Aquaponics, simplified, just one pond pump running right now. Probably moving so trying to get rid of as much stuff as possible. Fun times!
I’ll probably switch out the pump for one that is using the irrigation rubber tube and irrigation barbs, makes everything flexible and easy to clean. 
I love this setup. I’d really like to try and build something like this. I have a couple 60gal rectangular plastic basins. I just need pump, timer, and some tubing.
I’ve never done anything like this. Could you point to any how-tos for putting this all together?
Start with a simple concrete mixing tray from Home Depot, you will need to drill a hole for 1/2” threaded bulkhead, then 3/4” threaded bulkhead. The 3/4” is your drain. 1/2 goes to pump.
Get rubber irrigation tubing from Home Depot and get 2 straight 1/2” irrigation barbs. The barb will screw into the pond pump then to the tubing then to 1/2” bulkhead.
The 3/4” hole will set the level of the tray, you can use a 3/4” male to slip pvc piece. Cover both holes with net cups, 3” or larger.
I use a mechanical timer, 15 minutes on, 15 off during summer, can be less depending on your location.
Here is a similar build I’ve done, let me know if you have any additional questions. https://youtu.be/CuO5ZrKzZj4?feature=shared
