thx guys, for example I have the myriophyllum red which had a bad color (dark copper), no roots after a week inside the tank, it already was in immersed form. I increased the light because i already have 1 ph drop of co2 and EI fert, within days new shoots are coming in good shape, so maybe some plant can't grow without high light ?
there is a plant i really can't grow hygrophila pinnatifada, in my previous tank i used the same soil with diy co2, it was not constant, i never had BBA and that plant was growing like weed, fertilizer was almost never used, now it won't grow with high tech co2, etc, how is that possible ?
the co2 distribution are really good, inline atomizer mist absolutely everywhere in the tank, i don't know how can i improve that anymore
