Kalk Stirrer Question

[milkman]

I have been using my Avast Kalk stirrer for a few months.

Based on the chart, I should be using about 2 cups of Kalk per week. I have been putting in two cups and watching for it to slowly dissolve over the week's time. After two weeks, it still seems like well over half the Kalk is still present.

I am pumping a Aqualifter pump for several hours a days spread out 15 minutes off, then 5 min on 24 hrs a day. Seems to be replacing my topoff water about right.

Question- should all the Kalk dissolve or is there a "spent" sludge left? I am using the BRS bulk Kalk.

i believe that your supposed to take out anything left over after a two week period. i think it's spent , so you have to take that out then replace with new kalk.

I use BRS kalk and it dissolves pretty good. More than half is way more sediment than you should have. I'd say try putting less in the reactor, it sounds like two cups is more than you need.

Good advice from both responders (sorry for the delay on my part!)

Some of the kalk will precipitate back out to form insoluble calcium carbonate, this is "spent" kalk that looks fairly similar to "fresh" kalk but IME is a little chunkier.

Try using a bit less and see if you get as much unused powder after 2 weeks.

Thanks for the feedback. I will go with one cup next time and monitor how much is used.

should you have to take the spent kalk out or should we be able to find a ( perfect amount ) certain amount so that you don't have to remove any kalk, and just add kalk? i ask this for reason of convenience. is this possible or should u always remove spent carbonate?

You will always have some which is extra and insoluble but it should not be much more than 10% or so.

i see this alot , not sure if it's a post error or am i read this correctly ? 10&#37?

I think that is supposed to be 10%...I see the "%" replaced with something else a lot in posts,must be a glitch in the software or something

this post just did the same thing,I had to edit it to fix it
