Hi. I am new at this and ya'll have really helped me a lot. I have quite a few venus fly traps and a few pitcher plants and I have been giving them only distilled water. They are doing great. I was just wondering about water filters. If I were to purchase a filter with a carbon insert and another filter with a fiber insert (the one that says it filters out minerals and chlorine), would this be as good or would some of the minerals still get through? They are set into a small water bog set-up beside my pond and during the drought it is getting pretty expensive filling it up with distilled water. If this is what it takes, no problem, but I was curious to know if anyone had tried these filters?
