FISH inside ur tanks

I'd be interested in this but I think there are to many factors that could go wrong. What if your fish starting eating the roots? haha... but i'm not sure this would work. I think using nutes from bottles would be cheaper and better than fish crap? Could be wrong though.

Interesting idea but it wouldnt benefit you that much or not at all.Wether its the fish agitateing the roots or dieing from the chemicals in the tank.I could imagene that fish shit would provide some type of nutes wether or not the roots will be able to uptake ill leave that to the experts, but go spend the money from the fish on a bottle of booster..It would be a cool thing to look at a bunch of nice fish in your tank but unfortantlly roots dont like light so you wont ever see them..

Will you be putting blind fish in your res??? LOL....nag, as soon as one of those fish croaks, your ph woud either skyrocket, or plunge....and I would think your nutes would kill them, would be fun to see what happens if you threw a hardy goldfish in there, I know G/fish can take a lot of crap......and give it too....but serious ph problems

I am a Marine Biologist by trade, and I can assure you that not only is Aquaponics a very viable method if you have the time, money and know how to set it up, but is a completely organic nute solution as well.

The downsides are the volume of water needed to maintain the system, and the time investment you would need to find the balance point between livestock, water chemistry and plant life.

You have to take into consideration a large volume of water to house the fish, which basically will follow a 1 inch per gallon of water rule of thumb. If you need 250 inches of fish to maintain a nute level to support your plant life, than you would need at a bare minimum a 250 gallon reservoir to house just the fish, and thats not taking into consideration evaporation, and whatever the plants actually drink.

In the video posted on Aquaponics above, you are looking at probably about a 300 gallon resevoir, and if I had to guess, Id say its prolly feeding less than a 3 dozen plants, and thats if they're pushing an ebb and flow system, less for others.

To answer a few other questions:

1) Yes, you could put some guppies in your tank, or some goldfish, but yes, they will supplement their diets on vegetable matter, and the nearest supply of that is your root systems.

2) Adding flake food to the water causes PH problems as the un eaten food settles to the bottom of the tank and slowly rots. This will also cause crazy shifts in the ammonia and nitrification cycles of the water column, as different colonies of algae set up shop to feed on the rotting chemistry, namely ammonia, nitrite and nitrates, in that order. Algae in your reservoir doesn't sound good to me.

3) Most guppies, sword tails, mollies and goldfish would thrive in the reservoir, regardless of the lack of light.

This idea though interesting, would most likely fail miserably, resulting in either the death of the fish and the subsequent rotting of the animal, the food source rotting, or the animals feedding on your plants finer roots.

The uphill battle with chemistry would most likely also make this a bad nute source, unless one had available a body of water large enough to support alot of plant life, like say the size of a pond, where the unused nutes and protiens from the fish waste could be simply dispersed into the water column safely.


So in conclusion:

There is a reason the fish in the Aquaponics video are kept in a separate reservoir, and that this technology hasnt revloutionized farming across the globe.

Its simply not efficient enough to be anything more than a novelty on YouTube at this point in the game.

My advice to you is if your dead set on putting a fish in your reservoir, use a Beta, or a Siam Fighting Fish...they barely eat anything, and the wont eat vegetable matter but extremely rarely. They just sit in a corner, staring at the water surface, and hoping some blood worms fall from the sky. It wont supply shit for nutes really, but it might look cool, if you just gotta have a fish in there.

Anyway, that's my 2 pennies worth, hope it helps.

I might try this shit ... if i were to grow a plant on the top of my aquarium... would the plant stay alive or would the light kill the roots?

Not hydro , but I do know a master grower in SoCal who uses fish tank water for his soil garden. Only for veggie cycle and early on bloom. His plants are beautiful with no deficiencies ever, and his buds are sweet tasting and smelling and smoking. It takes time to master the nute load here, hes been at it for decades. Its a good source of nitrogen and micro nutes. But I can only imagine using that water and learning how the plants react and adjusting accordingly. there are many things that can provide the nutes used to grow marijuana, but it really takes time and practice and a great knowledge of the language of plants to employ these kinds of techniques.
