The tank I use the Chihiros Doctor with is a community tank. It has all sorts of fishes in it.
My Neo Tetras always have white spot diseases. And my Golden Barbs are also plagued by occasional outbreak of cysts.
After deploying the Chihiros Doctor, I have witnessed a significant drop in white spot diseases among my Neon Tetras and the cysts on my Golden Barbs never return!
And recently the coil is no longer producing as much “fog” and the white spot diseases is returning with a vengeance.
