bleached coral

Hello folks, I have been reefing for only 6 months and I am making some mistakes! I have a bunch of corals right now and everything else seems to be doing fine. I have some shrooms, blastos, some zoas, a favia... I have a bunch of LPS frags lol. I tried my hand at some SPS. I have a Millie and...

Hi All, I have a 90 gallon tank and have noticed some coral that aren’t doing so well. The first guy is a bowerbanki, which I have had for a while. It looked great at first, until I switched my lights and it looks very shrunken with skeleton exposed. Originally, I had 2 AI Prime HDs but switched...

Hello All, I'm looking for help with health on my 240 gallon system. It's been running for 2 and a half years, and I can't seem to have success with my SPS coral (and now appears one of my torches is dying.) I'm attaching some pictures of some SPS coral that appear to be dying. I think my...

I just got my first set of corals and a new light system. The AI. (See photos) i don’t know if my corals are bleaching out and if my setting is too high. This morning the park was 140 over the big red (monti?) coral that I had for a while. The new alien eye has a white strip (I moved him...

Hello reefers, I have 2 hammers both with about 5-6 heads that over the past 3 weeks have started to turn white. My first thought was bleaching from light, but the odd thing, they are bleaching on the underside not facing the light. My tank is mostly euphilia and my lights haven’t changed in...

Hi all, I've had a dragon soul torch in my tank for about 2 months, no issues, it and all the other coral have been doing well. I purchased an Indo Gold torch as a Christmas present for myself about a month ago, and the seller recommended light intensity on the higher side to keep the color...

We got some new corals in 3 days ago and we’re now having some issues. Yesterday morning one of the new corals was half covered in a white stringy web-looking thing that was kind of flapping in the flow. I blew it off, only to find the coral below was bleached in that spot. Very back middle...

I'm looking for advice on how to tune my lighting setup, which I'll be finished putting together next week, and because I have bleached corals at the same time I'm looking for some help on how to configure things, so that I don't make things worse. A lot's gone on and I've had a hard time...
