I've been using these filters for our small fish tank for over a year now and they work great.

The aquarium filter works well to remove scum. I rinse the filter with my sink sprayer occasionally to clean it off and use it until necessary replacement.

Quick and easy replacements. Make sure you clean your actual filter from time to time before you replace with the replacement cartridge.

I bought small beta tank at Walmart but they don’t carry media for those filters. Amazon was the only place I was able to find this size! It fits and works for my son’s beta fish. Will buy again. Reasonable price and fast delivery.

Es la 3era vez que las compro y me son muy útiles para la pecera del pez beta de mi hija, al cual le cambio cada 3 semanas el filtro.

I have two paludariums with very small. mini pumps. These pumps are great but do not have a filter system. I bought these and created a super simple filter for my waterfall! I took a mini plant pot (1-2inch) that came with some of the little plants. In that pot I nestled one of these mini filters at the bottom and then placed the pot below the waterfall where the water comes off the rock. The plants hide the pot and the filter helps to keep the water clean! These are perfect, easy to use, and easy to change! While I may not be using them in the traditional manner I feel these are fantastic if you have an unusual project that you need to create a filter for.

estos cartuchos le quedan perfecto al filtro que tengo en una pecera de 4litros con un pez betta, deja el agua cristalina hasta por 4 semanas y no deja que se haga moho. Me parece excelente conseguirlos por amazón, sobre todo porque están a buen precio, duran mucho y en otras tiendas de mascotas no hay.
