They work for Months. Perfect fit in my penguin filters I have used since 1990! This filtration system last for years I have 125 gallon saltwater water tank and an aquariumenthusiast for years. Plus Chewys can’t be made on price, fast delivery and accuracy. Hundred percent every time.

The replacement cartridge is great

Like I said the replacement cartridge is great. Fits perfect easy to change. The bio wheel is junk. That thing doesn’t spin for more than 10 times then you have

Like I said the replacement cartridge is great. Fits perfect easy to change. The bio wheel is junk. That thing doesn’t spin for more than 10 times then you have to adjust it and doesn’t sit in the holder correctly. Just saying I could be doing something wrong but I won’t buy it again

THE BEST FILTERS

I have been using these filters for over 45 years and have tried others, but these are by far the best and easiest to change and use. I never change them until I see the water running through the "overflow channel". Then they are full. It saves money. I have many tanks and I will always use them. They are great.
