Dosing Kalkwasser

[RaptorMan]

Hi Reefers,

Planning to dose Brightwell Kalk +2 on my 20g Nano tank. Never dosed and right now figuring out how much my tank evaporates. Could I make a one gallon batch of Kalk and put about 600ML in dosing container which may last me for 2 weeks without losing potency? How long can you store Kalk and best way to do it?

Thanks

if you are just mixing to full saturation it will be fine for a long time as long as you keep it in a sealed container to avoid fresh oxygen. I used to mix up 60 gallons at a time for my system that would last me 2 weeks.
