## Questions & Answers

**Q: Is this to use in replacement of tbe carbon media?**
A: This filter media is designed to be used by itself, without the carbon media container or carbon.  Its purpose is to polish the water so it will pull very fine particles out, causing it to clog rapidly.  Be sure to follow the cleaning instructions for it to get multiple uses from it.

**Q: When do i replace the micron polishing filter?**
A: It’s interesting. The micron polishing filter works great, but for only about a week at a time. I didn’t know this when I started using it instead of my Charcoal Filter system. I finally figured out that I needed to clean it at least once a week if not sooner. I’ll probably go back to the original filtering system with Charcoal and only use the Micron filter if my tank becomes cloudy. I have a 55 gallon take and 3 Micron Filters and I now clean 2 of them at a time with a 3 to 1 water to bleach. Example: 700 ml bleach to 2100 ml of water.

**Q: What do I use to clean the micron cartridge**
A: I soak it overnight in a 2-gallon pail of water with 1 cup of Clorox added to the 2-gallons of water.(you have to weigh the cartridge down or it will float) IMPORTANT ... I then empty the pail and soak the cartridge in a 5-gallon bucket filled with 5-gallons of plain tap water for FOUR MORE DAYS. I had two cartridges for each of my filters and I rotated them this way every 5 days. Some people go with a stronger solution of Clorox, but they use a dechlorination agent in the rinse. Remember nothing will kill your fish faster than chlorine in the water!!!

**Q: Will this fit the ML90770?**
A: Yes, it mentions it fits all Magnums, including the Magnum Polishing Filter so it will definitely fit it.
