Hello, ive had this tank for about 2 months now and the fish seem to be doing great, as well as the 6 dwarf blue leg hermit crabs (they have only been here for 3 days), however I ordered zoas about a month ago and I am pretty sure they are dead. My parameters are all fine so I ordered a copper and gh test because that is the only thing I can think of. Alkalinity is around 120 mg/l ph 8.2 and all other values 0. I ordered a proper alkalinity test as this is of a test strip. I added a photo of the corals below I do not know if they are dead so J have not removed them. The gh and alkalinity test should be here tomorrow, copper should be in on friday. I tried giving them reef ab plus but it did not work lol.
