Hey guys. I just finished my new Backporch Apartment Aquaponic System using 2 vertical zipgrow towers that drain into a DWC trough. I also added a small tub that I filled with hydroton and cinder to work as a solids filter and to pre cycle media for when we help people start their own systems. Here's a video:
It's not really being used for anything but to filter some solids, pre cycle media for people and start seeds in. I added the bell siphon to use just in case. It doesn't really fire very often.
But good advice about the algae.
When I take out this media I will work on the bell siphon and get it just right.
