Review on Pawfly 20 Piece Aquarium Suction Airline by Dana Franklin

Bought a *brand* new acrylic tank, meticulously routed the air lines and put on some air stones immaculate which was one of the cleanest setups I've ever done. Did a test run before adding water and left a few cups in while going to bed. I've experimented with different cup configurations so I had some higher and some lower just seeing what looked and worked best. Left her there and that was a mistake. Something terrible happened during the night. I removed the cups the next morning to continue the project. I saw something like water rings there, like condensed glass bowl leaves on a wooden table, but it couldn't be erased. If you run your finger over it you will feel that it is covered with frost. Corroded by a strange chemical reaction that ate into the walls of the aquarium and forever ate into every place the cups touched. VERY DISAPPOINTED Although I have to give credit if needed. The cups stick well and firmly. That evening one of them fell off but stayed long enough to stain the walls. They were soft and pliable, but apparently the oily coating on the cups breaks down the acrylic and makes them translucent in all places the cups come in contact with. Visually ruined a brand new tank. And that's legal crap. Didn't expect that. plastic tank? AVOID THESE CUPS! Cup? You must be doing a great job.
