A few of my LPS corals have been a little deflated this week. I tested all of my parameters yestersay and everything was great. This morning I was checking corals for pests before the lights came on and all of the corals that are stessed have a bunch of these sponges growing under them. No other corals in my tank have these sponges just this Acan, a frogspawn frag and an elegance and all three have seemed stressed this week. How to I go about removing the sponge without spreading it? Ive never had issues with sponges in the past they were always a good thing.
