Marineland Micron Filter Cartridge For Aquariums, Rite-Size TC, 1 Count

These are good filters and sleeves, I have two of the filters. They need to be cleaned out about once a week.

Solid replacement filters for my absolute favorite piece of equipment. Polishing filters are a god-send when my Engineer Gobies get to digging. The small filter takes care of the dust storm in just a few hours!

Product fits the Magnum 200- and was less costly than at the chain pet store.

Does the job

Performs well, do not clean with bleach. It causes the rubber to become melty and messy!

I love these filters! They keep water crystal clear and last a long time!

Works great. It really is reusable. I had to use a water hose to clean it but it worked!

While I love this filter and this particular micron sleeve, these are single use and obscenely expensive to use on a regular basis. It's a love/hate relationship. This filter works exceptionally well. But the micron sleeve is dead after one day. It's meant to work as a polishing sleeve, and it even mentions on the packaging that the sleeve will be dead after a single use. I've had some luck spraying it down with a kitchen sink sprayer, but I've found that the material breaks down and really can only be rinsed once before the integrity fails. I wish there was a way to replace the sleeve material. Or that you could buy bulk. It's a bummer that it only lasts a day, is single use, and it's expensive. I generally only run the micron sleeve once a week. I also wish the ends of the sleeve were recyclable. Considering it's a single use sleeve, it seems like a no brainer to at least make it recyclable. But alas, it works better than any other polishing filter/media I've found.

Great price for this item and quick shipping. I bought these to have a few extras on hand. They are extremely handy at polishing my tank water after a cleaning. I use them for 24 hours and then remove the Magnum filters from the tank until the next time.

Does not clear the aquarium water.
