I’m running two LifeReef SVS2-24 in two different aquariums. Both have Simplicity 1000 pimps now, just added second one yesterday. On tuning them are you mostly doing it off the speed control, with the gate valve almost closed, or ramping up the pump, and tuning with the gate valve alone? BTW, I’m producing a nice dark skim, just want to get an idea, what works best.
