Top Fin Silenstream PF-S Refill for PF10 Power Filters 5.5in x 3.1 - (3 Count)

I add this but it seems like these products never really do anything extra for fish tanks.

To be honest with you these filters keep the water clean just a few days. You have to buy polish pads and wrap around the filter in order to work good.

I liked everything and disliked nothing. I used it for my fishies.

Fit

Excellent purchase.

Will order again

Recently learned after purchasing these and doing more research that replaceable filters are a scam. They completely throw off the balance of your tanks parameters. The green/brown gunk that builds on the filter is good! Its beneficial bacteria! Research and invest in a sponge filter instead

I have a 10 gallon tank and these are perfect!

Great

They dont last as long as advertised. I have 15 small guppies and the filter only lasts 2 weeks before the water starts to get cloudy.
