Since this has been revived, I have a little update on my system. While I love the Essentials Pro, for me at least it's become very expensive to use. I dilute 4 to 1 and my daily use of #1 is 720 ml and for
#2, it is 840 ml so I go thru 10 liters of each pretty quickly and at 208.00 plus tax it's a bit pricey. When I first set up the tank and bought all of the equipment, i bought a full calcium reactor setup that i never used. So I have gotten that set up and I am slowly turned up the output of the calcium reactor as I slowly lower the dosing of Essentials 1 and 2. The dosing is still being controlled by the KH Director, so my plan is to lower the dosing to a minimal level, making up the majority of the demand with the Calcium reactor, but still allowing the Director to adjust the dosing to maintain the calcium and alkalinity constant.
