I replace all my evaporation with it about one gallon a day and drip over night
with a homemade setup.
You may need to adjust for your tank but it keeps me at around 220 to 240
with out adding other additives.
I thank i may be getting close to my limit and may have to go back to
a little extra calcium soon as i have added a few SPS over the last year
and have a lot of LPS
