So I got rid of my Versa and I bought two simple cheap brs dosing pumps. I'm switching to ati two part for my 40 gallon. I also bought two Geeni smart plugs. The plan was to program the plugs to alternate turning on every hour for so many minutes. The thing is I don't know know if I trust these things to dose my tank. I have the same smart plugs controlling my reefbrights on the 40 gallon and the t5s on my frag tank. They haven't failed there.
