best reactor?

My atomic diffuser isn't really cutting it. In your experience what is the best inline reactor? I plan to run this on a 29 gallon tank so how long do you think it needs to be? Any links to the builds? thanks in advance!

Probably a cerges or rex griggs style reactor, there are several build threads in the DIY section.

how much do these reactors actually slow down your flow rate?

I'd recommend a Rex Griggs on a 29 gallon. Cerges is better but it's larger and slightly more expensive. It shouldn't slow down flow much because you're pushing the water through a larger opening. Just make sure you don't use any fittings that are smaller than your tubing size.

IF you have a canister filter (I know, not likely on a 29gal tank), I think that one is the best inline reactor. If it doesn't choke on the bubbles (some Filstars have that tendency).

AFAIK external inline reactors also need a canister filter as the driving force, unless you want to dedicate a separate pump.
