Flow in a 90 gallon?

[bdiamond]

What would be a good option to increase the flow in a 90 gallon troph tank? 2 K3s or 1K4 or maybe even 2 K4s? any suggestion would be greatly appreciated.

There is a mod for the k4 that make them push a lot more water. Check out the SW forums.

I would mod the tunze nano stream cause it's smaller and the mod is cheaper. K4 also looks too big, IMO.

But Personally, if you got room under your stand for another canister then I rather increase flow with a filter over a powerhead.

Good luck dude.
