DOSER OR CALCIUM REACTOR

[Bpb]

^^^^^ covered it. No feed pump needed with the deltec. Just the co2 gear. Though I haven’t personally had to supplement magnesium in years. Stays elevated through water changes. I go through about 10-12 pounds of media a year.

So the carbon doser is all I need with the deltec?

Doser for smaller tanks, Ca reactor to larger tanks.

It gets expensive using a doser for larger tanks, especially is you have lots of sps corals growing out. also It becomes tiresome mixing up solutions to dose all the time. A Ca reactor makes it much more economical and once you have it set up right for your tank, it is also less hassle with not having to mix solutions etc.
