I've done that with 33 gallon containers for raising brine
shrimp, and will be doing that with a pond liner soon. The
problems you will face is extreme salinity changes, and
lots of nutrients. Brine shrimp hold up well with this,
but doing a nice salt water fish pond could be a real
challenge.

Where the "nutrients" are coming from ?

Where I live (Chicago area) it would be extra-challenge
due to extreme temperature swings between winter-summer.
