I lucked out because my water out of the tap is very soft. KH1, so it worked its way out nicely. They will give you replacement bags, although I am not sure if that helps because you may go through it again. Everything has its issues. Soilmaster Select seems to makes your pH tank, ADA AS sometimes causes brown murky water and lowers the kH <desirable for some> and Eco, causes temporary KH spikes. It is always something. Know that continuous monitoring and water changes will alleviate the situation within a couple months.
