I have 125 gallon salt reef tank. Current 48" LED lighting. All of my basic test are coming up normal and in range. ph, nitrate, nitrite, ammonia. Yet in the past 2 months my corals are shrinking. my anemia has bleached out and shrunk as well and now not eating. all my other carpets are eating well. my big pink leather has shrunk and I haven't seen its fingers is over a month. I have had an outbreak of "baby Starfish". At least 40 of them. they look like chocolate chips stars but Ive heard it could be something else. I have lost my 3 bandit cleaner shrimp too. as for fish I have 6 green cromis, coral beauty, couple of gobies, 2 clowns, a few wrasse. Tons of clean up crew snails and crabs. What else should I test next? I didn't want to buy a bunch of tester trying to guess what's wrong. I do feed frozen fish with coral oyster feast supplements and garlic. My tank is full of live rock too. tank was purchased from someone moving and I took it over 8 months ago. I've had tanks in the past and never had this trouble.
