calcium reactor vs dosing pump

I've heard about the phosphate issue but it was directed at certin brands. But I do believe that corals do utilize some po4.

You may be able to "cure" the media though I'm not certin about that

I used a calcium reactor every day for over 6 years without issue. Once you figure out how it works and get it dialed in, it is a very stable piece of equipment which will give you great results.

I use a dosing pump now on a small system (90G) and it is not nearly as reliable as a calcium reactor.

That being said, dosing pumps can be effective, look at Darryl V's tank.
