I have a 50 gallon FOWLR
tank. I have gone through the initial diatom phase, followed by green algae, and then red cyano
. They all cleared up and my tank was looking great! Now I have started getting brown diatoms and some cyano
on my sand again.
. The only thing I have donw recently is added about a pound or 2 of new live sand and a couple pieces of live rock. I did add a new fish but would that throw my parameters off? Would the new sand and rock be causing this?
