That filter simply isn't built for continuous operation. BTW
, it is quite expensive 8O , so take care of it. It operates with diatomacious powder. The powder adheres to the micron filter and you need to be sure all of it is attached (that's why the glass jar), before you place the tubes in your tank. Otherwise you'll have a tank full of the powder.
It filters out particulate matter down to 1 micron and makes your water crystal clear. Because of this, that micron filter becomes clogged easily and you can burn out the motor. To give you some idea, I'll run mine for about 1 hour a week on my 125 gallon tanks. It's a very useful tool for the serious aquarist. OH....make sure you've oiled the motor before using (especially if it's been sitting for a while), and keep the rubber O ring well lubricated. Good Luck
