Male clownfish has healed perfectly and is aok.
Biopellet reactor was clogging last week and so the tank appeared to have some sort of cloudy episode. Nitrates were at 40ppm so did a emergency 40% water change. Did another change 2 days later and cloudiness has subsided. Changed the biopellets into a reactor that keeps them tumbling. After water change calcium was on 300ppm. Added a heap of caulerpa back in as I had taken it out to seed the propagation tanks. This may have contributed to the nitrate increase as well.
Yesterday: noticed very lower part of clam was retracted in. Not a good sign. Completely lost my yellow millepora that I have had for a year with no issue. tissue sheared right off the skeleton. No other signs of stress on the other SPS but some of the acro has browned out (including a dallas frag!)
Today: checked calcium again and down to 275. Added 1/3 of randy's needed to adjust; will add rest tomorrow after re-testing. Nitrates down to 5-10ppm (api). Woke up this morning to see clam has fully retracted and is not looking good. No signs of pests (snails etc) but there were some bristle worms underneath it possibly eating dead tissue. Doesn't smell when pulled out of the tank so I've put it on the sand for now. I don't like my chances of it coming good. Will be completing another 40% change today to hopefully help rebalance lost elements.

I'm not feeling like a good hobbyist right now. Happy to take suggestions on what I could do. I'll be testing phosphate again today to make sure I haven't gone down too low with the GFO.
