I dropped one of these in the tank and my filter was good for almost a month. The indicator barely moved. I removed the cartridge from the tank and intended on getting a new one from the store. I put it off and forgot and my filter was bad by the end of the week. My new filter only lasted 2 weeks without the cartridge. This cartridge extended my filter life by almost double. Probably would have been longer if I had replaced the cartridge sooner. $30.00 later & replacing my filter AGAIN I'm buying more of these. They definitely help. *and changing the cartridge once a month is extremely convienient compared to liquid chemical solutions you have to add each time u fill the tank* Source: http://www.amazon.com/Filter-ProTec-Cleaning-Cartridge-HWLPC2/dp/B0013MLOD6
