biological aspect of bacteria
 

Hi Ron. I'm working on a report for one of my classes. I need to know what the biological aspect of bacteria are in a hydroponics unit. Or, How will the bacteria help the fish? Can you help? Thanks. Natasha

I would go to aquaticeo.com and ask for their catalog. They specialize in fish farming and hydroponic equipment and you can lean a lot from their catalog.
You can build your own aquaponics garden by placing the 11 Plant Garden without the container on top of a fish aquarium. Don't use the ebb and flow method but instead you need to run 1/4 inch spaghetti lines from the submersible pump in the fish tank up to each bottle/plant. This drip method doesn't use as much water as ebb and flow so your fish wont be sucking air ever time the pump comes on. You need to filter out the fish poop after it has release its nutrients in the water. Remove the old fish tank light and add a grow light above your garden that will serve duel purposes for plants and the fish.
Don't expect to grow high users of nutrients like tomato plants but stick to growing plants like bibb lettuce.
The problem is hydro plants like a pH of 5.5, 6.0 and fish like it at around 8.0 so you will have compromise on that and put it at maybe 7.0.
