How to Setup Flow

[fade2black011]

I have the Rapids Pro system in my 30 Gal long. I don't get much flow and am starting to get a small algae outbreak, so I am thinking of adding 2 Max Jet 600's with Sure Flow kit or possibly 2 Koralia 1's. Is this a good idea? Overkill or not enough? Currently, it is just a FOWLR tank.
Thanks,

I would go with 2 Koralia 2. That I think you you will be good.

+1 the number 2 korilla is much better for your size tank.

For $4 more I can get 2-Koralia 3's... Would this provide too much flow? It is a 36" tank.
