Hey Groovers, I've got green algae all over the top of my media.It doesnt seem to be affecting growth but i would still like it gone. I am trying new media called Fytocell, Fytoflake its supposed to be impossible to over water. Its white chopped up foamy kinda stuff. Seems good so far except for the green on top. I have some stuff for ridding fishtanks of algae and when used correctly says will not harm marine plants but i am not to sure and dont want to take the risk. Do any of those "zyme" products eat algae. What about biobugs??
