Hi so this is my first post on the forum. I have a 15g reef tank that I setup about 7 months ago. I have 2 clown fish a goby, a bunch of zoas, a green mushroom, gsp, and a new hammer coral I got yesterday. I’ve had hammers before (1) but it was bigger and seemed stronger. It died from a calcium deficiency. Anyway, I feel like this one is looking rough. Calcium 415 ppm. Ammonia nitrate nitrite 0. Salinity 1 .027. I drip acclimated for 1.5 hrs. Is it just acclimating? I have a 130 gph power head also and this is the link (https://www.u-buy.com.tw/en/product...light-with-dual-channel-wired-controller-nano) to the light I have. (6.5 hrs a day) the hammer it had some algae on it so I used a turkey baster to get it off but that’s it
