I've had my zoas in my display now for a while (some up to two weeks) and not seeing many polyps opening and some frags have none opening. I'm gradually moving them over from my QT (temporarily stopped now as they look healthier in QT). They were dipped before going into QT 5 weeks ago and have seen no pests other than some minor algae issues which the snails manage just fine. All were open in QT just fine.
They're on bottom on display and the light (Radion XR-15 G4 Pro) is at 50%. The water in QT was from display so chemistry matched. Water parameters are solid and stable. pH 7.9, nitrate 3.0 ppm, phosphate <.03 ppm, temp 79F, Alk 8.0.
I do have a diatom bloom in progress, but have been doing WC to keep under control and regularly brush off rocks. Do not see any brown on the zoas. I have palys as well but they seem to be opening ok but not great.
My birds nest, duncan, pavona, cyphastrea are all doing very well with good color, growth, and new heads on duncan and they have been in tank for 6 weeks.
Any thoughts? Need any additional information?
