I've got several rocks with mushrooms in my tank but I'm having problems!
One rock I have had about 10 mushrooms on that used to cover the whole rock. They have gradually got smaller and smaller and a couple have died off all together, literally shrank to nothing then when they were minute went white and died. The rest are now pretty small, yet still look very healthy.
I also had some lovely bright green ones. There were 2 rocks with about 7 bigish mushies on. 3 of these kind of went furry in the middle leaving just a green ring.
I did think there must be something wrong with the water, but tested everything and readings are all normal. All my other corals are thriving, including a huge rock, covered in mushrooms. The fish are also not showing any signs of water problems.
My tank phosphate level was slightly raised, but for a long time it was very very high (used to use tap water with dechlorinator) and then the corals were unaffected, so can't see how the phosphates have caused this. We eventually got the phosphates down with phosphate remover and switching to RO water.
The only change to this tank is that we now have more flow as we added 2 koralia powerheads, but the mushrooms affected are quite low in the tank and though they get more flow than they used to they are not in the immediate vacinity of the powerheads, and the flow they do get doesn't make the mushrooms move.
I did wonder if I had corals that were incompatible with each other, but All I have is zoas, leathers, star polyps and mushrooms, nothing unusual. They are quite spread about in the tank too. There is more light in this tank than the old one, but the affected corals are quite low down and I only have T5 and T8.
Any ideas?
Any ideas? Is there anything that mushrooms are particularly sensitive too?
