You're welcome, Cheeks. I run a turboflotor multi SL on my system, too, but it uses the OR1700, which is a modified PH2500. That's the stock pump for the Multi. Good luck on that skimmer cup. Their website address, by the way, is
Aqua Medic.
Are you running the Turboflotor on your cube? I have mine running on my 90 as well. Some people have trouble tuning the regular Turboflotor, but I've had no trouble at all with tuning the multi. What's been your experience?
