My tank had Hydra.  After 1 treatment and 2 days, my tank no longer has Hydra.<br />This is how I used it for a 40 gallon freshwater: Took an empty water bottle and filled it about half with my tank water.  4 pinches of the bendazole, cap back on and shook it up like crazy. Dumped it in my tank. Hydra were almost all gone the next morning. By the second day they were all gone.  Then did a 20% water change 2 days in a row.  No harm to my Shrimp, Snails or fish.
