I suppose I mean a deep clean, want to know what the best product to use is.... Vinegar? this tsp stuff or cascade, don't have a dish washer, but I do have a bucket :-) I'm thinking I want to try to get some possible calcium build up off? My filter always looks so clean when I take it out, hardly anything in it, it's only 2 of us using it once or twice a week. PH and Alk, is good but my calcium always seems high, not sure what to do about it but thinking I may have calcium or mineral build up on filter and I can't see it?
