🐠 WMYCONGCONG 6-Piece Soft Biochemical Sponge Filter Set for Fish Tanks and Aquariums - Available in 2 Sizes Review

So happy I found them, I use them in all my tanks. Will be buying more soon as I never know when I'll be buying a new aquarium.

Very small and very loud when you plug in the filter, it's made. I had to cut out all of the middle plastic and put an air stone on the air hose to make it quieter. I wouldn't take more than 10 liters.

Additional bottom weight required. Mine kept floating so I had to secure it as best I could. I ended up buying suction cups and using them on the tube to keep it from floating. Otherwise quite nice and variety is a plus. Contains 3 short and 3 long.

I only wear them for about 5 hours and I can already see the difference! I'm not a big fan of traditional filters so this set was perfect for me. I used stock size for my 20 gallons and small for my 10 gallons. All I had to do was hook it up to the airline and it was ready to go. Be careful when you put them in the water, squeeze them well so they can soak in the water and sink to the bottom.

I need foam filters for my 10 and 20 gallon aquariums and I need them to be relatively small. A typical sponge filter is too big and looks like a nightmare to look at. Use these filters. the tank is too high or too long. Simply unbeatable for the price!

At $16 I was a little concerned that this item was too good to be true considering individual sponge filters cost $3-5 but before all with random inconsistent descriptions on this product page. But I received three smaller filters and three larger filters as shown in the photos, all parts are intact. They arrived in one package rather than individual boxes so I couldn't tell if they were "OEM" products. but they look and work as they should.
