Reactors for a RSR 425XL

hawkbait · Oct 19, 2020

Hey all,

I've been running my RSR 425 for about 8 months now and want to add a carbon reactor (to get my carbon to work better than just filter bags) and for phosphate removal, also thinking about doing calcium at a later date. Should I go ahead and get all three and not run the calcium.

I was looking at one on amazon and getting multiple of them, I'm not sure if it's a good one or large enough for my system. What type of system should I be looking at is basically what I'm looking for.

What you're looking at is a hang on the back reactor. Since you have a sump, I would advise against that. I personally would get a dual chamber reactor to run from the sump if you're looking to control water clarity/impurities (carbon) and phosphates (GFO). A calcium reactor is a completely different and much more complicated animal, and won't address either. It all comes down to what you're trying to accomplish.
