Does anyone use ATI Essentials? I'm trying to figure out my initial dosage based on what I have been dosing with the BRS bulk supplements. The instructions state: "For those who know their daily KH consumption, the optimal starting dose can be worked out from the following formula: 36 ml of ATI Essentials increases the KH value of 100 litres of aquarium water by 1°KH." That's all well and good, but they have 2 sets of dilution instructions, with one dilution being twice as strong as the other, and they don't say which dilution the formula applies to. My calculated dosage is coming out to almost exactly twice as much as I used with the BRS stuff, but I have heard the ATI still is a bit more dilute.
