I’m continuing to lose my hammers and torches. Tank is 14 months old RS350. At first the torches and hammers were puffy and great polyp extension. Growing like crazy. A couple of them still seem fine. But I’ve now starting losing them faster than they grow. I’ve lost 3 torches, 2 hammers and losing an octospawn. It seems to start from the outside, start to see small
Pieces of skeleton then slowly progresses over a 2-3 week period until dead. I tried dipping impacted corals and healthy in coral Rx it seemed to slow the decline slightly.
SPS looks better than ever, zoa growing and acans are all fine.
Parameters:
Ph - 8.2-8.4
Kh 8.3-8.8
Mag -1440-1500
Ca- 440
Nitrate - 35 was closer to 20 when issues started. Has spiked lately and working to bring down slowly
Phosphate - 0.38, was 0.2 when issues started
I’m doing weekly water changes of 10%, going to be doing 20% for the next while to bring phos/nit back down.
Any ideas what could be causing this?
