Review on 🌿 FZONE Aquatic Mini Glass Lily Pipe Skimmer: A Must-Have for Mini Nano Tank Filter Systems by Stacy Malcolm

I put them in a 6 gallon nano tank and they are the perfect size. The overflow part works great, you just need to set it up properly. I really like that they have a suction cup part that attaches to the pipe from the outside, rather than relying on a clamp on the suction cup like others. It feels a lot safer. The quality is generally good and it was a good price.
