It's easy to use and works really well - This is a fantastic filter. We had an issue with our vacuum and things got icky in the tank for a bit. There was a visible difference overnight with this filter. I appreciate how easy it is to use - I tried a couple of other types. One required replacement filter cartridges regularly. Another had sponges that lifted off two spikes, which seemed like it would be easier, but the whole unit kept detaching when I tried to remove the sponges and I kept having to reset the whole thing, or parts would sink to the bottom of the tank. This one lets you leave the top part of the filter attached to the suction cups - you just twist the bottom section away from it to take it out of the tank and clean the sponges. Of course you also need an air pump to go with this. The lid to the compartment where the sponges are is tricky to remove, but I'm able to do it without a tool - I just approach it from the circle in the center and lift a little in every direction before it pops off (as opposed to prying it from the edges). The bubble spray is pretty powerful, and at first my fish avoided that area, but they got used to it quickly. It's very easy to see when it's time to clean the sponges (especially the yellow one), so it's a good visual reminder. I can't describe how happy I am to have an effective, easy filter. It's also priced really well compared to some of the other more complicated models. Glad to recommend it. Review: Small and Efficient - I love this filter. It’s very quiet, and it’s incredibly easy to assemble and clean. Despite its small size, it works surprisingly efficiently. I highly recommend it. ## Features - PERFORMANCE – Max. Flow 130GPH (500L/H), Max lift 2.5ft (0.76m), Power 3.5W. This fish filter is ideal for fish tank size of 10-40 gallons(Choose the right filter for your tank). A filter can’t cover tanks of big differences in capacity (as claimed by some products online)! Follow our recommendations for your tank. - SAFETY – The aquarium filter is fully submersible with epoxy sealed motor. Each fish tank filter has been submerged in water and tested with super high voltage to ensure the safety. - 3-STAGE FILTRATION – 3 sponge blocks – coarse sponge, carbonized sponge and fine sponge provide 3-stage filtration. COARSE SPONGE filters out large size impurities such as food residue, fish excrements, plant leaves etc.; CARBONIZED SPONGE removes odor, chlorine and fine particles; FINE SPONGE polishes water before it goes back to tank. PLUS the transparent box makes it easy to check the filtering material when they get dirty. Search code “B09W23YJD7” for the replacement sponges. - AERATING WATER - Oxygenation is very important to your fish. Different from most of the filters in the market, this turtle tank filter also provides an air venturi and air tubing to increase oxygen supply in your fish tank. REMINDER: The air inlet must always be kept above the water level. Otherwise, water backflow may occur. - KIND REMINDER – If your tank is very large, choose 2 filters! Place a filter at both the left and right corners at the back side. You will get full filtration and great water circulation in your tank! PLUS this filter is with dual water outlet to ensure even water distribution in your fish tank! ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.2 out of 5 stars 1,575 Reviews | ## Images ![Aquarium Filter 3-Stage in-Tank Filter Internal Fish Tank Filter Turtle Filter for 10-40 Gallon Fish Tanks with Dual Water Outlet & Aeration - Image 1](https://m.media-amazon.com/images/I/71TRynvUKaL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Why is the filter not aerating?** A: 1. Make sure to block the side water outlet in order to enable the aeration function. 2. If filter is placed too deep, it may not aerate. Simply raise the filter to resolve this issue. 3. Filter sponge may be clogged. Clean it to restore aeration. **Q: Should the filter be exposed to the water surface during operation?** A: No, when the filter is working, it must be fully submerged in the water. **Q: What is the order of placement for the 3 types of filter sponges when replacing them?** A: The coarse sponge (blue sponge) should be placed at the bottom of the filter box, followed by the activated carbon sponge (black sponge) in the middle, and the fine sponge (yellow sponge) at the top. **Q: How can I open the filter box top cover?** A: Remove the pump head first, then insert your finger into the hole in the center of the top cover, and then pry it open. **Q: Why should the air inlet of the air tube be placed above the water level?** A: The air inlet must always be kept above the water level. Otherwise, water backflow may occur. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Recommend! It's easy to use and works really well *by J***F on January 30, 2026* This is a fantastic filter.
