HOO-rah!!
We have gone from 100+ down to 50 with massive water changes, MarinePure block, ample live rock, vinegar dosing for 3 months, a sump clean-out, and Chemipure, but nothing was budging it down below 50 for long.
Three days of NoPox, and we are right about 25.
The resistence of this case (complicated by the need to dose Prime after invert and some fish death during an 8 day blackout) has been epic.
I'm dosing into the sump, once daily, and the corals are delighted. The candycane has been tight to its ribs and is starting, in however small a way, to puff up. The fish are doing well.
The only downside I'm seeing is a diminishing of pods and amphipods, but not an extinction.
