ocean water in reef tanks?

[Chipie]

I live right by the Atlantic Ocean and have used Natural sea water without any problems. Salinity is at 1.022 so i have to add a bit of salt to bring it to 1.026. There's quite a few reefers from the Maritime provinces that use it. Where i live, there's not much pollution so i just get mine off a fishing warf on Miscou Island(15 min from my house) Google map Miscou Island
