Yeah its not exactly the easiest thing in the world to find and I don't know why. I have been using an older model for the better part of a year and it works like a charm with no aqua lifter pump.

KollerCraft TOM RP90 Rapids Pro Filter with UV Sterilizer for Aquariums <--- This is what you need to search for I previously would have been able to order it on amazon about 6 months ago but not available at the moment.

Was this the unit?

Yup that's the one. I have an older RP15 which still works fantastic.

Unfortunately there’s basically no way of making these things as safe as a proper overflow. For one thing most of them only has one down pipe which is a disaster waiting to happen.
Even if you don’t lose siphons or the down pipe keeps from clogging it’s still going to be significantly louder than a herbi/bean animal overflow.
Sorry to be negative but I would strongly advise you to do this properly and drill the tank...you will be much happier in the long run.

Yeah, well how are you supposed to add a sump and drill a tank if it’s completely full
