I found this thing at a pet store I was in that I thought was kinda interesting, they are these little tablets that you put in clean water after you change it (just like water conditioner). But they're supposed to fizz and bubble and help your tank with the ph levels and add a slime coating. I just thought they were kinda funny. Has anyone else ever heard or tried these things? They are called "Betta Buddies".
I have seen those. They basically do the same thing as any liquid water conditioner, but seem overpriced IMO. Why use a giant tablet that is individually packaged (bad of the environment!) when you can use 3 drops of Prime per gallon?
