I will be switching to dichlor, N2 and ozone shortly. I was using soft soak. Can anyone tell me if my filters that I used during my soft soak days (once cleaned with TSP) will be salvageable for my dichlor days ahead? I've read you have to throw them away because there is no way to clean them totally and they could foul up the new water and the dichlor system. I will throw them away if that is the case just wanting to check what you all have experienced or heard. Thanks.
