Reef octopus ro-ps 2000int

[Metrontech]

Hey all, wasn't sure where to post this but I have a reef octopus ro-ps 2000INT skimmer which keeps over flowing

I get it set perfect and the boom u

I wake up and out of the blue it's overflowed 5 gallon of water into my bucket

I'm using it on a 55 gallon display with 55 gallon sump

One thing I have read is about the outflow pipe needing to be above the water line. Is this the issue?

Any help is valued! Thanks

Mike
