You don't have to remove a bulky light shield to harvest your algae, either. Just flip open the hinged door on top to access the algae screen when it comes time for maintenance. Open the door on top and loosen the quick-release union on the side. Lift the pipe and algae screen out and run them under water in the sink.You can use a soft bristle toothbrush to remove stubborn buildup. Be careful not to remove all of the algae from the screen as this will slow growth when you put it back into your system. Leave some algae behind to seed the next batch so that it will grow faster. Under normal circumstances, you will be harvesting algae every 1-3 weeks. WHEN TO RUN YOUR SCRUBBER. Many hobbyists prefer to run their algae scrubbers on a reverse daylight schedule to help stabilize the pH of your aquarium water. You can accomplish this by plugging the LED lights into a timer or aquarium controller and programming it for a 12-hour daily photoperiod that runs opposite of the daylight schedule of your display tank lighting. Algae Scrubbers are equipped with an emergency drain fitting in case the main drain ever gets clogged with algae. This item is in the category "Pet Supplies\Fish & Aquariums\Filters".
