For reasons I don't fully understand, I found less scum in my reservoir by mixing with tap water, instead of distilled. With distilled water I'd get this fuzzy white film build up on the bottom of the macro fert reservoir. With plain tap water I don't seem to get this. The nice thing is that tap water is much cheaper.
