Cerges Reactor questions!
Planning on perhaps putting together a Cerges reactor to diffuse co2.
Couple of quick questions;
1) I've seen folks use bio-balls in them, along with the Rex and other reactors. Is there any genuine benefit to this?
2) I've also seen folks use powerheads, in some form, before or after the reactor. I'm assuming to up the water flow. What's the story behind that? Seems like an extra spot to potentially leak and I'm not sure the reactor is really going to reduce flow; but figured I'd ask before I put something together!
3) Recommended 'water filter' (to use as the body) for a 29g tank fed by a Cascade 1000? I was thinking just one of the smaller ones ought to be plenty; but as the Canister is a relatively big one, thought I'd ask!
4) Might not make a difference, but, for grins I'll ask. Is the spray bar or 'direct flow' discharge (powerhead style output) a better option for the final output? (The Cascade canister includes both options; I generally use the spraybar)
