Hello Community!
I've been having some trouble growing ludiwigia sp red on my highly dense planted tank. The new leaves seem small and twisted, sometimes diagnosed as calcium deficiency or as CO2 deficiency as Tom Barr responds in almost every thread I've read.
My tank:
40 Gallon planted and lots of fish
seachem onyx sand substrate
2 finnex planted+ 24/7 cc running 9 hours a day (3 ramp up, 3 on max, 3 ramp down) fairly high light even ramping up or down.
90g canister + 2 50g hanging filters (lots of flow)
pressurized and costant CO2 (yellow drop checkers)
Ei weekly NPK 15-1.5-15
Flourish comprehensive 2 times a week as indicated
Seachem Trace 2 times a week as indicated
Excel 4ml daily
50% water change weekly
current readings:
Ph: 6.4 (during photo period)
Kh: 3
Gh: 5-6
CO2 based on chart kh/ph: 35ppm
N: 20
P: 1.5
Temp: 26 Celsius constant
No algae at all, from time to time a little GSA on glass.
Any idea of what could be happening?
