aquaponics is real, however I pretty much think it is more or less reserved to places what have temperatures above 5 degrees year round more or less if outdoors or a home that is contantly heated to atleast 5 degrees celcius..? 50 f??? depending on species, as the heater costs can eat up a lot of electricity. You need to run an aerator 24/7, which is another energy cost, if it fails your fish will all die in minutes, you need a backup on an emergency switch system to kick in on a 12v battery to insure that power failure will not kill all your fish. I think there are some algae options like spirulina (of doomsday preppers fame) There is a cheapo option to use a bathtub overall I think it would run $100-$200 and some species take a year or two to bring in. There are startup costs, although I am curious about railing frogs... to see if that can be done cause getting tadpoles is easy and frogs are very edible.
It is real, I have a video on it if you are interested it is a huge video though like over a gig.
Basically the costs are
bilge pump ($20-40)
backup bilge ($20-40) needs to be able to pump up water ... with 12v etc.. leaders
12v battery as a backup
a siphon gauge system to drain your water when water levels get high (no clue)
some seedweed concentrate extract to get the cycle started (no clue)
urea (or piss about 1 table spoon) (mostly free)
a waterproof bin you can plant your stuff in, must be able to support a load of gravel or clay beads)
seedlings you want to grow
extra bathtub or bin to hold your water the bigger it is the more fish you can hold but the size has a ratio to planters so a really big area like a swimming pool will require an entire farm to purify... and have a whole lot of fish.
a few seals , and a few tubes to connect your sump and siphon drain too...
to overly simplify that is it. some fish need apply, expect some to die.
I think you could probably turn a bublepump coffee mater / preculator into an aerator.. if doing it on a DIY hack basis.
I'm thinking a coffee maker or multiple coffee makers could make this aquaponics thing much easier..
you must understand how bubblepumps work to really understand why...
Here is an example...
here is an explanation
the coffee maker is a "simplified aquaponics system" of smaller size.
some tuning may need apply, but I do suspect you can make superior aquaponics system out of coffee makers, perhaps a simple aerator,... and a siphon valve.
Here is an aerator bypass
it is called a venturi
In seeing this though I think you could create a mixed air water siphon which with this venturi could aerate based on siphon suction and downward water pressure of a siphon gauge release... which means all you would need is this venturi sucking in air at the drain point... and you would however need to run your bilge ongoing.. the aerator may be needed as a backup but you could probably cycle your aerator to only run when your siphon gauge wasn't operating..
hopefully you can undertand how this could save energy in having a downward suction of air with a venturi.. which operated on cycle with siphon release, the switch gets turned off and the aerator on when the bilge and aerator get turned on to pump water up to the plant bed.
to explain in a picture.. sorry bad drawing...
the point is with a coffee maker or two or a coffee maker and aerator you can get an aquaponics system going. but if you want your fish to live you need a backup aerator.
you would need to wire a switch between the siphon valve drain and the bilge aerator circuit. this way perhaps the aerator only needs to run if the pumps/pumps fail.
here is another interesting zenturi video
