Kalkwasser help in my 25g

[jhaggerty1990]

So Ive been dosing 2 part but wanted to switch to kalkwasser bc I cant get above 7.8 pH. I have a 25g tank that loses about 1500ml a day to evaporation and .5 dkh per day. I bought a 5000ml container to mix the kalkwasser. How much should I add to the container and whats an estimate of how much kalk I should be adding as to not overdose at the start?
