Do I really need a controller for my reef? I can’t afford an apex so I’m thinking about getting the reefkeeper lite plus. I have a 125 gallon tank with 30 sump! I run 3 Mars Aqua Black boxes. Can I even hook them to a controller? For flow I have 2 pp15’s and a 800gph voyager stream pump. I dose brs 2 part using a jebao doser. Help me justify getting this!
