Hi everyone,
I have a 110 gallon tank with live rock, live sand, live rock in the sump and a Marineland 300 protein skimmer. I have LED lighting and the cycle is 10 hours on, and the rest off. I have 3 power heads, all located towards the top of the tank. Current water parameters: Ammonia: 0, Phosphate 0.25, Nitrate 20 (although I measured about 30 minutes after a feeding). Water temperature is 80.
I added a green star polyp to the tank on Sunday, and unfortunately it hasn't opened yet. See photos below. Is this normal behavior or should I be worried? All else in the tank including a hammer coral, many zoos, torch coral, pagoda coral are all doing well, including the fish (4 small clowns, 1 fire fish goby, 1 cleaner wrasse, 1 blue damsel, 1 blue reef chromes).
Any suggestions? He is placed mid tank with moderate flow.
