Hello, this is my first post on this particular forum. I have a 55 gallon heavily planted aquarium and my ammannia gracilis will not grow correctly. It is twisted and looks unhealthy. I just did a water change and lowered the kh to 2 from 4 because I was told on another forum micronutrients may not be able to be absorbed at that pH. I have a GH of 4 and add 30 ppm of CA and 10 ppm of mg after to 25 gallons for my 50% water change. I dose EI except I only add kno3 2/3 times a week. I also dose flourish iron 3x a week. I have 6 clip on desk lamps and a beamswork da fspec. The 6 desk lamps have 10k lumes altogether, I don't know the par value. I have rotala macrandra growing and a carpet of Monte Carlo as well. **** I am using ro-di water. I think the issue could be from not enough co2 however I think I am I'm putting in enough as I can't even count the bubbles in the bubble counter. Also, I think it could be because I'm lacking sone nutirent because I use RO water. Please help me .
