sea water?

knoxtnreef · 09/23/2021, 11:07 AM

has anyone used sea water in their tanks, if so, what was the salinity? I tested my local sea water, albeit not directly on the coast but a waterway 100 yards from it, and it read 1.015 so i'm thinking there was most likely freshwater run off from the storm we had a few days ago. at any rate, should it be treated if used and with what?

Many close to water do use it but there are adjustments to be made.

PaulB has done it since the beginning of time. The best advice I can give you is to get it someplace well offshore to avoid pollutants.

thanks, i read that as well. i dont have a boat so I most likely wont go this route...too many variables to factor. As you mentioned, testing the water just 100 yards from the shore had low salinity and runoff so I dont think the brackish water is worth the trouble to save a few dollars.
