Fish Mox was reccomended for my cats by a friend who used it on his. I have a barn full of cats that were kind of sickly all the time. I got the Fish Mox, dissolved one capsule in one gallon of water everyday. In about a week, I noticed that most of the cats looked alot better.
If your pond does not contain fish then Fountec is a great product to use. This product is safe for pets that may drink from the pond but not for fish. Remember that fish and fish food add nutrients to the pond, which in turn feed algae. Donât add more fish than your pond and filter will support and donât overfeed your fish. Yet another means of algae control is a pond Ionizer.
