Dosage of Melafix + Pimafix

No. It is a waste of money and not proven to be of any value. Tea tree oil is a useful homeopathic treatment for many things. I just never heard of anyone receiving a benefit when used on their fish.

You can use the full dose of both together with no problems, you don't need a half-dose.

These are not homeopathic treatments, that's a different thing entirely.

Yeah, I must agree with Anna's comment about it not being Homeopathic. Homeopathy, defined as 'a method of treating disease with small amounts of remedies that, in large amounts in healthy people, produce symptoms similar to those being treated'

Melefix actually has tea oil in it, and is used in pesticides as well as medical treatments of humans. http://en.wikipedia.org/wiki/Tea_tree_oilhttp://en.wikipedia.org/wiki/Tea_tree_oil#In_aquarium_fish
