Up for sale is an Avast Marine K2 Kalk Stirer (larger one). I purchased it in November 2023 and have the original packaging. I will send pictures upon request. I stopped using it because I need the space under my tank, so I ran a water line to a brute can outdoors and just have my doser pull from there. Price is $200.00 shipped. Please pm or text me if you're interested 646 239 2887
Thanks,
Adam
