IMO chloramine will set back microorganism activity in a living mix. Outdoors is more tolerant, but in containers, at very least,it won't be appreciated. I have a high ppm well water running 7.2 with no chlorine/amine but I find that in containers, my soil does build a highish ph. Seamaiden, you let the soil do its 'thing' and all is well? I have issues with Mg and Ca salt buildup on the upper soil layers (which dry out most) after a long cycle. If I don't put the top 10% of the used soil in the compost/soil heap, after 2-3 indoor cycles, alkalinity and ph get into lockout deficiency territory. I have to use rainwateror melted snow to control the buildup in containers, any tips? My ppm is in the 240-280 region. I tried using municipal town water, let air out for 4 days, showed 50ppm very low to no chlorine and burnt my plants! I don't think chloramine showed on my tester, and I believe thats what torched my girls, I'm not to keen on RO or softeners.
