If you have a shorter tank (like a 10 gallon or a 20 long), please see the sizing chart below. Shallower tanks may require trimming of the Easy Flow uplift tube. Additional Supplies Needed The sponge filter does not produce air on its own, so you also need to buy the following components to run the sponge filter: — Air pump — Airline tubing — Check valve (to prevent water from pouring out of the tank when the power is off) Pore Size: 25ppi (different manufacturers rate porosity slightly different as it's an approximation) Cleaning Instructions: 1. Use a fish bag, ziplock bag, or pitcher to put around the sponge while inside of the aquarium. 2. Lift the water and sponge out to catch the majority of debris that will come off while removing. 3. Remove the foam from the plastic basket. Use the aquarium water and squeeze out the debris from the sponge. 4. Discard the water and get more water from the aquarium. 5. Repeat Steps 3 and 4 until sponge filter is mostly free of debris. 6. Scrub the air collar as well to clear out any debris or algae that has covered the holes. 7. Reassemble the sponge filter, and install it back in the aquarium

> Frequently Asked Questions

Q: What type of sponge filter is the Black Easy Flow?
A: The Black Easy Flow is a coarse sponge filter with a 25ppi pore size and an air collar that creates smaller bubbles for improved performance. It includes an Easy Flow curved tube accessory that increases water circulation, and it operates using just an air pump and airline tubing—no cartridges or moving parts required.
Q: What supplies do I need to run this sponge filter?
A: You'll need an air pump, airline tubing, and a check valve to run this sponge filter. The check valve prevents water from flowing back out of the tank when the power is off. The sponge filter produces no air on its own, so these external components are essential for proper operation.
Q: Is this sponge filter suitable for betta fish?
A: Yes, the Black Easy Flow is gentle enough for betta fish, baby fry, shrimp, and other slow-moving species. The smaller bubbles and reduced noise level make it ideal for these sensitive aquatic pets. It's trusted by fish farms and wholesalers for its reliable, gentle performance.
Q: How do you clean a sponge filter?
A: Rinse the sponge in aquarium water to clean debris without using tap water, which can kill beneficial bacteria. Gently squeeze out debris repeatedly using fresh tank water. Also scrub the air collar to remove algae. The entire filter is completely reusable and lasts for several years with proper maintenance.
Q: What is the pore size and porosity rating of this filter?
A: The Black Easy Flow has a pore size of 25ppi with coarse porosity, and it features an anti-clogging sponge design. This coarse rating resists debris buildup while still providing effective filtration. Different manufacturers rate porosity slightly differently as it's an approximation, but 25ppi represents the pore density of this filter.
Q: What are the available sizes and prices?
A: The Black Easy Flow Coarse model is budget-friendly at $9.99 and currently in stock. Variants are available in Nano ($9.99), Small ($11.99), Medium ($12.99), and Large ($14.99) sizes. All variants feature the same coarse porosity and Easy Flow technology, allowing you to select the right size for your aquarium dimensions.
Q: How should the Easy Flow tube be positioned in the tank?
A: Adjust the height of the Easy Flow curved tube so the opening is 1/3 out of the water and 2/3 in the water. For shorter tanks like 10-gallon or 20-long aquariums, you may need to trim the uplift tube to fit properly. Consult the sizing chart for specific guidance.
Q: What makes sponge filters better than cartridge filters?
A: Sponge filters offer reliability with no moving parts and no replacement cartridges needed. They're completely reusable and typically last several years. This makes them cost-effective and low-maintenance. They're gentle on delicate fish, making them an excellent choice for set-and-forget filtration trusted by fish farms and wholesalers.
Q: Does the filter produce bubbles and noise?
A: The Black Easy Flow includes an air collar that creates smaller bubbles for improved performance, resulting in less noise compared to other filters. The design reduces bubble size while increasing water circulation, making it quieter and more efficient—ideal for fish sensitive to disturbance like bettas and fry.
Q: Why is this filter trusted by professional fish breeders?
A: The Black Easy Flow is trusted by fish farms and wholesalers because it offers hassle-free, reliable operation with no moving parts to break. Its gentle bubble flow is perfect for sensitive species like fry and shrimp. The filter is completely reusable and lasts several years, making it dependable for professional breeding operations.
