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.




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.


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.



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.

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.



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.

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!

THE official "what did you do to your tank(s) today" thread!​

Let's keep it real by sharing our daily routine. Post daily if you want. It's nice to check in with fellow aquatic gardeners.

Has anyone investigated how drop checker design affects its accuracy? I have two DC side by side, both at a pH of 5.5 after CO2 injection. One is visibly yellow and the other is more yellowish-green.

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.

Welcome to ScapeCrunch, @fischman!
We would love to get to know you. Please tell us about yourself. What tank do you have?

(I hope this is acceptable as the start of a journal, new here).

Greetings, I’m Alec and this will be my third aquascape. I plan on rescaping my 60p (current scape pic below). The first time I did it, I sort of winged it in the moment. The second time, I came in with a design but it wasn’t strong enough and slowly was buried by aquasoil and plants.

So this time I’m coming in with those learnings and trying to design with intention.

Second pic below is my potential new hardscaping.

I have never done an island composition, and usually I am not a fan of them visually. But while messing around with my rocks I found this tower layout impressive.

My idea is to have the right side be a lower sandy area with some smaller rocks (not shown in pic) along with my big ass Anubias and the various crypts as well. Floaters would be above this area.

Front middle and left would be the Monte Carlo carpet, along with some Ludwigia or other stems tucked along the rocks to become bushes.

Tucked into the cracks of the rocks would be Monte Carlo & Java moss to accent it, along with my Hygrophilia.

Back-left would be stem-city. Big Rotala area with some Bacopa and Ludwigia in front of it, especially towards the center.

The middle area surrounding the top tower rock itself would be Cardamine Lyrata, as it grows naturally well in vertical bushes.

Focal point to the right of the top of the tower stone would be Ludwigia Diamond, which gets decently red.





Looking for potential feedback from those with more experience! Some of my concerns:

1. My Anubias are massive, at least for the small. I’m mostly saving them for my fiancés betta tank we hope to setup later this year. I’m a bit worried they won’t fit well into the right side area.
2. The tower is very central, which is the point of island compositions, but I worry my plants might detract from the island look, especially with my plans for the left side.
3. A commenter on my Reddit thread suggested I remove the left side “slope cliff”, instead do another smaller tower there with a sand path. Thoughts?

Thank you for reading. I will probably update this journal with other composition ideas & tweaks as I go, and of course progress pics once I actually rescape it.

Welcome to ScapeCrunch, @INFI!

As the title suggests, I would appreciate recommendations from you experts for a good all-in-one fertilizer. My plan is to dose daily using a dosing pump (with additions after water changes.)

Preferences:
Can buy in larger quantities, 500 or more.
Can be purchased somewhere local or with free shipping
Reasonable price is always appreciated.

Links are appreciated. Thanks in advance.

Both tanks contain a lot of bucephalandra stems I have recently melted by feeding my caridina tanks with mulberry leaves. I have no idea what the heck happened but all buces melted in those tanks heavily over 3 days with every other plant + shrimp being fine. Don't wanna risk the plants dying so I'm throwing them back into high tech for a few months to recover.

Set Up:
Both tanks uses heavy co2 misting
Horticulture LED lights (dimmed, so probably 25-30 watts?)
Will steadily increase light weekly if I see no issues, max is 40 watts.
Dual sponge filters. (Air bubbles help prevent co2 gassing, also seems to really help stabilize tank, so less algae)
1 Internal filter with an atomizer for misting.

Regime:
All tanks get a 30-50% water change, twice per week.
Micros dosed daily (unless I forget, which happens fairly often.)
Macros Front Loaded and only in new incoming water.

6 Gallon bucket water change:
~350tds (Using seachem equilibrium remineralizer)
~22ppm KNO3, using KNO3 + KH2PO4
~40-50 ppm Potassium due to remineralizer
~4-5GH

Buce Lottery Colors
Lots of buces, various names, collected over the years. A lot of them were ultra rare and I cannot buy them anymore. Most of the ultra rare I probably accidentally killed from trying to grow them in a "no filter, no co2" style tank. Either way, not much color in low tech, will see what lottery colors we pull once they get going with better colors in higher lights + co2.

Both tanks are planted tightly front to back with bucephalandra. Kinda hard to see it all with moss blocking the way, but my view will be your view.

Random Mosses
Some mosses I've collected as well, honestly I grow a lot of them free floating so they kinda look the same. We will find out how they look after I attach them to something.

15 Gallon, very aged sand + pebble tank.

20 Gallon long, aged aquasoil I pulled from an existing caridina tank.


Wanted to take some macro shots, but does anyone know how to take an angle show on the glass without distortion? I have a DSLR long tube lens that works under water but color rendition is really bad.

Why so much moss?
Mostly to help stabilize the tank and to reduce light bleed. Less surface for algae to grow.
