We use these on all of our aquariums. They do an excellent job. The tanks look great and the cartridges are easy to change. The big package is a good price and ensures I always have replacements in stock when I need them.

I absolutely love these filters! They work great, take 10 seconds to put together and put less waste out into the environment. I will never buy pre-assembled filters again. Do something good for your fish AND the earth.
Cheap and easy filter cartridges to make.

It's easy! You have to put the charcoal in the bag and insert the bag into the plastic holder. That's it! Definitely worth it for the price.
