Thank you for your inquiry and interest in our products. The product you mentioned is not specifically designed for use in fountains, however we do receive reports of pet parents doing so. Depending on the type of filter, most all remove all additives from the water, good or bad. I might recommend our Clean Teeth Gel or our Fresh Mint Foam as alternatives. I hope this helps.
