In my 33 gallon long aquarium I have 2 Aqueon filters for 30gal each. These cartridges work great collecting tons of waste. I replace them every 3-4 weeks with partial water changes. These cartridges come out dripping with waste, so it works just fine. In addition, I have a medium size sponge filter on, so the water is clear.

Efficient Packaging

It is the exact filter for my aquarium equipment, It came with plenty of filters and they were packed in a box that minimized waste.

works well, rinse before use.

using these for years, changing 1x a month. easier for me to just rinse new ones and replace rather than messing with own filter floss etc. pay for the convenience

This filter took 1 week to clear the tank entirely. I purchased a 9 pack, the first one cleared 90% of the junk in 5 days, the second one has been working for 8 days. I suspect 9 filters will last me 3 months, excellent value in my mind.
