how should i upgrade too?

[suckafishtankcleaning]

so i am upgrading my koralia, due to red slime. i have a 29 gal, and right now i have koralia 2 that has 600 gpm. should i go up to an 850 gpm or 1200 gpm? i have sps, and candy canes in the direct flow of the pump.

anyone?? is 1200 to much for 29 gal its about 30" in length

I think the #3 will be plenty for that size tank

I run a total of about 1000gph in my 29. Since adding that much flow everything have been thriving. Of course, that's total on 5 pumps, not sure how 850-1200 from one source would be.

instead of one big one, why not just get at least one more small one?

[GuitarMan89]

1200 gal/hr seems like a lot for a 29 gal. usually you shoot for anywhere between 10-20 times you tank size, for a 29 that would be about 600 gal/hr. I also agree that two smaller ones are better then one big one. If you have too much water movement then some corals will not open all the way

i am trying to get rid of that bloody red slime, and everything that isnt a fan of alot of flow, has rock work around it break some of that flow, but the red slime grows right in front of koralia
