Hammer coral okay. Dying?

[Joethefish]

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

Yeah I will also rinse the old media in tank water. Because I am not bleaching them, should I still add some bottled bacteria?

You can. I would focus on getting everything cleaned and if you would like to add microbacter or some bottled brand sure. You will have no nitrate or phosphate the first week. Target feed

Ok. Are you familiar with Oyster Feast Coral Food. If so do you know if I can feed it to my zoas?

Every zoa is different. All will probably benefit from feedings but they all respond differently. Some close up to capture large particles, others use an invisible mucus layer to slowly drag captured food in, some don't seem to respond at all but like elevated nutrients in the water.
