Single or double return pump?

[ahiggins]

Hello all,
Trying to figure out what I want to do in my fusion 25 lagoon. The stock pump is garbage and it "Y"s for the two return nozzles.
Should I get a replacement that's large enough to "Y" and provide flow OR get two smaller return pumps and plumb each to its own return?

I prefer 2 pumps just in case one dies then you at least have some flow.

I didn’t think about the redundancy aspect, that’s a great point

Yes
2 tanks. 1 has 2 and the other 1. Either way works.
If you have 2 and 1 fails it just becomes another drain unless you take steps like vacuum breaks.

This depends. Is this the newer MightyJet pump? I've seen a few Fusion 25s where the owners upgraded to a pair of Sicce (etc.) pumps so that they could then fit a Tunze skimmer between the pumps in the pump chamber.

Yep, that’s the tank. Mighty jet failed after 9 hours set at 1.4. Junk.
that’s an interesting idea too. I usually don’t stock heavy enough to need a skimmer but nice to have options!

That sucks. I had 2 for running for 8 months without issues on those pumps, but the IM skimmer pumps were another story altogether. Quality Control @ IM seems to have gone steadily downhill...
