Just curious on whether anyone has actually used them in a fresh water / tropical tank, exactly what is their purpose and are they of any bacterial benefit to the water quality.
Pro's and con's please.
Not sure if I have done the poll correctly but give me your feedback anyway, if you have used it in a freshwater tank, did you make it yourself or buy it ?
