dKH - make up water

[aaronc]

Hi,

I am trying to match the parameters of my make up water to the parameters of my tank before doing a water change. I am using Ken Pro Buffer dKH. I do a 20 gallon water change but mix 10 gallons in 2 containers. The make up water after adding only salt has a dKH of 6.16 and I would like to increase it to 11 dKH. The instrution on the bottle say not to exceed 1/2 ml per gallon in a 12 hour period. I assume those instruction are for adding directly to the tank and that it would be safe to add more @ one time to the make up water. How much buffer would I need to raise my dKH from 6.16 to 11 dKH? Can I add it all at once?

Thank you,

Aaron

This calculator will show you how much to add. Dissolve it in some fresh water and add it all at once. Ignore the bottle directions which, as you suspect, are for maintaining levels.

Hi,

I've tried that calculator before, unfortunately it doesn't calculate anything for Ken Pro Buffer. The option is there, but the formula in the java code is not. Do you know the formula for Ken Pro Buffer dKH?

Thanks again,

Aaron

Oh, I see. It has it as a choice, but doesn't calculate. The exact data is probably not available. Just pick Seachem's Reef Builder for a good estimate.
