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!
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.
