I have a 220 gallon display that has been up for a year and a half, and I was thinking that I might purchase a calcium reactor. I have a Reef Octopus KS-100 kalk stirrer that I am using, but seems that I am hand dosing every other day to maintain dkh. I am looking for some calcium reactor feedback with different brands. Also what equipment would I need to purchase to set it up. I have 289 total gallons of water volume in my system.
