Hi all!
I have an issue with my reef tank. It's a 20-gal mixed reef with anemones.
So in mid-July, all of a sudden, my anemones started splitting and moving around the tank. It's not the first time my anemones split but it was the first time they moved so much. In a few days, 3 of them died. I removed the dead anemones and did a few big water changes in the course of a few weeks. Two anemones survived and are in a quarantine box. They seem better there.
At the same time, my toadstool leather stopped opening and the other corals also started opening less. Only the Holywood stunned chalice coral seems to be going fine.
I started seeing more and more hair algae and also some brick-red slime over the rocks (please see attached photos). I keep doing a 20% weekly water change but things seem to spiral downwards. I tested the water with test kits that I have.
Ammonia: 0
Salinity: 1.025
Phosphate: 0.012 ppm (Hanna test kit, reagents expired 4 months ago)
Nitrates: 0 (NYOS test kit)
pH: 8 (API test kit)
Do you guys have any idea what this slimy thing could be? Any ideas on how to get rid of it and this hair algae and get my corals to open up again?
