Because of the weighted foot, you can place it anywhere in the tank and it will stay put.īy itself, this sponge filter can be kind of loud. This filter is free standing, so it doesn’t need to be attached to a tank wall. It keeps the sponge from moving around once the air is pumped through it.
This filter features a large, cylindrical sponge, a weighted foot that keeps the sponge off the floor of the tank and a clear lift tube. It’s a great size for 20-30 gallon tanks. The Hydro-Sponge III is the biggest of the five filters we looked at for this article. There are several different sizes, for teeny tiny nano tanks all the way up to 100 gallon tanks. Aquarium Technology Hydro-Sponge III: Best for 20-30 Gallons (76-113 liters) Now you know more about what sponge filters offer, you can use my reviews to make an informed decision on which one is best for you. Different air pumps may cause different decibel readings. P ro Tip: All of the filters were connected to an Aqueon QuietFlow 10 filter for testing. We took lots of notes and pictures along the way to document all our findings. We measured the noise level from each filter with a decibel meter to get an idea how loud they really were once they were installed and if there was any kind of workaround to make them quieter. We connected each one to air and let it run for a few days so we could test how loud it was and get an overall feel for what it’s like to use it day in/day out. We unboxed each filter and set them up in one of our 10 gallon (39 liter) tanks. We bought five different sponge filters so that we could use them and compare their features to decide what kind of tank each would be best for.
