Hi! You want 20-40 times GPH running through your tank. I have a 30g and I have a 200gph return pump, a Hydor Koralia 525, and a zoo med 214 160 gph. Lots of small pumps is better than just a big one.

Hope it helps!

I would add two 550's or two 750's to a 39g tank. If aimed correctly there shouldnt be any sand storms.

I like the nano's pumps there small not so bulky so will the 425 be ok?

 

[nuwave59]

No that's not enough in my opinion. I go with Carey! 2 Pumps!

Ok how about a 750 and a 425? All together 1175gph

If you feel more comfortable with those then you should be good. The 750's really arent that big and the 425's are a bit weak, I have them in my 20g tank.

But if youre dead set against the size then go for it! Some flow is better than no flow.
