"This small filter is wonderful for low volume aquariums. Makes absolutley no noise if set up properly. Comes with regulator to control air flow (you will need to cut the tube that runs between the pump and the filter and insert the regulator there). If the bubbles make too much noise, simply lower the air flow. The pump itself will make noise if placed on or against something that will vibrate. If it makes noise, reposition the pump so that it is not touching anything it will vibrate against. I suggest that you still do a partial water change once a week, especially if you have a large number of fish in your small tank. Great filter, mine works wonders on my 4 gallon aquarium. If you need a filter for your small tank, I highly recomend this one.
This kit is perfect for the beginner fish-owner, or for someone who does not already have the tubing and pump. The best place to put this filter is on the back wall of the aquarium (you can always hide it by putting plants in front of it!), or on the bottom if you do not have any gravel. This filter does not work well as an undergravel unit, as the gravel makes the filter cartridge difficult to change."
