I think these things were rated like 300 gallons, but as with anything it is extremley over rated, I have upgraded thepum from a Mag7 to mag 9.5 and put a air flow valve on to control foam. I personally think it would be ok, but by no means would it be overskimming.
It realley pulls, I'm not sure if anyone else on the board has any experience with these on a 150?
