The water I am using is from an aquaculture lab and is pulled from the intercostal waterway in NC. They are pulling from from 30 to
50 ft deep and are filtering with drum filters, sand filters, canisters up to 1 micron, and UV. They have used this water for years with no obvious problems, but most are using it for indigenous species. Some have choosen to also bleach the water first before use, but the flow rate through the UV is pretty slow and is a large unit. The fish I will be attempting to breed are Pajama Cardinalfish (
Sphaeramia nematoptera).
