Top Fin Silenstream PF-S Refill for PF10 Power Filters 5.5in x 3.1- (12 Count) 1 Year Supply

this product that is supposed to be changed out monthly only lasts 2 days in my cleaned ten gallon tank, the indicator on my filter turns red to tell me to change it after one day.

Excellent quality and price for these filters. I have three fish tanks and with the pandemic and everyone getting fish tanks set up, couldnt find any filters and when I did the price was crazy. I was happy to find these. Got a good backup supply and when I run out will continue to buy these.

Cheaper then department store. Love it.

A cartridge definitely doesnt last a month. Maybe 2 weeks, if youre lucky. And for the third straight time, the box looks like it got run over by a truck.

We have difficulty periodically finding supplies of these filters. Amazon provides them quickly and at a reduced price.

I needed replacement filter cartridges and ordered a year supply. These were a great value and easy to install plus they came super fast. I have a 10 gallon top fin tank.

Just what I was looking for at a great price

Were going through our filters like crazy since were breeding guppies for a year long school project. The filter is unique since it lets us know when it needs to be changed with a little red indicator when it is dirty. it lasts a while when we dont overload the tank with too much food at a time. It was tiresome to go into the store monthly for these when we could just get this 12 pack and significantly minimize our trips.

Real thing, fast shipping. Great value for your money, definitely better then going to the pet store for them if you can wait Id recommend buying on Amazon.

tried to order cn-l filters ,i returned . thank you anyway dan
