Things are now moving along in a great direction. I ended up having a velvet outbreak (without quarantine it's inevitable) and lost most of my fish.
I picked up a 75g qt, and ran my my first group through CP and a round of prazi pro.
In my DT now I have a small adult coloured emp, foxface, lavender tang, diamond goby, a coup,e of wrasse and a chalk bass.
In qt currently, I have (all small) asfur angel, blue face angel, a stunning pair of bellus, 4 bangai Cardinal, blond naso and a small Achilles.
Everyone is eating (Achilles naturally has ich) and doing well.
I'm treating with ich shield powder for 21 days, and then prazi, with another week of observation.
As far as my sps goes - everything is encrusting like crazy, and growing well.
I've added a MASTERFLEX pump to my calcium reactor, which has turned the ph reading on my apex into a flat line. Dead even, and my tank is very very consistent.
