- When cleaning the filter, unplug it. Do not use detergents or soap, as residues may harm fish.
- Do not use sand in the aquarium when using the internal filter.
- If the foam grid becomes clogged, remove and wash with water until debris is removed.
- Replace filter cartridge every four weeks. To change the cartridge, unplug filter, remove and replace cartridge, and re-plug the filter.
- If the motor is noisy, unplug the filter and remove it from aquarium. Remove the motor, open its cover, and flush gravel, leaves, or other debris with cool water. Replace the motor into the filter, mount the filter in the aquarium, and re-plug the unit.
- It takes a few weeks for new aquarium water to be conditioned. You can use EasyBalanceTM to speed up conditioning. During the conditioning period, feed fish lightly and be sure all food is consumed.
- When putting tap water into the aquarium, add AquaSafeTM water conditioner to neutralize harmful chlorine and chloramines.
- Insert the filter cartridge and foam grid. (Note: the front of the foam grid is market "front" and should face the front of the internal filter.)
- Hang the filter inside the aquarium and press the suction cup against the aquarium glass. Drape wire over the aquarium wall.
- The lip of the internal filter should be above water level, and the bottom of the internal filter should be at least one inch above the aquarium gravel. When positioning plants and other items, leave approximately 1/2 inches of clearance around the filter.
- Raise or lower the internal filter by adjusting the filter hanger. Rotate the filter hanger 90 degrees, remove it, and replace it in an alternate alignment hole. (In turtle tanks, the bottom of the internal filter should be submerged in at least 2 inches of water.)
- If the filter hanger does not fit on the aquarium frame, it can be replaced with an extra suction cup (provided). When pressed firmly, the suction cup will fit snugly into the filter.

So I bought this filter for my razorback musk turtles. They are pretty tiny guys, but God do they make a big mess lol. After trying several different aquatic filters this one by far performs the best. The water appears crystal clear and I love that! No more yucky films at the top and no odd colors in the water. And best of all I've had the same cartridge in there for weeks and the water still appears clear! Get this you won't regret it turtle lovers.

I feel like product has a few design flaws, for starters a cover would be nice, slower intake would be amazing! The intake on this filter in a 5 gal tank is so much the water flows over the filter cartridge, I feel like it’s not doing what it’s ment to do as well as it could! I do like that the bar is adjustable and I can raise or lower the filter in the water, but over all not impressed. It’s a so so filter

I bought several to use where space is too tight. These require more frequent filter changes with turtles than a canister but changes are easy quick and cheap. Could use additional fasteners both suction and hanging clips as turtles want to move these things. Easily modified. I might buy a few more for future use. Chewy is great. I spend alot on my Trachemys scripta elegans.

I have a 29G tank with 6 platys 1 betta fish 4 ghost shrimp I wanted to up my filtration and whisper fiters are usually my fav this one had such a hard current that the betta fish struggled to swim agianst it across the other side of the tank... I instantly knew it wasn't going to work out, or course you can use like waterbottles or soda cans to cushion the flow but if you have to put something that makes the tank look funny or weird it's not worth it otherwise I'm sure it's a good filter that works just too strong of a flow :/

The filter it's self is fantastic. Kinda big but really good. And whisper fits it. It's very silent. HOWEVER a few things I wanna point out. Well the suction cup that came with the filter was too small so I used a decorative item to hold it up and stold the suction cup from the thermometer I bought. And now it works just dandy. But human error and a lack of care for customers kinda makes me a very displeased customer. I'm lowering my star ratings because the lack of parts for the filter it's self. It's very easy to correct a wrong sized suction cup people.

Can't hear a thing, this is really one of those filters for when they say its quiet THEY REALLY MEAN IT there is also no splash either.

This filter is decent, the only problems I've had with it is that slime and algae tend to accumulate on it and make it kinda gross on the outside, it's easy to wipe off just yucky. It's a very quiet filter though and would work best with fish that don't produce a lot of waste.
