Hope that system works out well for ya! And yeah, that sucks about the Walmart water. I remember seeing you post about that somewhere, so I brought my tds meter with me. First place (Walmart) was 125ppm, luckily the grocery store up the street keeps their machine running properly. Its consistently 15-25.I'll keep the yucca in mind for bottom feeding since that is what i like to do now.
I gave up on rain water, have not seen a good hour storm here in 3 months now so i bought a RO system at the home depot for $165 after taxes. i hate to go RO as i loved rain water but i keep stressing about having to go to walmart and buy tap water from them since they don't service their RO stations there nothing like paying for 100+ppm water when you think you are getting 30-50ppm shit lol
