yes, total water volume, Main+Sump. for Nano tanks, buying premium saltmix blends for reef would be the most practical/economical and trouble free way of maintaining water quality and essential elements. These premium saltmixes, although expensive, would weigh about the same as far as cost and effort in a NANO setup compared to dosing manually. Just do your water changes at "LEAST" once a week. I mean c'mon, how much saltmix would a NANO tank use every WC, a tiny bit, right?
