Review on SunGrow Underwater Aquarium Must Have Aquarists by Christina Snyder

later I used to think all sponge filters were more or less the same, but I was wrong! This sponge filter is really well built compared to similarly constructed filters from other manufacturers. The sponge itself is slightly larger and narrower than other brands. I was trying to save a buck by buying a cheaper angled sponge filter. Trust me, just buy a SunGrow filter instead!
