🐠 Enhance Your Aquarium with BASE WAVE U-Type Tubes: 5pcs Aquarium Co2 System Air Pump Accessories with U-Shape Connector Review

These little knees fit perfectly around the edge of my framed fish tank, giving it a nicer look and preventing the duct from twisting and reducing airflow. I highly recommend it!

They are great for cleaning my plane. You will need some trimming if your tank has an edge. Standard airlines will also need some negotiation to get them.

Makes my CO2 line much neater. This is made for rimless tanks, but will only fit the rim of a 10 gallon tank. The spikes are a good size and the CO2 line is tight and doesn't let gas through. Just received them and will update if there are any long term corrosion issues.

It's damn cool and worth the price. They are heavier than expected, easy to install, just lubricate both sides first with some water from your reservoir and then slip straight into your air hose with no problem and they are amazing quality. Highly recommended and I would 100% buy more if I needed them that much

Very good technique. However, if your aquarium has a rim, this really isn't for you. You CAN use it in some cases, but you have to cut notches in the rim for it to work. If you have a rimless aquarium, I fully recommend it. If you have a rimmed aquarium I would suggest you go through it; It's not worth constantly making changes to your tank that you need to make.

Super for self-made aquarium covers. Will never crush, bend or lose airflow. I had two airlines so I decided to give it a try. Glad you did! Bought 2 more packs of 5 to change all the airlines in my tanks. It couldn't be easier. Cut the airline where you want, make a bend and plug and play! So far the first batch I bought in mid-September has worked well. Definitely a 5 star product if you're willing to shell out $3 each. Edit: 11/26/2018 I should also add that they fit very nicely on my rimmed
