Tetra Extension Tube for Whisper 30 and 40 Filters

I purchased this extension hoping to extend the filter tube however when I tried to put it on my existing filter Whisper 20 system, the tube was larger than the existing one and would not fit

Each section fit into the existing 30 Top Fin I have without problems. I also have a 20 Top Fin. Top Fin is sold by Pet Smart and appears very similar to Whisper pumps. A point to remember is this tube does not fit the 20 model. The 20 has a smaller tube. Apparently, the 20 does not have an available extension and comes with a tube length too close to the discharge in my opinion. Both pumps work better, also in my opinion, with the tube inlet closer to the tank bottom. I bought aquarium silicon sealer and glued this tube between the 20 tube and intake section, let dry 24 hours, and have cleaner clearer 20 and 30 gallon aquariums.

Looked around for an extension, since I bought a deep 60 gallon hexagonal tank, you need a longer extension for the intake to get down into the tank for better filtration. I wish power filter companies would automatically include a long extension, especially since it wouldnt cost that much to include it anyway, but thank goodness you can get it here, on Amazon.

In the description it says that the tube will also fit 10-20 Whisper models. All LIES because it didn't fit at all! I was so happy because I looked everywhere and couldn't find this extension tube. When I saw it online I decided to spend the extra money to have it. Now I have a worthless $8.00 piece of plastic. Save your money if you don't have a 30 model!
