Review on Aquarium Biochemical SPONGE FILTER 30Gal by Kristi Wood

I recently purchased this aquarium pump and filter system in hopes of improving the water quality in my tank. Unfortunately, I found it to be completely ineffective .The pump is weak and doesn't provide adequate circulation, leading to stagnant water and poor filtration. In addition the sponge filter is difficult to clean and maintain. Thanks to my knowledge gained in practice, I now know that there are much better options available in the market. Save your money and look elsewhere for your pet supplies..
