Just a few things I have dealt with with fish tanks.

Bringing in "living water" is good because you have an instant ecosystem. Just be aware though that you are bringing in things, ALGAE, that could be a problem once it gets into an ideal environment in your tank.

I tried it in the past with freshwater tanks. We will just say I had some things growing in there I didn't want.

If you want to have all the plankton and sorts of the estuary an under gravel filter should be okay. If you go with a big good external canister type filter you will filter all the little critters out.

I have a big canister with a good filter drum on my large tank. It keeps the water crystal clear because it removes everything. I had problems with unwanted worms due to inadequate filtration in the past.

You may want to keep an eye on salinity and frequently change some of the water with new estuary water because the water gets saltier as water evaporates and leaves salt behind. Even my freshwater tanks increase in salinity when I don't keep up with water changes on a regular basis.

I have found that with frequent water changes the filtration didn't have to be a good and with better filtration the water changes could be more infrequent, but still neccesary.
