I've had a lot of questions about the filter system of the Mega Tank project and specially about the airlifts we are going to use. This is a really cheap way to move water around in your tank in massive amounts. The ones we have build are big but when you make them smaller you can use them in the smallest tanks their are. I have put detailed pictures online about building one. So hope you enjoy and learn something. They are in the Mega Tank chapter on my site.
