kalkwasser question
 

hi

i have a question want to ask you guys
i'm so tired to mix kalkwasser everyday
so now i want to mix 20 gal instead of 1 gal per day
and use it for my next three week
my question is after the kalkwasser mix with water
how long it can last or it doesn't matter how long after i mix them

thanks

unless your storage/dosing container is airtight, you may want to look into using a kalk reactor instead.

3 weeks is a long time, and as the kalk gets in contact with co2 it will precipitate out of solution.

HTH.

There is an article on the RC magazine about this, the author claimed that kalkwater stored in a container with a lid would not degrade over time, I used this method for a while (garbage can full of kalkwater mixed up every couple of weeks) however when I got my kalkreactor I noticed higher pH in the tank and higher calcium level in the tank.

I mix kalk in a 25 gallon drum and slowly drip it in. It lasts me about a week and does not degrade over time as long as I have the lid on. There is a test done on Reefkeeping magazine that proves that covered kalk (not anally airtight) lasts for over a month.

Connection to the RO/DI to fill it up.

Hope that gives you a few ideas. :biggrin:

How about a calcium reactor as another idea??

Good pics Ben. :smile:

As mentioned, Randy did some studies on RC and showed no loss in calcium content in his large rubbermaid storage tub for kalk, even afetr a month or more. Just mix in some water when low and throw in a cup or kalk now and then. I think he cleans it out a couple times per year.

Many of us now does our kalk that way. Bens pics show a similar set-up. Randy even argued the non benefit of running a kalk reactor versus the tub method.

thanks guy
