I'm wondering the same thing. Does anyone know???Replied by Catwoman (Somerville, Tennessee) on 12/11/2010
I have a fountain myself. If the charcoal filter is removed, you can place a white fleace product made for fish tank filters. It comes in a bag and looks like fine cotton. It does not effect the condition of the water, ph that sort of thing, but fitlers out small particles and debris. If you drink the same water you are putting in your cat fountain, it is good enough for your cat. But remember to change it often so that it does not become stagnant. Charcoal is used in fish tanks also. I know it does not effect the ph levels but I do not know about what effect it would have on removing the affectiveness of the acv.Replied by Debbiefudge (Brighton, East Sussex, Uk) on 03/01/2011
Hi, the easiest thing would be to remove the filter and use bottled water in the fountain, instead.
