Here is the video I promised, forgot to show the air pump, I'll do that next.
Great setup. I said great setup......hello.....can you hear me?.
Mine have both been up over a year without cleaning. When the water level is lower on the air lift side, time to give them a squeeze. That's all the cleaning they need.Interesting set up. It's an example on how you can build a simple filter without the complication of plumbing a sump system, or cleaning a canister filter. I am wondering how you hold the foam in place, how often do you clean the foam and what will happen when the clogged up foam is compressed.
If you don't like the air bubbling noise, you can easily replace the air lift with a power head. But air lift provides not only water movement, but aeration that is highly beneficial.
Nice job on the corner HMF setup!!
What is the reason you added the 90 degree fitting to the outlet of the air lift? I find that if the outlet end is mostly submerged but still has a space at the top above the water line, it is very quiet.
