I don't know if anyone is interested in growing their own food and vegetables but this Aquaponic system i have built works just perfect. i am i newbie when it comes to programming and i am sure someone could do better but all i can say is it works and works very darn well. i studied Arduino platform for a few weeks and the two programs are the start up which runs for 10 days and the run program cycles 8.5 times in 24 hours.

it uses AC as back up only utilizing the light out function on a charge controller at 24 volts and two solar panels supplying all the power to the system. it has an air pump that is on 24/7 with a water pump on for 8 times in 24 hours and two 24 volt solenoid valves on for 15 minutes every 2 hours. the whole system only takes 60 watts for the air pump @ 24/7, the water pump @ 80 watts for 5 minutes every 2 plus hours and each solenoid valve are on at separate times for 15 minutes every 2 plus hours @ 12.5 watts each.

i have built two systems near my house for people and they are very happy i designed the system and helped them build it. i made a few bucks off of it but not much. and yes i know aerate is spelled wrong.

the system in the video was before i installed it into it's permanent home. the LED lights indicate that stage complete which is LED 1 -5 with the red blinking LED shown upcoming stage. turning the sound up you will hear the relays clicking on and off working flawlessly.

The start up program is designed for the colonization of good bacteria. instead of taking up to three months to form good bacterial i  have taken it down to 10 to 11 days and here is how.

cycle the water for for three days to rid the water of chlorine adding vitamine C, add a bottle of food grade ammonia then circulate for one day. add bottle of Nitrifying  bacteria and circulate for 6 to 7 days then test for colonization . bugs took both times i built the system so then you can add the fish and plants making sure no soil is introduced to the system. wash off all soil from the roots before transplanting to the Aquaponic system as soil has bad bacterial and diseases in it and can harm the eco system.

when our world goes shit very soon people need to learn how to grow their own food to survive and this system is a good way to do it.

this method of nitrifying the system was studied and conducted by me and verified to work 100 %.

The system is what you call an ebb and flow system. the pump pumps the water into the overhead tank then shuts off. then the flood valve opens and floods the troughs from gravity. the system soaks for two hours allowing the nutrient to be absorbed by the plants then the drain valve opens and drains the clean water into the fish tank then the overflow tank. the water then sits for 15 minutes to aerate which is reoxygenating the water for the next cycle.

the above pic in the previous post is the cycle of Aquaponics system. the pic below is the actual system i built.

Each system can be increased or decreased in size according to your own desires as the gravity feed tank can hold up to 275 gallons. once the growing troughs are filled with growing media it will hold around 5 to 7 gallons of water so many growing troughs can be added in the range of 39 to 55 media beds depending on the size of the grow media.

the electronics involved are the pic below which were designed by me and me alone. i am sure you could alter the system to your liking.

As you can see from circuit diagrams the AC transformer is shut out of the system and not used until the LVT (Low Voltage Threshold ) is crossed which when designed properly will not ever be used if enough battery amp hour rating is in the range of 150 to 200 Ah.

if the AC should kick in the surge to the system will be minimal because of the four large 24v DC caps and the use of an inductor. also the use of circuitry to kick on at the zero crossing will help minimize surge currant which is incorporated into the AC relay.

the system uses the 24 volt light out function of the charge controller that activates two low voltage relays from NC to NO keeping the two systems completely separate. also the two buck power supplies keep the Arduino and the relays completely separate through Optoisolation also in case of an accident or short of any of the systems minimizing the chance of whole system failure.

this system can be completely Autonomous  when the Figuera system is complete or the 1932 Coutier device is used with these systems.

if anyone has any questions please feel free to ask or post your Aquaponic systems designs as this is about the very survival of the human race not corporate takeover of your lives.

There is multiple ways to run the piping from the gravity feed tank to the troughs. you can either run piping to all the troughs to feed individually but you will also have to have separate overflow and drains for each trough. you can also do as i did by cutting the drums and adding spacers connecting each trough together  so when the first drum fills it overflows into the next drum and so on until the last drum is filled and overflows past the valve into the fish tank to the overflow sump tote. this decreases the amount of piping needed and all drum drains are connected to one trough drain valve for less complexity.

here is a pic of the spacers used to connect the half drum growing troughs together. the two inch by three inch grove is plenty to keep the troughs from overflowing draining into the next then out the overflow drain.

Hey MM   ...  I wanted to have an aquaponics system. I noticed when you mentioned yours in some other comment. If I could afford it, I would buy a house with a swimming pool to do it in. Or a cheap system could use an above ground plastic pool.

What kind of fish do you have?

Both systems have Tilapia because they are very hardy in Texas hot weather. they are aggressive, fast growers, taste good and can handle not so good water conditions.

if you live in colder weather i would suggest Trout as they can handle extreme cold conditions, grow fast and taste excellent.

always be aware the the plastics in above ground pools may not always be good for the fish and may not always last that long. building a tank lined with special blue paint specifically designed for fish tanks or food grade totes are always optimal choice. also always use approved piping for water transfer as the regular will kill fish being toxic.

in the picture of the system the tank is 8 feet but two feet has a very small net across the tank for fingerlings so when you harvest the tilapia the larger fingerlings can be put into the main tank area. tilapia as i said are aggressive and will eat the fingerlings if to small thus wiping out the fingerlings in a matter of minutes.

the use of a whole pool as the fish tank would be for a very, very large system and not recommended for anything less.

This is one of my many hobbies in which i know quite a lot about through years of studying and back yard testing. i also build and service computers, build firewalls, routers, networking homes/small businesses and such for people i happen to meet through casual conversations at grocery stores and such. i also dabble in board design using DipTrace. i  do industrial sewing making car, motor cycle and BBQ covers as i was a parachute rigger in the military. i am a wiz at home audio and video using surround sound setups. making multi-screen video game set ups is also fun. my best setup was a three projector video game system using a 30 x 10 foot wall as the screen. the dude cried when i turned it on and played CALL OF DUTY MW3 with a wireless controller. i am also great with all hand tools with wood and metal lath work. i can fix just about anything especially if it has moving parts. i work a little on cars to,  like breaks, rotor replacement and the like. good carpenter also.

It is actually quite easy to grow anything in an Aquaponic system, having the perfect system with fish and plants using good bacteria to break down the Ammonia to nitrogen the  plants thrive on.

below is a picture of two chocolate mint plants. one was grown in a pot with water from the hose and the other was watered from an Aquaponic system.

it is hard to believe both plants are six to eight weeks old.

The newest Arduino IDE is 1.8.5 can be downloaded from here https://www.arduino.cc/

It can be used to program your Arduino board in which the two basic programs can be used on just about any Arduino board.

the Arduino platform is a great way to cycle your Aquaponics system as it being very low power and the optical isolated relays provide protection and a load up to 10 amp.

The system i have provided can also be used with just an AC step down transformer to 24 volts which the transformer is not very expensive.   24 volts @ 10 amp is plenty of headroom for this system and can leave room for a cooling system like the one below.

having 24 volt exhaust fans in the upper area  with louvers with an evaporative water trickle system in the lower half of your green house will keep things cool during the hottest days in summer and is very energy efficient to boot. the system can be incorporated with ease and minimal electronics which are everywhere on the net.

the pic below is the evap system that is easily incorporated near the ground level using a cheap 24 volt pump to pump the water from the catch basin to the upper trickle trough.
