H2O Dissolved solids

[SOG420]

I need a source of H2O that has little to no chlorine to keep my myco reefs alive. In order to by distilled water and use this everytime I water it costs $12 a week. I was wondering if a brita filter might help. After useing one the ppm of my reg tap water went from 130-150 to @60. What I don't know is how much chlorine it's removing. Any suggestions?
