Many of my buffers say that I should not exceed x amount of it per 24 hour period. For instance, if memory serves me correctly the calcium buffer says do not exceed 20mg / 200L per day.
I assume this is because of the affects on the fish, corals, etc.
What about on water that I am preparing for a water change? My tap water is typically very low on KH
and the PH
is right off.. is it okay to buffer them with as much as would be needed to get the various levels correct, in one treatment?
