WHICH PUMP DO YOU LIKE AND WHY

[Mr Cob]

I personally prefer smaller internal pumps. No real reason to pump more than 500GPH or so through the sump. If you're using your pump to feed auxiliary stuff like reactors, then a bigger pump may be the answer, but if not, go small internal IMO. They are quieter and less risk of leaks due to bulkheads and/or plumbing.

Totally agree.

I run a quietone inside my sump and just like the name it makes no noise.

Iwaki MD30RLT Water Pump (Japanese Motor) is what I have which is only 510gph which goes through chiller then up to display. I have had in sump pumps that would after 1y drop in flow or get weak and im hoping this pump wont do this.
