2 part question but its about kalk

[mlivvy]

I have an avast kalk stirrer and I have it setup to drip into the return chamber. My ATK stopped working and I discovered that my sensors were encrusted in kalk sludge. I'm looking into moving the kalk hose and I have 2 possible solutions with questions.

1. My sump has an open drain hole. Can I dump the kalk into that drain? It will work its way back up into the filter floss box. Eventually i'll be readding a klir roller and I don't know how the kalk reacts with filter rollers or floss.

2. I was thinking of running a line up to the DT from the dosing pump that feeds the reactor. Would that even be possible with the 1/2" outlet on the avast stirrer?

Limewater/kalkwasser should be slowly added to tank water through the air. An underwater line can cause a lot of precipitation where the two waters meet.

I personally wouldn’t overthink it and just discharge in a high flow area

Thank you

The drain has a few inches of before the water line so it won't be underwater. I was just concerned over the kalk going into the floss.

and yeah I’ve had kalk screw up optical sensors, clog up lines, et I won’t use optical sensors with it anymore opting for float switches et.
deposits can collect like stalagmites or whatever…won’t hurt to have the drip line near your return in the sump

And like stalactites!

oh it’s way worse than that….my spell check sucks and I hate fighting that thing with my bad eyes…I hit edit so often it’s insane …pardon me OP

No problem. I had to google both words. ;Dead

To keep the drip line in the return i'd have to go with float switches and ditch the atk.

I did find someone in this thread with the kalk stirrer output going into the drain area of the sump so I guess it could work.

I'm still not sure I understand the setup, but if the dripping kalkwasser is hitting filterfloss that sticks up into the air or is about at the water surface, that will be bad.

Kalkwasser needs to mix in quickly. The tank water in filter floss will not allow rapid mixing and there will be a lot of precipitation taking place in that area.
