Questions about flow

[digital-audiophile]

The nice thing about powerheads is you can adjust the direction of flow as your tank grows. I have lockline out of my return and hate it.. to much clutter for the little flow that comes out of it. I'm going to get it out on the weekend and maybe use a couple street 90's painted black.

I agree. Locline makes your tank look way messier then a powerhead. And if you just use 45's and 90's you are very restricted in flow direction. You could add eductors to spread it out, but I mean 2 or 3 eductors start to clutter up a tank as much as a ph. Plus like I mentioned its laminar flow as compared to turbular flow from powerheads. And I know I wouldn't want to run 3 large external pumps on a softy/lps tank?
