My Zoa's will not open.

I have 4 1200 maxijets...on a Wavemaster pro and 12 mag return pump from the sump and a Tunze 6025 that is always on. The zoas came with this slime on them and I think no matter how good the flow, until you actually attack the slime itself, just using flow will not clear it up on it's own. I had them in an area of high flow, it wasn't helping...the slime is pretty stubborn. You can't even blow it off with a powerhead or turkey baster. I used a baby toothbrush to finally clear it off.

Yeah, I agree. Once it attacks the colony you have to manually romove it. I was just saying, once back in the tank, the deterrent from return was flow.

I was curious when it happened to mine what was happening to make the polyps not open? I never understood if they were just upset and closed, or if the slime was chemically threatening them in some way and they closed for protection. Have you figured this out?
