3 part or Ca Reactor

[Dez]

I have never used 2 part, but have been using a calcium reactor all along. A calcium reactor is expensive to start out, but after that it's pretty inexpensive. I find it maintenance free. I have lots of stony corals but it's still maintenance free. I know many of the hobbyists are on 2 part, I'm not sure how often you have to mix and refill etc... I basically fill my reactor about once every 4 months and I only have a 10lb C02 bottle but that lasts about 6 months. I picked a reactor that was super easy to refill to make filling easy, it has a screw top, so no thumb screws to deal with. HOpe this helps.
