what size power heads

[razataz]

I finally got a bigger tank 75 gal no more 20l What size koralia power heads do you suggest for it. It will be mostly lps with maybe 5 sps. it has a mag 5 for the return may bee 280gph when it enters the tank.

I'd go 2x#3's. Maybe a #1 behind your rock work to keep away the dead spots.

Tunze Nano streams modded to be 1100 GPH would work as well. I have 2 on my 90G and they get the job done very well.

The number I shoot for is 30-35x turn over per hour. So a 75g would need 2200-2600gph. The mag 5 seems small for the return. I would think you would want 5-700gph.

what size tunze do you have how are they modded? I read that the small nano streams are not controllable Does that mean when I get a rkl down the road I can not use the wave control part I know the k3 would not operate with the rkl.

In my 75g, I have two Koralia #4s, a Mag18 return pump (goes through chiller first), and a Tunze Wavebox.

Fullsize wavebox?

Yep. It's only cranked up about 33%.

I bought it for my 240g and tested it out in my 75g. It's so cool, I left it in.
