R/O or not
I am going to be keeping dwarf crayfish with my plants. I have a very heavily planted aquarium. I live out in the country and use a water softener. Should I get a r/o-di system. I have had my well water tested and they found nothing harmful to human beings. Matter of fact, due to the lair of sand in my area the water is way below normal contamination levels for my area. I would really like to hear some opinions and advice on this matter.
