Review on Enhance Your Aquarium with uxcell 4mm Striped Air Tube Airstones - Colorful 4pcs for Vibrant Underwater Experience by Brandi Walker

Updated review: I've actually used them more and found that bubbles come out after 2-3 days, which is really good! Also, since they are made of plastic, they are very easy to clean and reuse. Previous Review: I was looking forward to using these in our home and work tanks and I bought 2 sets but didn't produce the bubbles we were hoping for. Tried everything, but whatever. We have to admit that they looked cute and colorful in the aquarium, but again we use our air stones since we need a lot of bubbles.
