Installing Your Filtration SystemAttach strainer (and extension tubes, if necessary) so that the strainer will be no closer than 2" to aquarium gravel once the system is hanging on aquarium frameHang system on aquarium frame and be sure aquarium water is at or above the minimum water level indicated on system's motor assemblyOnce system is properly in place, plug filtration system into outlet being sure to arrange the drip loop with the power cordSqueeze start button on Timestrip(R) and place it in compartment on filter hood so that the white area shows through the window. The bottom of the white timeline will darken approximately 30 seconds after activation. (Important: If bottom of timeline does not darken, then the Timestrip(R) has not been activated and you need to squeeze the button again.)Maintaining Your Filtration SystemChanging the Carbon Filter:When the Timestrip(R) in the filtration system's hood has turned completely red, it's time to change your filter. Note: It's important to change your carbon filter when the Timestrip(R) indicates it is time to do so because that means the carbon filter has reached its capacity for removing toxins.Open the system's carbon filter access door and lift carbon filter carrierHold carrier above doorway for a few seconds to drain water then invert carrier to a 45° angle and carry to waste binSqueeze carrier handle to drop dirty carbon filter into waste binInsert clean carbon filter into carrier (tan-colored floss should face front), drop carrier into system and close filter access doorSqueeze the start button on the fresh Timestrip(R) and replace old strip in compartment on filter hood so that the white area shows through the window. The bottom of the white timeline will darken approximately 30 seconds after activation. (Important: If bottom of timeline does not darken, then the Timestrip(R) has not been activated and you need to squeeze the button again.)Cleaning the Bio-Scrubber(TM):Do not dispose of the Bio-Scrubber(TM) unless it is damaged. It is a permanent part of the filtration system and not meant to be replaced or disturbed. If your Bio-Scrubber(TM) should ever become clogged as evidenced by restricted water flow or water to flowing over the top of the Bio-Scrubber(TM), follow the procedure below.Remove the system's hood and remove the Bio-Scrubber(TM)Gently rinse the Bio-Scrubber(TM) under cool water to dislodge clogs. Do not use soap or any other cleaner. (Note: Do not remove the beneficial bacteria growing on the Bio-Scrubber(TM). This bacteria turns toxins into harmless compounds.)Re-insert Bio-Scrubber(TM) and snap system hood back into place
