so matt you think the ampmaster is within a viable range? The marine depot description says it can be 'dialed back' and I do like that the new motors on them are apparently incredibly efficient.

I have been doing a lot of reading on sumps and fuges today (their design) and I am wondering if a baffle infront of the pump intake would settle any turbulence issues, regardless... buying a pump with power that would never be used would be kinda dumb. and I don't forsee a major size increase in the near future as the pocket book will strain on this one!
