This has probably already been covered somewhere...sorry if it's a repost.
I live less than 100 yards from Copano Bay in Texas and I work at a shrimp mariculture facility in Port Aransas, TX. I can get oceanic seawater (salinity 32-35 ppt
) and bay seawater (salinity 25-30 ppt
) from a variety of sources, including Copano Bay. If you could get filtered and polished natural seawater, would you use it in your aquarium as makeup water?
