Re: Tap water and microorganisms in soil
You should check with your water district and find out if they use chlorine or chloramine. Chlorine will dissipate, chloramine will not. The stuff to get the chloramine out is available at fish and pond supplies Amquell is the one that comes to mind, but there are others. You can always do a "superflush" flood watering if you are afraid of buildup. I have an Orinocco in the ground that's 12 feet with a bunch growing, with two six foot pups. The rest were donated to a local school when they were smaller. I do a flooding watering every few months. Being in zone 9b (SF Bay Area), it stays in the ground year round. Your guy at the hydroponics store is trained to think in terms of closed circuit growing systems which informs his opinions.
