Filtered Ocean water and mixed saltwater

Hey guys...Im planning to buy water from the LFS. My question is the LFS im going to carry filtered ocean water, in the future if i want to go with mix salt water for water changes, will it hurt my tank? Thanks for the help, im pretty new and just want to do it right.

 

I have seen it but have not heard of anyone use it yet.... I plan on the wait and see approach.

 

I use "filtered" (UV treated) sea water in my tank. Critters love it and price is right for me.

Used for initial fillup and now for water changes. Get fresh RO/DI water from LFS for top offs.

Only problem is water this far north (Seattle) tends to be a bit lower in salinity then what "tropic" water is. Need to watch that.

Adjust by using seawater to top off first couple of days after a major water change.

Just make sure coming from "reliable source."

Rgds,
