I just finished with the videos in the aquaponics online course. The videos are coupled with presentation slides. It is the best online course I have had the pleasure of taking. If you are like me, online courses sound like a lot of reading and busy work. Well not this one. It feels like being right in the thick of things with Sylvia and Alan. As you might have imagined, most of the videos are shot in a greenhouse so you it really feels like a hands on course.
Now I am ready to fix my mistakes in my systems. Here is what I am going to start with. I need to replace my current media with something 1/2 to 3/4 inch size. My system gets clogged up because the gravel I use is too small and apparently has some limestone in it. I tested it and found that it bubbles up in vinegar. I prefer to use Fired Clay, but first I want to test a few samples of lava rock that I can get locally. It should be inert, but I will still test it and make sure I can get my hands on something that is the right size.
To your successful aquaponic gardening,
Scott
