I haven't posted in quite some time because my reef was doing great. That is until 2 weeks ago.
My 10"diameter mushroom leather shrunk. I thought it was just sloughing as it did occasionally so I didn't pay it much attention. A few days later my shrooms
and zoes started to get gummy. Within a week my leather completely melted, when I cut the rest of it off the rock it smelled terrible. All of my snails and hermits died, my coral banded shrimp died also. I have lost almost every softie I had. My long tentacle anemone died but my tube anemone did just fine.
My fish all survived with no issues at all.
Since then I have done massive water changes adding up to about 150% of the total galonage of the tank and sump. During this whole thing none of my parameters did anything. ph 8.2, alk
9dkh, nitrate 0, nitrite 0, ammonia 0, phos 0. My protein skimmer skimmed out tons of skimmate and now is finally back to normal.
Currently my tank looks to have stabelized and I have added some shrooms
with no ill effects. I also added a BTA for my clown to have a home. That also looks fine. I just added 100 certh and 100 nassarius snails.
After all of this: here is my question. I now have a hair algae outbreak and think it is because I lost all of my cleaner crew. I currently have no hermit crabs and want to know if I need to replace them. It seemed all they did was kill my snails before this.
Also: does anyone have any idea what happened to my tank. Do leathers just kick off like that and take the whole tank with them?
