morning and night to keep up with the SW
demand. Water doesn't "sit" around at most LFSs that sell it.
Also not sure about what nasty stuff you are talking about.?
It's great that your store uses ro
water and has a high turn around of it. That's something that you should advertise. I've never seen a chain store sell SW
in anything other than what looked like pre-sealed milk jugs (4l types or 1G types). None of the SW
only places around where I live sell pre-mixed SW
As for nasty stuff: water kept for a prolonged period without proper agitation could end up with unwanted algae, ph can get thrown off, salinity can change. It would all depend on how the place was making that water, how they stored it, how long they keep it, what the water is kept in, how frequently they change ro
filters, if they even use ro
water, or if they always use the same salt mix.
