Query: Makes fish tank maintenance so much easier.

My fish tank is 24 inches deep and I didn't like using the shorter tools, not to mention getting my hands/arms all wet.The interchangeable tools make for less clutter in my aquarium cabinet.Finally, no wet mess from sticking my hand in the aquarium to do routine maintenance. Even though my fish tank is only 24 inches deep, this product works perfectly for it. I'm very satisfied with my purchase!
