I used the chalk (calcium carbonate) treatment to help with vermetid snails. I don’t know if using this caused a bout of RTN or not, but i have lost most of the sps in my frag tank and a few colonies of Pocillipora in my display tank. I am trying the Triton RTN-X treatments now.
I cleaned my protein skimmer today and there were vermetid snails encrusted all over it. They are everywhere in my sump. I am very discouraged and I am thinking about starting over or shutting down.
I put 50 bumblebee snails in my display, frag, sump and overflow. I have seen them eating the vermetid snails but there are so many that I can’t see how they will kill them all.
Also my melanurus wrasse disappeared and I need to get another one. The wrasse seemed to eat the snails when they are floating around looking for a spot to attach too. I did not have as manny when the wrasse was on the prowl.
