I'd be very interested in know where you live in MN and what you define as "tap Water" ? I lived there for several years. For most of the state the water is very high in mineral content and most public utilities use ortho phosphates to keep the minerals in suspension so it doesn't coat the pipes. In addition seasonal rains cause fertilizer runoff resulting in nitrates off the charts. I know this because I reviewed the annual water quality reports all public utilities are required to report. Waterchanges only work to replenish the nitrates and phosphates used by existing algae. My only attempt using tap water in Minnesota resulted in an algae farm of biblical proportions.
