a simple cartridge filter should remove quite a bit of iron and calcium, lowering your ppm to where you'd like it ... however, the iron and calcium, magnesium, etc., that you just filtered out, will have to be replaced with CalMag+, and you will still have to evaporate the chlorine out ... kind of a 'Catch-22' situation :wtf: ... I wouldn't worry about it, if your total ppm with nutes is in the right range ... my total ppm never reaches as high a level, as others I see in here, and my plants are doing fine :jointsmile:
