Re: Blue green algae question

IME, cyanobacter loooves phosphate. I've had a couple of outbreaks in one
of my tanks with a fairly heavy fish load; I don't remember what the
phosphate level was when tested but I remember it was on the high side. A
33% water change and not feeding for a few days cleared it up.
Most LFS folks will tell you that phosphate doesn't matter in a FW tank.
Don't you believe it! :)
