Jebao RW-4

Will this pump be enough or too much for a 20g high? I want to replace an old powerhead I have in there. Maxijet 900 I think? I also have a Fluval Sea circulation pump running as well. Forget which model, either CP-1 (265gph) or CP-2 (425gph).

Thoughts?

Works fine in our 20H

it will be perfect

Awesome. Should I run just the jebao? Or keep the fluval sea pump as well? I found one with the controller for $50 on Amazon so I couldn't pass it up. Haha

will one of these work for a 30 breeder or should i do a rw-8?

also is the rw quieter than the wp?

Yes rw 4 would be fine on a 30 I think they're a bit quieter
