That reading is salinityI tested my alkalinity and it’s my normal 1.025. He’s been closed for about a month or so.
wild guess, alkalinity issues
Oh sorry I read it wrong and yes just tested and it’s 8Alkalinity should be somewhere between 7-10. That's salinity
they have been growing really well until like I said my anemone moved.That reading is salinity
alk should be between 8-11dkh
Zoas must have iodide, not iodine in their water and under moderate light and water flow. They seem to do best in the lower half to third of the tank in an area of low-medium to medium-high flow. Too much flow may make it hard for the polyps to open. You will know your zoanthids are ‘happy’ if they open up and are fully extended without seeming to stretch so far upright.. The majority of zoanthids have symbiotic photosynthetic zooxanthellae (I dare you to try and say that three times quickly) and are therefore best kept with at least moderate aquarium lighting as mentioned for production of zooxanthele.
Zoanthids require the standard water parameters that are good for keeping just about any of your corals healthy. You’re aiming for water temperature about 78 F, salinity somewhere around 1.025 specific gravity) and normal hardness 8-11 dKH) and a pH around 8.1-8.3.
However, if your polyps were previously open and have recently closed up, this should be taken as a serious sign of a water parameters issue. The first things I would check are ph and salinity. In my experience, zoas will close up if there are swings in salinity.
angry or irritated by nem. They recover to normal slowly but will recover. Try GENTLE burst over them with a turkey baster which usually perks them upYeah they

Well it’s been over a month....It can take a couple of days.
