People still using a calcium reactor?

After the skimmer, my calcium reactor is the best addition to the system. I could not believe how I ever kept a reef without it.

10 years and counting, set and forget.

BTW, no problems keeping Alk 6.5 - 10 dkh, currently running 8 dkh. For a ULNS, I get the best color and growth at 8 dkh.

Yeah I think it was one of the best things I changed about my tank this year. My alk has never been so steady, dosing never kept the tank this stable.
