These are exactly the right size and shape for my small tank. They work well and are easy to install. They last a few weeks as long as you upkeep your tank. Overall, they help my tank stay clean and filter the debris from feedings, etc..

I bought these as a drop-in replacement for a Petland fish tank; these are half the price they charge and are the same quality. It fits perfectly, with no cons and all pros so far. I'm on my third box and don't see a need to find another brand. used with a Topfin revival waterfall desktop fishtank
