The new SeaChem Aquavitro Division Skimmers are amazing, they have 3 models, 125, 250, & 500 the numbers correspond to gallons they're built to handle. They're powerful, well built, relatively inexpensive, plus they have a small footprint!
This is the one! I recently upgraded to this skimmer and it’s the best I’ve ever had out of 5-6 skimmers. Great price too. I paid close to $600 for a new one recently.
I run a Jaebao 13000 at 85%. You can push massive amounts of water through these, and the more water you push, the more air you suck. You can crank your pump and just use the gate valve to adjust the water level and the wetness of your skimmate.
