Left over Kalk?

[spankey]

I was curious about kalk? I have a 5 gallon top off jug that I fill every 3 days. I add kalk regularly but am curious if the left over powder on the bottom has any left over effects? Is it useless? I wouldn't think so seeing how kalk reactors hold a certain amount of kalk and you don't change that out for about a month......

My container is nearly sealed except for a small pin hole in the cap to allow the dosing pump to pull water from the jug without suction and collapsing the jug.

How do others add kalk to their top off jugs? Do you dump out the left over on the bottom so many days or weeks?

Just curious...
Thanks

I mix in a 55 gal drum and dump my old out about twice a year.

I don't know if it is a problem or not. I use pickling lime, btw.

I'm with Steve. I clean mine out about every 6 months or so. Theres nothing bad about the precipitate in the bottom, I just clean it to keep things flowing nicely.

kalk is not completely soluble. the "precipitate" is kalk.

Randy has an article about precipitates and covers the stuff at the bottom of your alk container. It is vague in my head as I read it some time ago. The stuff in the bottom is pretty much insoluble. I don't know, I haven't emptied mine but it doesn't seem to be getting any deeper. It reacts with vinegar. I usually add vinegar now to boost my kalkwasser.


Nothing I said probably helps but you should look up the article and it will probably answer the question much better than I am.


You'd think I had been drinking or something.

i have a 10 gallon plastic bucket that i fill up with RO water and a cup of kalk. mix it twice a day on a timer for 5 min. every 4 days or so i refill it with RO water only. every 4 refills i add a cup of kalk. once i forgot to add kalk too many times and the water was almost clear during the mixing. water can hold only so much calcium thats why you have so much precipitate. but keep adding fresh water and more and more will dissolve till you wont have any left. i leave it in there. why waste it. i have yet to clean my kalk bucket. the precipitate is still kalk, it doesn't dissolve because its something else. if there is impurities, im sure they will accumulate over time. it would be wise to clean the container out completely but not too often that your wasting kalk.

ryan is spot on! the precipitate at the bottom is just kalk that has not gone into solution! as the water level in the top off container subsides just add more RO and that left over precipitate will dissolve into the RO!
