Kalk stirrer

[eddiev0008]

Good afternoon I just purchased the AVAST Kalk stirrer wanted advice on how I’m supposed to use it with my ATO reservoir to pull RODI water and how I’m suppose to dose vs the fresh water that is already being dumped by my ATO? If I use both won’t my salinity start to drop? Please help:)

You have two options. Either use a separate dosing pump to push fluid through the kalk stirrer (either on a timer or via the control of the doser) which IMO is the best way to run kalkwasser, or you plug your ATO feed line into the kalk stirrer and let it push water through everytime your tank needs top off.

It's a fairly straightforward concept, but takes time to get it dialed in. Testing will be your best friend while getting it setup for your tanks needs.

I do have the apex and the apex DOS which I can use, but how would I know they I’m not pushing to much RODI with Kalk that will lower my salinity ? Is there a calculation on how much I should set up the DOS to push RODI into the steerer?

Apologies for the misspelling I’m on the road

Definitely could use a DOS head for this purpose. You have to have an idea of your evaporation to gauge how much you can dose. There isn't a set calculation that I am aware of since each tank will evaporate water amounts differently. Just start slow and work your way up. Your ATO will still make up the difference. In my instance I dose kalk at a 6ml/min via a doser 24/7 on my 100G SPS system full time and even then my ATO still has to run for top off.

Would this be a good schedule to start on a 160 gallon ? Mostly softies and zoes

I don't think you need to divide it manually like that.  Just put in the total amount over your 23 hours and the DOS will figure it out.

Thank you I’ll try it out

I'm getting ready to plumb in a kalk stirrer myself.  I'll put it on my DOS and may use the other channel of the DOS for Mg or other supplements.  Or maybe still dose extra alk with the other channel since alk is used for other things than just making calcium carbonate...
