When I had to adjust withthe 2 part solutions, it would be once a month or so.

Hi Brad,

Evaporation is about 7 to 8 litres per day. (90 gal reef plus 20 gal sump) I dose the 2 part solution daily...60 ml of each, plus the kalk....24/7....I have ajusted the the mix to 2 tea spoon per 1 gal of ro/di water.

Thanks Marco
