PawflyAquarium Nano Bio Sponge Filter Quiet Betta Fry Shrimp and Small Fish Foam Filter with Tubing Suction Cup Check Valve Connector and Control Valve Accessories for Tiny Fish Tank up to 40 Litre

The media could not be loaded.  I bought this for my newly hatched fry, and it’s keeps the water clear. Cheap price also.The only issue is that I can’t seem to find the replacement sponges.You will need a pump for it.

It works, its just unfortunate it wasnt the size i ordered. Need to check the dimension before you install it.

Easy to assemble, does what it's supposed to do filter the water

It’s a great little filter. Love the air pressure valve on it. Hooked it up to my air pump and it worked. I did buy the bubble long bar, so used this instead but put the air valve from this on there to control the bubbles. It worked great.For a bigger tank I would use more of these or get a bigger one. but for a small tank this would be great does the job of adding air to the water and filtering the water.I have an electric filter and air pump, but will be keeping this little gem if that goes. For the price it’s a great emergency back up.

I modified mine to improve how it works.I cut out the central part of what they call the basket. Made a hole near the bottom of the lower basket. Put a small air stone on the air tube and pushed it up to the top basket. Much smaller bubbles coming out.To make it sink I cut about 2inches off the bottom of a small plastic drink bottle (kid's size), The filter just pushes inside it. I put some small gravel in the bottom then. Drilled a few holes in the drink bottle bottom.It now draws water through the sponge and the drink bottle. And good small bubbles from the top.Much better.

Great size, aeration and easy to setup with a control value. I’ll buy more in future

Bubbles are a little larger than expected, but it's fairly quiet and ideal for a small tank set up

Bought this for my angelfish fry tank and so pleased with it I'm going to buy one for the guppy fry too!

Llevo un mes usándolo y va perfecto en acuario de 10 litros.

L'ho preso per una boccia da 5 lt in cui tengo le palorbella in esubero ed in effetti l'acqua è molto limpida. Non ha materiale per batteri ma ho messo sul fondo un po' di cannolicchi ed un anforetta in ceramica che qualche battere lo fanno proliferare.

Lo uso per un microacquario dove un filtro non ci starebbe.

The media could not be loaded.  Dieser kleine Schwammfilter der mit einer Aquarium Luftpumpe betrieben wird ist optimal für meine kleinen Aquarien. Kann ich absolut weiterempehlen.
