Kalk drip Question

[Aquattro]

Chad, I use full strength kalk 24 hours a day. I mix 5g every day and hook it to my top off. You can drip it all day if you want at any strength you want. Air isn't an issue unless you mix up way too much. I think it's Randy Holmes-Farley that mixes his in a 20g garbage pail and it lasts for a long time.
Use whatever you have lying around for a container. Do you top off with a flaot valve regulary? Or have you been dumping your topoff water in once per day?
