Sigh. I dealt with dino for over a year, now this. I tried to mitigate them by adding tons of bumblebee snails (~100+ of them) and they have still been able to grow all over the live rock, over flow, into certain pipes, and now in the sump all over certain equipment. ***. Is there ANY way to get rid of them??? I feel like I've tried everything. The only other thing I heard was to buy new live rocks and reset the tank. But wouldn't that mean starting over essentially?
