Had these in the tank about a couple of months always in the same location, they have always been open but I'm not sure they are as open as they should be, plus they don't seem to be growing much, if at all. Tank is relatively new about 3 months old started with dead rock. Zoa's are on the sand in the bottom left of the tank, Tank is red sea nano max using just the return pump for water movement with no powerhead.
Latest tests were-
alk 10.9
calcium 420
phos 0.12
nitrates 25
Alk is high as the salt has high levels (instant ocean). I am dosing all4reef.
