When I returned home from offshore here is what I found.

This is the most expensive part. My mommy bought it for my cause she loves me. It was 22 bucks at home depot. It pretty much makes the system. It is an outdoor digital timer it has 28 different settable time events. I have it set to come on in the morning and turn off every 2 hours for 30 minutes and turn off at night. It runs the 250 gph pump in the fish barrrel.
When the water drains back into the fish barrel it goes through a venturi that causes a lower pressure by speeding up the water flow. It sucks air in a little hole and aerates the fish water. basically it's just 2 reducer fittings from 1 inch to 1/2 inch and a piece of 1/2 inch PVC with a hole inn it. It's super high tech. I keep the barrel covered to keep the temprature down for the fish. I just use a bungie and an old towel.
Once the water drains into the growbeds it goes through the paint cap & lemonade container filters and back into the Fish barrel. The process starts all over again. Here there are paint caps setting inside the lomonade\rock filter. The paint caps are cutout in the center and have holes drilled in it to let water through. A toothpick is in place to keep the PVC pipe from pushing the screen and Bird gravel out. I used bird gravel because it has oyster shells and activated carbon in it.
This is an ebb and flow system where a reservoir fills and then floods the grow beds to give more air to the roots. Here the aquaponic system fills the tub from a pump in the bottom of the fish barrel the water rises up until it starts flowing through the PVC into the 2 litre bottle. once it fills enough the weight of the water over powers the weight holding it up which is connected to the fishing line inside the reservoir, the bottle falls and opens the flush flapper valve in the bottom of the tub. The water flushes out through the PVC drain pipes that have holes drilled in them. There are some vases in the tub to control the amount of water flooding into the grow beds.

My son and I went over to our local neighborhood pond with a small fishing pole and a can of red worms. we caught 9 fish for the aquaponic garden. the fish were sun perch and bluegill. We used number 10 mustad hooks and a bobber. Today I noticed that there were only 2 of the minnow type fish we had netted in the pond. The day before there were about 30 of the little fish. I guess perch eat minnows.
So, I decided to add a dirt garden to my backyard due to the fact I had so many extra plants growing. I used the tops of the walmart containers that I used for the plant beds in the aquaponics garden. I had been throwing my dog poop in these 5 gallon buckets for the last 3 years and decided to dump a bottom of dog dooky layer in two of the dirt gardens. I put top soil over the top. the plants seem to be doing well. I'm afraid they might do better than the aquaponic garden. by the way the dog poo was completely broken down and does not even smell like poo anymore.
