Review on 🌊 High-Performance Dual-Density Filter Pad: Ideal for Freshwater & Saltwater Aquariums, Aquaculture, Terrariums & Hydroponics - 24x15 Inch Cut-to-Fit! by Christine Bryant

We have a large drooling male Pyrenean dog (left) who leaves drops of saliva in his bowl after drinking, which is why our other two dogs refuse to share a water bowl with him. Trying to keep the water bowl clean during the day was a lot of work, so we bought him a fountain bowl that circulates the water. Below the fountain, the pump is surrounded by this high quality aquarium filter (replaced regularly) that filters the water. Water when the pump pumps water through the pump and up. I have been using this dog bowl filter sponge since 2018 and continue to be satisfied.
