great for keeping water clear

5 out of 5 stars

great for keeping water clear
I use these as seen in the picture to help keep may fresh water tank water clean. I have used them for years- I will take it out and rinse and repeat until the sponge runs clear about every month and a half. After about 3 cycles I usually replace it with a new one. These are great

    I have a sponge filter I bought off of Petsmart, ‘Topfin Sponge Filter’ and unfortunately they don’t sell sponge replacements you have to buy a whole new filter and I didn’t want to do that. But these I found work so well. My fish tank has crystal clear water and it’s doing the job just was well as the original sponge. I love it!

    I needed a replacement for my 55-gallon tanks. They are different from what I had before. For me, it sucks up tight after about a week's use. The surface is smooth, not open-cell material. I will keep looking.
