so your adding the pool shock only while flushing or you add it to your resevoir every couple days or what? Things are looking good. Ya your 30 ppm of tap isn't to worry about much. Our water is about 60 ppm and after testing found out its mostly calcium which acts as a ph neutralizer. Ive been using the ro again since finding this out. Started to see the calcium build up once i started using foggers for humidity and was thinking dam if i'm seeing a white residue on things my girls are probably having a tough time breathing or using their stomatas properly. Nice looking roots,i'm pulling up a seat want to see this brotherhood og and your banana og.
im not the best at explain lol its a huge flaw and its very annoying :D.
but my tap is 150. if i was to go 2 weeks without flushing i would probably have about 200ppm of random nute build up from my tap. so to solve that i now just flush weekly. Since i flush weekly now i see no point to run any sterile after i flush i only add it in while i flush. and i do 4 grams per gallon. and then add 2ml per gallon which for me is about 100 gallons so i add 200ml sometimes more i have added 500 with no problems but i dont see the point.
i also have a drop line/feed line from my res that i drain out water by gravity over night before my main flush. always goes from 500ppm to 300ppm in about 12 hours.
i fill my system to the top and start my draining while i add my goods :P
i also add 80ml of micro 200ml of bloom .5 gram epsom salt and my pool shock mix
