Hi, I need some advice please.
My tank has been running for 6 months, I used the water from my old tank when I moved everything over to the new one, (just over half the volume of my new tank) my old tank had been running for just over 13months without any problems, all water parameters were spot on.
I have since bought some corals for the new tank. I have an elegance coral, a monti, green geuinepora, red geuinepora, torch coral, sun coral and a hammer coral.
All my corals are doing really well and growing nicely. That is except the hammer! I am on my 3rd hammer now, I had a nice big hammer to start with that got brown jelly disease, then I bought a branching hammer, that got brown jelly disease and my latest hammer has brown jelly disease!!!!!!
All parameters are fine, temp 25.5c salinity 1.025, ammonia 0, nitrite 0, nitrate 0.05, ph 8.2, kh
9, phos 0. Calcium 420. Magnesium 1300.
Why are all my corals fine apart from the hammers? Any advice greatly received. The hammer coral is one of my favourite, just wish I could keep them alive.
