Hi all, I have a planted 20 gal tank and my water is very hard(~300ppm). I purchased a Water Softener Pillow, but talking with a friend of mine, he said that it takes out the heavy metals but adds sodium/salt to the tank, which isn't good for the plants. I tested my water before putting it in, and it starts out as soft, ~75ppm. I'm guessing it is evaporation and then me adding more water that is making it more concentrated.
Any suggestions other than using distilled water during water changes?
