I sell anywhere from 200 to 400 of mixed saltwater and 100 to 300 of rodi water every week. We decided not to sell Ocean water because it's collected from the docks in Monterey. If we were down south I would have no problem using natural seawater.
Not to big of a issue, the white or neutral wire ends up on the same ground bus as your ground wire in the electrical panel. The ground is just extra protection.
Hey if your doing a group buy it can get you the same stuff for about the same price depending on how much you want. No shipping cost and local pick up. Thanks
I ran in the same problem, I couldn't find metric pvc anywhere. If your in a rush you can use a piece of tubing to adapt from metric to standard. If not your best bet is to order it.
