Hello, i was curious as to who uses a kalk stirrer. I was running kalkwasser in my ato on my last tank. I upgraded tanks and cant use it in the new setup. So i wanted to look at a stirrer. Any recommended brands?
Who uses kalk stirrer?

Have you looked at the Aquamedic Kalk stirrer KS1000?
I used it for my 24G but found Kalk is hard to dial in as the solution gets diluted over time as you used it inline with your ATO. I now used 2 part from BRS. It's not that expensive and can last a very long time. You just need to invest in two dosing pump and a timer or controller to dail in your Alk. The cost will be similar to KS1000 and you have more control.

Well not sure how big your tank is our whether you plan on using kalk as a primary source of for CA and Alk replenishment. If you are planning an sps dominant tank I wouldn't use alk as the only source, its difficult to dial in and usually will not keep up with the demands, and becomes dependent on your evaporation rate.
But just focusing on the recommendation for reactors, I have had both the GEO Kalk reactor and the Avast K1 Kalk stirrer and you really can't go wrong with either. GEO is built like a tank and they make great calcium reactors as well. I wasn't a huge fan of maintaining the maxijet in it, but it was a great reactor.
I also have the Avast stirrir and its great as well, slightly different than the GEO, still built well, it works great and if you want to have some fun and are a little handy you can save some money and buy the kit and build it yourself.
The two reactors have slightly different delivery mechanisms as well, so that is something to consider.

I had a 60g cube and was using 2 teaspoons per gal of water in ato. It kept my numbers stable so i liked it. I upgraded to a 160g which will be mixed reef. Not a lot of sticks. I will look into the GEO and avast

The GEO is large, and its pressurized, meaning you feed the reactor and it forces the effluent out, while the avast is not. The avast you feed and it flows out the top fitting via gravity, so I believe it would have to be slightly above your sump. The avast as two sizes as well, the K1 is much smaller than the GEO Kalk reactor.
I can tell you this I have a 100G total water volume system, sps dominant, and when it is firing on all cylinders, kalk alone can not dent my needs. Although, there are people who use solely kalk in there tanks. Every tanks demands are different.
You would probably be better off with the avast, or looking into two part, with dosing pumps. But that is another set of equipment, you would need timers, or a controller like an APEX. But if you dose is low enough you can manually dose two part, or use kalk and dose two part to make up the difference.
