Quick "Me Too" post. I'm new to reefkeeping, have a 6-month old tank with some corals and, 2 ocellatus and a PJ cardinalfish. No detectable ammonia, nitrate or nitrite, pH 8.2, SG 1.025, Ca, Mg and alkalinity all OK last time I checked. Xenia is growing like a weed, paly is growing like a weed, GSP is beginning to take over the whole bottom of the tank, torch coral and some ricordeas are looking good. Watermelon zoa looked good at first and has got progressively worse. . I did find and got rid of a nudibranch and eggs, tried freshwater dips, then what looks like zoa pox set in. Did Furan 2 (1 packet/2 cups tank water x 30 min, then fresh saltwater wash) for 3 days running. No good, zoas still melting. 2 or 3 polyps out of ~50 still open and I'm thinking of fragging those off and relocating them. All in all, very frustrating. Any thoughts from anyone more experienced, greatly appreciated.
