I have a Rossmont SX250 on my current tank. Great skimmer. AC pump reliability with complete control (if you buy a Waver). You can even schedule it to turn down/off to align with dosing certain things or feeding so it doesn’t go nuts. It isn’t as quiet as some DC options, but it has been an absolute beast. I run it on the Waver with my Rossmont RX1400 return pump which is also controllable AC.
I have run many over some 20 years of reefing. Hanner (air stone driven), SeaClone, Euroreef, Deltec, Volcano by Spazz, Bubble King, ReefOctopus, CPR hang on and Currently ATB which is my favorite and current skimmer which I have been running for a number of years now. Extremely quiet, very efficient and have never had and issue with any part. They were more popular years back but rarely heard of anymore.
