bleach at 1/100 still kills. Doctors will tell you that if you have a well balanced diet you really have no need for any suppliments. Suppliments are never the real thing. fish bones are a great form of calcium. Fish oils are a great digestive track lube. fish liver has tons of multivitimins. so how is fish a bad thing? fish are one of the main staples of water frogs. thats just common sense and fact. But "wipe out" is a good idea and i will try it. thank you for helping me with that.
