i read this article that gave me the idea:

but in the article, one thing doesnt make sense to me. the author says:
As I explained earlier, I intended to use the LiterMeter III to dose a two-part supplement, as well as replace evaporated water, on my 40 gallon reef aquarium. The total water volume in this system, including a 15 gallon sump, is approximately 50 gallons. This system loses 4 gallons of water each week to evaporation and requires 30 ml of each component of B-Ionic on a daily basis to maintain adequate levels of calcium and alkalinity. To accomplish my goal, I added a week’s worth of each component of B-Ionic to separate two-gallon vessels and filled the remainder with deionized water. This also dilutes the supplements and lessens the chance of precipitation or spikes in pH. I set the daily total for each pump to “one liter.”
how come he set the pump to one liter? that is a lot of bionic he is adding a day. or maybe he diluted it to the right amount and then added it to the two gallon vessels with extra stored somewhere else.
