Pump dilemma ? I would appreciate any ones in sites

How long have you been running it for dose the quality seem good is there much heat buildup in the controller.

You don’t want too much turnover in your sump. The larger pump is great if you have extensive horizontal and vertical runs.

I have a150g sump now & will turn my 180g into my sump. Over 2/3 will be refugium running Triton system. Shooting for 5 times the display turnover. Think it best not to max out a motors rated capability. I like the flexibility of being able to ramp up the flow rate to be able deep clean my tank & remove suspended particles.

I am away from my tank usually between 10 days possibly a few months this winter & by running two pumps at 50%then if one goes then I can bump up the other to 100%.
Until I can get home or have someone that I deem capable of swapping out my pump. I find larger motors to make less noise at 50% then being maxed out. Will be close to 11 feet of head presser.

I also think having an oversized pump running at slower speeds will reduce heat of its components making it last longer. Just my thoughts I could be totally wrong though.

That seems to be best practice, running a pump at less than full output.

It's been running for less than 2 months at full throttle.

Backside of controller does get hot.
It does have fins on backside to aid with heat dissipation.
