Ok so my levels have finally dropped so I want to raise my calcium from 415 to 440 and reef calculator says I need 195ml to do so of ESV b-ionic. How much can I add at once? If I do 1/3 of the dose it would be around 64ml, would that be ok? I just want to make sure I don't have this huge change in one day. For alkalinity I am assuming one dose of 30ml is fine. My tank is 125 gallons. Thanks in advance!
