Review on Pawfly Standard Aquarium Accessories Connectors by Danielle Rogers

I wanted to add a few more aerators for my fish to oxygenate the water. I like this product the most because it allows you to get creative and create different pipe paths to have multiple airstones. With my 40 gallon pump I have 2 rocks and the air tube is submerged under rocks and gravel. I like the one way valve (I'm assuming it works since I haven't had backflow) and how you can regulate the airflow. My tetras don't like a lot of bubble flow, but I have a 40 gallon (powerful) air pump. This allows me to adjust it to make them more comfortable! There are many fittings/valves and the pipe is long; it will accompany me for a long time. This works if you have a very powerful air pump and need a lot of air stones, or if you have a weaker pump and just want to replace the stones/tubes when they get too dirty.
