Quite replacement for Comline 900 pump???

[scolson]

I recently purchased a HOB refugium to help control the pH in my sump-less, and fish-less, 40 Breeder invert/coral QT tank. It's been working great but the feed pump is a Comline 900 AC pump and it is by far the loudest thing running in my home.

I've been trying to find a DC (or quieter AC) replacement for this submersible return pump but so far, no luck.

I'm looking for flow-rate between 150 and 225 GPH and a 1/2" output to match the existing piping on the refugium.

Any recommendations?

Something from the Jebao DC pump line up.
