See I said fertz although im not really sure what they are I did read a little about them in the DIY co2 section but the science was too much for me is there not a good old rip off bottle of somthing I can just put a capfull of in my water changes?
My blyxa that was in Eco and in low light grow better then blxya in high light in sand . They are both in the same tank and get same co2 and ferts. One in eco was Much thicker then the Blyxa that was right under the light in sand
