Can the 4 Part Red Sea Complete Reef Dosing System be set up without the Red Sea Doser. I love the concept, but do not love the price of the doser. Even though it would be pre programmed to dose accordingly referenced to your calcium reading. In a perfect world I would love the Red Sea Doser to go inline with the product, but that is a $650 start up cost, and just not in my budget for the reef right now. Just looking to get a cost effective all in one solution for my 80g... Yes I am considering Tropic Marin All for Reef as well, and looking at going with that one as well. Just looking at options. Thanks for your opinions....
