dying coral

Hello all. I started my tank a few months ago. It is currently testing at Ammonia-0 Nitrite- 0 Nitrate-20 ppm Dkh- 10 pH- 8 Salinity 1.25 Temp- 78 I regularly test all of this and it has stayed pretty constant. My corals were doing great, and my torch and indo hammer both split heads showing...

Hello, I have a 100 gallon Innovative Marine EXT100, and I'm losing corals. For lighting, I'm using two AI 32HDs. I run a protein skimmer, refugium (which is not at all growing my chaeto), a Carbon/GFO reactor plumbed into the manifold, and a UV sterilizer. I started this tank in November 2020...

I have had a duncan coral in my tank since September now, and the past month or so especially it has been completely closed up. Can anyone help me figure out how to encourage it to open back up. It's one of the centerpieces in my tank so it would be awesome to have it back open again. Almost...

Hello, I purchased a Purple Blasto from the LFS which opened after a few days. All was well and good in the universe. Then I decided to target feed the corals Reef Roids one day, and my Fire Shrimp attacked the coral and ripped the food out of his mouth. I thought ok, he’ll heal in a few days...

Hey everyone, My torch is not looking good. Ammonia 0, calc 500, mag 1450, salinity 35. I'm not sure what I can do at this point to prevent whatever is happening here.

Is my hammer pooping or what? Its been fine since i got it 2 weeks ago and was fine this morning then i came home to this. Looks like white slime coming out of the centre. The mouth is also open big. Hard to see in the pic but theres a 1 inch string of slime. It also shrivelled up so much. Its...

I went to a not so local lfs today, saw some really bright green almost golden hammer in a frag tank. I only had 5 mins to spend in the shop as i had to go somewhere. So i kinda impulse bought the hammer frag. The price list stated ‘per head’ so it sounds like a branching hammer coral to me. So...

So I went on vacation for 4 days and I left the AC on at my apartment. I went to my car ready to go, and my fiance went back inside to grab something. Not thinking, she turned it off and we had a heat wave. When I got home, I checked on the aquarium and it was sitting at 90 degrees... the fish...

Hello all! Hopefully this is I'm the right place... If it is not, please forgive me. I've been seeing a decline in only my euphyllia recently, and I'm at my wit's end as to what could be happening. I've tried everything, and checked all parameters (listed below). Everything else seems to be...

Hi, I have an issue I am stuck on, about 2 weeks ago my 450 litre reef tank of about 3 years started to look like corals not at there best, 1 of my hammers was not opening fully like it had, then I noticed my plate was starting to look like it was peeling and an unknown was not looking healthy...

I started my tank in March of 2019. Things have been going well until recently. I've noticed some, not all, of my SPS and LPS corals' tissue start to recede. I thought this could be due to dosing vibrant so I stopped dosing it 4 weeks ago. My issues continued so I bought an ICP test to try to...
