Penn-Plax Super Battery Powered Aquarium Gravel Cleaner

This makes a great stir stick, especially if you are hoping to make your tank water really dirty. Looking to spend your soon to be ex-spouse's money on something that doesn't work? Buy this! If you hoping to clean you tank though, don't buy this product. Run away as fast as you can. Instructions were probably written by someone that never actually used the product. Be sure to put the filter bag under the water, then after about an hour, it will kind of start working. Suction is very slow. So your water gets dirtier before it gets clean. This company seems to have made the product not transparent so that you can't see that it does not work properly. I would avoid any products made by this company, especially after watching review videos. I am disappointed in Chewy for selling bad products like this.

I use the cleaner to remove the dirt inevitably covering aquarium plants with time (fish poop, micronutrients precipitates, etc.). People complain that the Cleaner does not help because the suction is too weak, but is actually does! Stronger suction would damage the plants. You need to slightly agitate the water above the plant right below the input of the cleaner and the dirt will go in without damaging the plant. The process is slow, but it works well once you get adjusted to it. Four (not five) stars because the cleaner is a bit cumbersome to use, it could have been better designed to fit in the tank. You need to to learn to move it around "just right for you" to use it effectively.

I’m so glad I found this vacuum at Chewy. I had been looking for a while to replace the one I had that broke after many years. It works great! The only thing I’d comment on is I wish the tube was more clear. I like to see the debris going up the tube. It’s very satisfying!
