Day 34 - Updates, Additions and Findings
Water change
- 65 - 70% twice/week. Moving forward will be once/week.
Co2
- I have tested with the Hanna Co2 kit and i get about 40 ppm when lights come on and relatively stable
- Got a HM Ph meter as well for ease of use
-- 5 am - 6.9 (Co2 turns on)
-- 7 am - 5.9
-- 1 pm - 5.7
-- 4 pm - 5.9 (Co2 turns off at 3 pm)
-- 10 pm - 6.4
- Ended up increasing the bubble count slightly (I don't know where people get 1 bubble/sec rule mine is going crazy fast). All fish doing well.
Light
- Went from 60% to 80% intensity.
Testing
- Phosphate 0.25 ppm, Nitrate 0.2 - 1 ppm
Additions
- Added some H.Pinnatifida
- Added small stalks of B.Carolina (took over my prior tank - so being very careful)
- Added some more hairgrass mini
- Added 3 Nerite snails, 3 small Amano shrimps
Plant updates
Main view - Overall happy with the growth so far, definitely some Algae.
Side view
P.Decannensis street - I like the smaller ones in the front. I might need to re-think about this since I had wanted something smaller width wise. Maybe a Tonina sp ?
R.Florida and R.Tulu - These are very slow growing but very stable. The tulu need sometime but no melting and looks good just need to grow
R.Indica Bonsai - Doing well, got some orangish hue on top.
L. Arcuata - This plant does NOT like my tank - it won't grow - I am thinking of removing this and just filling it with R.Blood red which is thriving.
@Dennis Wong @Burr740 or others any thoughts on this ?
B.Japonica - I don't have a PAR meter nor the iphone app but i think the reddish tones of the thriving Blyxa tells me there is good amount of light.
B.Carolina - new addition, looking forward to see tall plants with pink plants to merge the AR to the L.Wilsonii. THe L.Wilsonii and the L.Hippuroides needs time.
S.Repens Melt -
@Dennis Wong had warned about this on his website, but this plant develops these spots and then the leaf just melts. Tom Barr made a comment on this decades ago and said it is just the plant adapting so waiting to see what happens
Fertilizing:
I saved this part for the end since I wanted to understand it better before making changes. After watching Tom Barr’s recent video, I got more interested in the EI method and went down the rabbit hole a bit. I also came across Greg Watson’s old “Guide to Dosing” ,worth a read if you haven’t seen it.
My main takeaway is that the EI approach is the simpler approach The regular water changes make it forgiving, and you don’t have to constantly chase test numbers. In my case, though, I prefer slower, steadier growth with less trimming, so I’m aiming for something between lean dosing and full EI. I initially wanted to rely mostly on soil based nutrition, but that doesn’t seem realistic long term, so I’m taking a more calculated approach with water column dosing.
Rather than tracking every parameter, I’m just going to follow nitrates and use that as my guide for plant growth. I trust Dennis’s macro and micro ratios in APT 3, so instead of tweaking everything, I’ll only adjust based on nitrate trends.
Here’s the plan for now:
- Start with 1 mL of APT 3 daily, which should give about 0.5 ppm NO₃ for my tank.
- Dose 2 mL after every water change.
- Recheck nitrates before each water change and fine-tune from there to ensure Nitrates around 1-2 ppm
