Work out kalkwasser dosage based on alk consumption

[The Opinionated Reefer]

How do I work out how much kalkwasser to dose based on my alkalinity consumption?

I have looked at the reef chemistry calculator but it doesn't work out anything based on your current rate of consumption. I have 450 Litre tank but say it's only 430 due to rock etc and it is using about 0.1 dhk a day. It dropped from 8.5 dkh to 7.8 dkh in 8 days.

If i wanted to dose saturated limewater via a dosing pump how much would I need to dose daily to keep the alkalinity stable?

There are calculators that allow you to work this out for other products but not kalk.

0.37 liters or 12 oz or 376 ml whichever would be easier to measure would be your daily dose. This is using fully saturated kalk at 2 tsp of kalk per 3.7854 liters of of rodi water. I would just dose 16ml per hour if you have a doser.

Keep a close eye on your ph either way

How did you work that out? What's the formula?

I would love to say it’s mine but it’s from the website Randy recommended to me years back lol

Here you go, i used this one and it´s very accurate, i dose kalk every two hours via a doser, ph at night 8.1 and day 8.4/8.5 my daily alk consumption is 2.1 dkh
