AQUAMIGOS Tip
Choosing the right size air pump is just as important as choosing the right filter. A pump that is too small may not provide enough oxygen, while one that is too powerful can create excessive water movement. The AQ Series gives you the flexibility to choose the ideal model for your aquarium, from compact nano tanks to larger community setups.
