Changing the Filter Cartridge: 1. Open the system's Carbon Filter Access Door and lift out Carbon Filter Carrier. 2. Hold Carbon Filter Carrier above Carbon Filter Access Door for a few seconds to drain water. Then invert Carbon Filter Carrier at a 45-degree angle and carry to waste bin. 3. Squeeze Carbon Filter Carrier Handle to drop dirty Carbon Filter Cartridge into waste bin. 4. Insert clean Carbon Filter Cartridge into Carbon Filter Carrier (blue-colored floss should face the front). Drop Carbon Filter Carrier into system and close Carbon Filter Access Door.
Cleaning the Bio-Scrubber Insert: Note: Do not dispose of the Bio-Scrubber Insert 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 Insert should ever become clogged as evidenced by restricted water flow or water flowing over the top of the Bio-Scrubber Insert, follow the procedure below.
Remove the system's Hood and remove the Bio-Scrubber Insert.
Gently rinse the Bio-Scrubber Insert 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 Insert. These bacteria turn toxins into harmless comlbs.
Re-insert Bio-Scrubber Insert and snap system Hood back into place.
Attach strainer (and extension tubes, if necessary) so that strainer will be no closer than 2 inches to aquarium gravel once the system is hanging on aquarium frame.
Hang system on aquarium frame. Be sure aquarium water is at or above the minimum water level indicated on system's motor assembly.
Once system is properly in place, plug filtration system into outlet being sure to arrange a drip loop with the power cord.
Squeeze start button on Time strip® 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 Time strip® has not been activated and you need to squeeze the button against)
not the greatest filter out there. I used to use two ten gallon tank filters for my turtle tank and thought it was time to upgrade since now I have a 50 gallon tank. I did tons of research before I chose to buy this filter and thought it was the best one for me. turns out its just as loud as having two filters and doesnt help with the cleaness of the tank at all. The piece that is suppost to stick down further into the tank just kept falling off so now it only filters the top of the tank. I have to find a way to tape it on I guess. And the things that hold the actual rechangable filters in place broke the second I opened them, the are suppost to snap in place but the cheap snaps broke the secondnot the greatest filter out there.

I would not recommend buying this filter... When it's working it works OK, but I have bought 2 so far-1st one stopped working when power went out from a very severe thunderstorm and now the one I purchased just a few months ago went out because my son shut the main circuit breaker off to the house when I wasn't looking... Now I have a 55 gallon tank with no filter because this product is junk... I am not happy!!!!!

I haven't used this filter yet, still setting up new aquarium. However, while I was tying to assemble it, it kept falling apart. I'm not new to all this, and I feel this product should have been better made. I hope it runs properly and doesn't fall apart and spray water everywhere.
Never will buy again

Easy to Change Cartridges

I did not have high hopes for this product but just needed a little filter for a tank that I use for propagating aquatic plants. It exceeded my expectations. It is not any quieter than other filters, but not louder either. There are numerous features that make this filter a pleasure to maintain. I will be replacing my other HOB filters from their sister company MarineLand with these.

It works nice but it makes a load vibrating noise no matter how I try and hang it off the tank.
