have a 30 gallon tank
i plan to dose in ato

i have it set up so im dosing about .08 gal each hour
is this a safe amount without raising the ph to high

im also mixing 2 tsp per gallon

Yes, that would be fine. Is the evaporation really that high, or is that the pump rate and then the ATO controls it from there?

thanks for the reply Randy

its kinda funny, imdosing kalk in a makeshift way. i have a powerhead hooked to i timer that comes on for one minute each hour. each minute its set to dose around .08 ( i measured in a gal container) then i have a flote valve that shuts off wen the water level is at a certain point.

i probly get about a half gall evaperation a day.

sorry for the long response but its kinda weird how i dose kalk
