that's how i evaluate the whole situation...initially i intended a CR, but the maintanence cost is too much, the pumps, the CO2 and the ARM...will definitely lose a leg if i run it in my pathetic tank...
so everyday do kalk top up...no need KR some more...shake shake shake, leave it for 20mins, top up...
i posted this question 2mths back, and no one can gimme a clear explanation...so i evaluate my pocket and decided to go SPSless and kalk top-up everyday...
