I've read till my eyeballs fell out, but it's always good to have knowledgable opinions. Planning my 90g reef, would you use a calcium reactor and in plain terms what do they do? Some sites are too scientific.

Calcium reactors keep your calcium in the tank at a constant level. It really depends on what corals you plan to keep if you will need one. If you don't go with corals that require a high, constant calcium level, regular water changes will be enough to replenish calcium. I'm sure someone else will come along with a more indepth explaination.

As travie said, it all depends on what kind of corals you are keeping, what kind of salt you use, and how frequently you are doing water changes. If you are going to keep a tank that is dominated by SPS and LPS corals and then you would likely benefit greatly from a Ca reactor, however if you are only doing a tank full of softies then it is completely unnecessary. With soft corals, the water changes will be sufficient to maintain the calcium levels.

if you are planning on lots of SPS and LPS i would get one, otherwise i wouldnt get it, wont be of much use
