Review title: Kordon Fish Protector
Product review: This stuff is a big help in fighting fin erosion when your fish are under stress from illness. Kordon claims on the label that the polymer coating absorbs methylene blue, malachite green, nitrofurozone and antibiotics like tetracycline and acts as a carrier for the medications. My own experience in treating velvet is that without this stuff I lost a veil tale to stunningly rapid bacterial fin erosion down to the roots, and with this stuff, fin erosion halted and I did not lose any of my other fish. And with an early enough application in another tank, there was no fin erosion at all when that horrible gold dust had to be treated there. (If you experience velvet, keep in mind that it is exceedingly virulent and take extra precaution not to spread it to other tanks.)
