Can't speak about the BRS 1.1 Doser, but i can recommend their Dosing pump (50 ml per minute).
It is $10 bucks more than the 1.1, but I have dosed Kalk on my 38 gallon for going on 6 yeardused in conjunction with my old Reefkeeper controller.
hey guys, I am looking for a single dosing pump for dosing Kalkwasser on a 29g biocube. Thank you in advance
