Flat worm infestation?

[Xtasia]

I wouldn't pour it back.. I'd consider it a small water change and put new water in.. what if some float back or they start releasing their toxins?

If you got some water mixed and ready you might as well use it.
If not granted 1 or 2 flatworms may end up back in the tank, But they just get vacumed up the next time. As for relesing the their toxin's it didnt seem to be a problem I used this method in my 10 Gal nano with no ill effect.
