Help ato line blocked from kalk build up.
Im doing kalk dosing thru my ato system Im using a float valve and a aqua liter pump tonight I discover the line that goes in my sump is blocked.

So what can i do that this does not happen?

I had the same problem so I switched to the blue silicon air tubing. Don't know what type of tubing you're using now, but the kalk buildup doesn't seem to stick to the silicon tubing as much. Plus it's more flexible and easier to swish in your fingers when trying to remove the build up. Also, if not already doing so, make sure the tip of the tube isn't resting on the very bottom of the resevoir (where all the deposits settle.) I started suspending my tube about 1.5" from the bottom of my resevoir and the tube stopped getting blocked.
