I just bought a betta and the guy suggested that I use bettamax. I used the bettamax on the water which turned green (from my searches on the internet, I believe this if normal.. I hope). I was wondering whether or not I should use the bettamax all the time or can I simply put in regular spring water with no treatment. The green-ness of the water is a real turnoff and I would like to be able to see the beautiful colors of my fish. I know that the bettamax is supposed to get rid of diseases, but constant medication can't be good, can it?
