I'd be interested in hearing opinions of the pros and cons of each type of supplementation system, Calcium reactor based and 2-part solution based.

From what I'm looking at, if I understand it right, there's no reason to not go with a reactor. In a 2-part system, by the time you get done with the dosing pumps, timers, and making the solutions, you've spent as much as a reactor and co2 system.

Did I miss something? Are 2 part systems more healthy for the tank, or is the attraction that you can start out with nominal cost and then later get more sophisticated by adding the dosing pumps, where the cost of a reactor is all front-loaded?

Thanks!
