How to connect Neptune ATO to TLF Kalk mixer

mkoenig · Dec 20, 2023

I am looking to upgrade my top off system. I am currently using a float switch and a powerhead pumping RODI water from my reservoir through my Two Little Fished Kalk mixer and then into the sump. Tubing I think is maybe 1/2" tubing? I want to replace the powerhead with the Neptune Systems ATO but it uses RODI tubing.

Looking for advice on how I can still use the Kalk mixer with the ATO. Seems like I need a way to convert RODI tubing to a 1/2" tube?

Any help would be greatly appreciated.

You have a continuous flow through your kalk reactor now, don't you?

When you say powerhead, do you mean dosing pump? If not, then I don't fully understand how your setup is working

Be careful not to overcomplicate something that works for you though.

No it is not continuous. Powerhead in the top off reservoir is triggered by float switch when tank is low and pumps water through the KW reactor and into the sump of the tank. I do not put KW in the mixer very often but that is not what I am asking for.

Basically was looking for a John Guest fitting for a 5/8 tube to RODI tubing.
