I've decided to approach these qt/treatment tanks like a FO tank.
I've got an eheim pro cannister filter on the 30 gallon cube and an eheim pro2 on the 55 gallon.
I'll plan to running a hob deltec skimmer on the 55. For the oxygenation and hopefully filtering once out of hypo.
The ignitus anthias look to be losing color. But the lyretail and resplendent eat well and look healthy.
The bellus is eating very well and it's color is back. The last remaining chromis has fin rot on its tail. But otherwise is eating well.
On the DT, I purchased a used larger 1050 ATB cone skimmer with the recirc mod. It came missing the air line and with an eheim 1260 with a cracked housing. Nothing fit snugly like on my V2 econocone 840. The cup sat loose on the cone and leaked, the pump fittings were somewhat loose, the discharge pipe into the center of the skimmer was loose and slipped out. Overall I'm kicking myself for buying this used. :rolleye1:
I tried to salvage the situation by fitting the 840's sicce pump cause I thought the eheim was vibrating too much and got hotter than the same two pumps I have for returns in my sump. The flow from the sicce pump was actually about the same as the eheim.
It's working OK other than the leaky cup which probably can be solved with a new gasket. I'll see how things go.
On the up side, it fills it's section of the sump with an inch to spare (less than 1/2" if I used the 1260). And is physically the largest ATB skimmer I'd be able to use.
Eventually, I've got to break down and just net the wrasse out of the DT. It just won't get in the trap.
On the other hand, it's healthy and eating like a pig and has never shown any signs of ich.
