I'm wondering if there are plans to release a 3 or 4 pump (or larger) DOS module. Every other pump on the market that I know of has at least three or four pumps, and most people dose more than calcium and alkalinity. I understand the utility of a 2-pump unit for automated water changes, but really, most people would like more than two pumps. And before you say "just buy two", consider that the cost of two would be significantly higher than other options. So, is this in the works?
