residue

i've had a batch of salt water aging on the front porch for several days. when i went to check on it this morning( intending to use it today) it had a funky gray film on top. it has been circulating well, and is in a brand new Brute trash can that i have used several times before for WC's. i recently switched my mixing pump to a rio 2100, rather than the old hagen 800, it works much better. the rio had been running a fountain in the pond, but the film doesn't look like pond funk, i wonder if it could be some sort of oil from the pump? it seems to stay on top. i'd rather not have to dump this whole batch of water, what would you do? maybe only siphon it most of the way down without disturbing the film? i remember this coming up some months back, but don't remember the discussion.

Did you wash out the trash can before you used it? I believe they use some sort of oil as a mold release agent when they do injection molding on plastics. Just a guess.

[GaryP]

If that is the case, my guess is that its a silicon oil and not really toxic. Its the same kind of oil they use in the pumps.

[blueboy]

yeah, i think i'm just going to try to avoid the film as much as possible, but use the water.

[GaryP]

When you are done, wash it out with a phosphate free soap and then rinse it out real well with a garden hose.

The film on top could also be a result of the salt. We have had some issues during our salt study and undissolve material in the various brands. If you left the top off the container, it could be dust and such.

Maybe try laying some paper towels on the top of the water to pick up whatever it is.

The barrel I bought was cleaned, but I got a light film also. The label on the barrel said 'Pork Parts'. :sick I can only imagine what that meant.
