I cant see a noticeable advantage to using 1" if your pump output is only 3/4". but it wouldn't hurt anything

Thanks!

I am also trying to figure out what return pump to buy. I am running a bean animal with a coast/coast over flow. 1" drains.
I am looking at:

Fluval Sea SP2
Quiet One Pro 4000
EHEIM 1260 or 1262


I have all read great stuff about these pumps. The SP2 and Eheim are pretty high cost and then Pro 4000 is a lot cheaper. Any thoughts on these?

Thanks

I havent tried the fluval but my quiet one is awesome. thats my recommendation.
My eheim is good but it makes a weird noise on start up. not a huge deal but thats it really. The quiet one is low power too

I am leaning towards the Q One 4000. The head height GPH is still good. The SP2 loses a lot of GPH even at 4.5 feet.. hmmm

Check out Sicce Syncra... I'm running a 3.0, it's virtually silent, and I bought it for $80 on amazon (bout half price).

I use a transparent true union check valve, so I can easily monitor its condition/performance and maintain it as necessary. I also run an Fluval SP4 wide open, so it would take one determined critter to get down to the check valve. Basic setup before some tuning/modifications.

Forgot to mention, my check valve is also transparent so easy to see if it's getting gummed up.

how do you find tuning the drains with ball valves?

They are precise enough for me. Gate valves would be a nice to have, but not a need.
