Kalk dosing....

[Canadian Man]

This reply may be long winded but should help you some.

Background:
I have a basement sump (75G) with 2 Instant ocean buckets hooked up to a float valve that is used for auto top up of the sump. The buckets are above the top trim of the tank so to the float valve is gravity fed. The air line tubing is aprox 2" off the bottom of the bucket.

Original dosing method;
I used to mix the kalk in the buckets, using ball's pickling lime. The 10g would last about 4 days and then I would add 10 heaping table spoons per bucket, then add the water and I was good to go for another 4 days. This worked well but if the sump water level was a little low at the time of mixing then the cloudy kalk would enter the tank. I would also have to clean out the bucket once a month to keep things fresh.

Current method;
I got this idea kinda from another canreefer(dez)
I am using an old kent plastic container that was used for holding carbon. It probably holds about 2 liters of water or so. I attached airline tubing to the bottom of the container and to the lid on top of the container. This is where the water enters(bottom) and exits(top)of the container.I filled the container 3/4 full of piclking lime and put it inline between my top off buckets and the float valve. So did not change much of my set up except only fresh water is put in the IO buckets the water enters the bottom of the kalk container is forced throught the kalk exits out the top and goes to the float valve.

I am very happy with these results and enjoy this set up more that I did mixing kalk. It is much neeter and seems to work well.
No the kalkpowder does not come streaming out the tube. The water above the kalk in the container is clear.

hope this helps ya some
cheers
