water flow -what's standard right now?

[euromomtx]

It's been awhile since I researched flow and pumps. I've had my little tank for almost 10 years and I see that pumps are now available with much higher outputs/flow rates.
For a 130g what's currently the 'recommended' range of gph supplied by powerheads?
I already have a 1500 gph powerhead and am wondering how strong my second powerhead in that system should be?

I also have a sump with a 750gph return pump but I don't think that counts towards flow rate, does it?

For powerheads people go with 40-150x turnover depending on their setup and the animals they wish to keep.

Wow - 150x?
So in a 130g that would be 19,500gph?
Am I doing the math wrong here?
Seems like that would blast the last bit of corraline algae off the rocks!

it can be done, but usually only in Bare bottom SPS only tanks, and usually the powerheads are on a controller that ramps them up and down so its not the full 150x 100% of the time.


150x is a case of extreme flow, but SPS tanks regularly have 100x or more.

if i was setting up a 130G i would use 2 or 3 tunze 6105 or Vortech mp-40W for around 7-10,000 GPH but i would not run them at 100% all the time.
