help #hammer coral

Hey all, I'm still having issues with the "new" tank. Ever since the old established one popped a leak, ive been having issue after issue. My problem now: algae bloom & dying corals. My star polyps are THRIVING. Everything else? Not so much. I lost a galaxea & a hammer today, al9ng with my...

A couple days ago I bought some new frags for my nano, and I woke up this morning I woke up to my frogspawn in the sand. I’m realizing the spots where I put that and the hammer don’t hold the plugs very well, but they’re my only options for a low spot in the tank. Is it okay long term to put a...

Heey I've just spotted this on my Hanmer. Any ideas?! Looks like a growth maybe its growing or dying.

I have a hammer (I think it's a wall hammer? But maybe branching hammer) is shrinking in the middle of the skeleton, and I can't tell if it is receding or splitting. Any insight will be much appreciated!

I recently picked up this hammer and have found that it is receding. Do you think there's any hope for its survival? Do you think an iodine dip would help?

Got a 2 hammers 4 months ago or so and they slowly has been looking worse and worse. I have 2 others that I got around the same time that look great. Anybody have any idea what the issue could be with these 2 guys? Thanks! Alk 8.3 Phos .16 Nitrate 6.2 Mag & cal are great

Tried to trim a dead head off this hammer and accidentally went too far!! Is it going to be okay? Should I fill that area with reef super glue? Idk what to do. Any help is appreciated please!!!!!

Wondering if someone can help. Just saw these white strings under my frogspawn flesh can anyone tell me what’s going on with it? My tank is still new basically a month old. It’s my first tester coral been in the tank for about 3 weeks was doing fine and then I notice the strings. Going through a...

Hi, I’ve noticed that most of my euphyllia have receded flesh from the bottom (hammers, torches), but they opened fine during the day (maybe slightly retracted but unnoticeable). The only issue I’m seeing is 0 phosphate. I’ve tested twice, Last Friday and today with Hanna phosphate URL. Here’s...

Photos of said Euphyillia attached. There is very little to any polyp extension. I've gone through probably 3 of these and they always do ok for a couple of months before slowly starting to wither away. System is a 65G JBJ AIO that's about 2.5 years old. I do 5G water changes weekly. I run an...

HI, im fairly new to the hobby. I have a reef tank just over 8 months old. Ive never tested my reef tank and have always hoped for the best until now. I have alot of corals that have died (Zoa/ Goni / Hammer/ Frogspawn / Favia / Acro / candy cane and even GSP) everything looked well when i...

All my other coral and fish are doing fine but my hammer coral just slowly started Shrinking for some reason. All my params have been the exact same and he’s been in the same spot for about a month. It was plump and growing quickly and now this..
