Aquaponics..helpful for fish?

  • We are currently upgrading MFK. thanks! -neo
Aquaponics does work but depending on what type of setup you do.

If you go with the raft/deep water culture method you're talking about you would still need a biological filter to convert to nitrates. Then the plants would use the nitrates.
If you went with an ebb and flow system then you could eliminate a biological filter and just use the growbed for your filter.
However if you have your tank higher than the growbed you'll need an overflow box like from a wet/dry filter. Because of this you'd want to stick with a raft/DWC setup to have a constantly running pump to prevent the siphon from breaking.
If you put the aqaurium lower than the growbed then you could do an E+F system with the pump pumping up to the growbed. There are ways to do an E+F with a raised tank and a constantly running pump but nothing that's 100% reliable.

If you're really serious about this check out this site. This is a Hawaii AP site.

There is NOTHING about an aquaponics set up that will lower DOC's. There is not a hobby level test kit for DOC's that I am aware of. Most of us measure nitrates as a way of gauging what the DOC's are. AFTER your tank has cycled the aquaponics will help to removed nitrates but will not removed the DOC's that are not measured. By lowering your only guage of DOC's for the purpose of avoiding water changes you are creating a cess pool and calling it a fish tank. FYI (the aquaponics will not help lower the ammonia or nitrite during the cycle, that is what water changes are for.)

Water changes are part of having a fish tank. If you don't want to change water consider another hobby.

im not doing it to replace water changes, im doing it to grow vegetables and create a safer and more natural enviroment for my fish... and i know that chances left over debris being cycled out of tank to grow bed are slim. but... why do people use algae turfs and scrubbers for? its for the same purpose right? - to remove harmful contaminates...
 
Aquaponics is used in a lot of parts of the world. Many had great success that they are now selling both veggies and fish. I don't know, but small water changes are necessary because there are other minerals left in the system that the plants don't take in. I am considering placing an aquaponic system into my pond. :) I have had some success in my experiments. Plants tend to grow faster and that means that less minerals and crap for the fish. But i recommend a combo of Aquaponics and some filtration systems. That should work.

Here's my idea

1. water is pumped out of the pond,
2. then goes to the plants(aquaponics)
3. then goes to the rest of my filter

That should work.
