if I can give the device a web interface though, which will make the device even smaller/cheaper, reduces the need for physical buttons on the unit, and a 2nd pcb entirely. Also not sure if it will need a cover for the top of the vial, or how much ambient light will affect the reads. TBD. Will order some XIAO ESP32S3 to play with and see how far I can take it.

I'll log progress here, and am very open to suggestions and ideas. If successful, I'll release the files so it can be easily replicated.

Time to start a new thread.

I’ll fill in some details later, but I’m working on the hardscape now. Any and all criticism is appreciated. The vision is nothing more, and nothing less, than something appealing to the eye.

90cm x 30cm x 30cm Lifegard Aquatics ultra clear bookshelf tank. Buce and anubias on the hardscape, stems towards the back and center, mid to front carpet with some changes in shade and texture down to a flat grade on the right side of the tank.

Lily pipe inlet and skimmer will be in the back left corner with the outflow in the front left to hopefully achieve circular flow. I’ll be running an in-line diffuser. Light will be the P600 Pro that I regrettably did not upside to 900. Oh well. I’ll mount it high and hopefully it’ll have enough spread.

I have some dragon stone and red lava rock rubble I’ll use at the base to blend into the substrate, as well as some stratum I may or may not cap with.

Sorry, but I just find this hilarious! Perhaps they'll ask scientists if there's a way to turn down the brightness and photoperiod of the sun.

I have good nutrient, CO2 and light levels, why do my plants still grow poorly

Many hobbyists spend time perfecting tank parameters, nutrient, light and CO2 levels, thinking that this automatically translates into optimal plant growth. While these factors are important, there are many other factors that affect plant growth.

Replanting_1.png


For example above we have two groups of Lysimachia parvifolia growing side by side. Both groups have access to the same parameters, CO2, light, nutrients, substrate. However, the group on the right is growing poorly with darker, melting leaves and the group on the left is growing super vibrant red, with hardly a blemish.

This is not due to some arcane reason such as water flow hitting one group but not the other. The reason here is much simpler - the group on the right has been trimmed back repeatedly and allowed to grow in the same spot for a few months, while the group on the left was uprooted in the last month, divided and replanted. Overcrowding, both above and below the substrate, resulted in poorer quality new leaves being produced for the group of the right. This poor growth happened despite great growth parameters, a ton of CO2 and nutrients in the water column etc.

Different plants have different tolerances for overcrowding and aging. Some plant species regenerate well from repeated trimming cycles, others need replanting more frequently. Having great growth conditions delay deterioration of old growth, but most plants grow more optimally with regular replanting to clear congested rootzones and old growth.

Trimming and replanting cycles

The exact number of trimming cycles each species can regenerate from, and the time it takes for old growth and root zone congestion to take effect is different for each aquarium environment. Generally, if aquarium conditions are more spacious, and there is more substrate depth and stable growth conditions, plants can grow in one spot longer. Stressful growth conditions, poor nutrient/CO2 levels and even poor microbial balance accelerate deterioration of old growth.

Interestingly, on the opposite end, overcrowding and root zone congestion also happens more quickly in fast growth aquariums. Hobbyists that throw a ton of nutrients and CO2 at their plants run headfirst into the brick wall that is overcrowding. This can be countered somewhat by using a portion of slower growing plants in an aquarium. The slower growing plants can be worked less often, while the fast growers are on a more regular replanting cycle.

Many aquascapers avoid stem plants because they require much more frequent replanting to grow well. Species such as Anubias, Bucephalandra and Cryptocoryne species on the other hand, have extremely long replanting cycles, and can grow for years without needing to be uprooted.

2hrAquaristDSCF8006E_Full_tank_show.jpg


In this stem plant heavy aquascape that is around 7 months old, every single plant cluster has been replanted at least once. A sample of the replanting cycle for each species:
  • Rotala blood red SG - every 4 months
  • Rotala macrandra mini type 4 - every month
  • Lysimachia parvifolia - every 2-3 months
  • Xyris difformis - every 5-6 months
  • Elatine triandra - every month
  • Rotala florida - every 3-4 months
  • Staurogyne purple - every 5 months

Uprooting, cleaning, replanting:

2hrAquarist15_1024x1024.jpg


To refresh stem plant bushes, we will replant the fresh tops of the plants, while discarding the older bottom portions.

The first step is to uproot the entire stem plant bush. To control the mess when pulling up the soil, we recommend using a water siphon to vacuum the area when pulling up plants. The siphon should be held very close to the point where the plant is being pulled up to catch the soil debris.

We will try to remove as much of the old root system as possible and also remove any organic debris that has accumulated in the area. While organic debris contributes small amounts of nutrients through decomposition, a build-up of organic debris will interfere with root formation for more delicate plants and will also trigger algae. To stir up the organic debris, we use a turkey baster to spray jets of water onto the substrate while vacuuming with a siphon. The aquasoil should look clean before we start replanting.

Mini_macrandra_type_IV_green.jpg

The next step is to sort the uprooted stems and select only the healthiest heads for replanting. (A) is a middle portion and already has several branches. It is a poor choice as it will give rise to very uneven growth. (B) is a weak cutting- observe how thin the stem is, and the lack of colour. If replanted, it has a lower chance of success. (C) is ideal. A thick, singular healthy top with healthy new leaves.

2hrAquarist16_1024x1024.jpg


Enriching the substrate with new aquasoil

When plants are uprooted, we can take the chance to enrich the substrate. There are two main ways to replenish depleted aqua soils. The first is to use nitrogen-rich root tabs. The second is to add fresh ammonia-rich aquasoil periodically. A good rate is adding 1% of new ammonia-rich aquasoil per month. For example, if you have 30kg of aquasoil in an aquarium, adding around 300 grams per month will work well. You can add new aquasoil during plant replanting cycles. Simply remove a portion of old aquasoil with a water siphon or spoon, then add and mix in the new aquasoil. This method may be cheaper than using root tabs in the long run

Add new aquasoil
adding new aquasoil


Replanting entire planted aquariums regularly is not feasible for most aquarists. So having an aquascape consisting solely of fast growing stem plants can be a nightmare when overcrowding and age sets in. Aquarists should plant a mix of slower growing species and species that do not need frequent trimming/replanting. Then the fast growing bunches can be replanted on a rotation basis - only one species is replanted during each weekly water change for example.Replanting work requires skill and dexterity. It is often difficult for beginners to manage, until some experience is gained. It becomes much easier with practice and time.

In this aquarium, Rotala florida, Xyris difformis, Syngonanthus species are all plants that can grow for months without replanting.

2hrAquaristDSCF7609E_4ft_side.jpg


With consistent maintenance, aqua soils do not need to be replaced. The aqua soil in this aquarium is 1.5 years old APT Feast. Regular enrichment and clearing of detritus allows the substrate to perform like new. By renewing plant growth continually through replanting, and enrichment, planted aquariums also become more algae resistant.
