Yes you would. It then gets really expensive, that is why I went with the 3-way Aquamedic doser. I use it for B-ionic two part and water top off.the liter meter description says one internal pump and 2 optional pumps, but it also says 3 programs for one pump. Would I have to have the 2 optional pumps if I want to dose 3 things?
The PrattDoser is also a good system Leslie.
