    Penthouse Aquaponic System

    Hi, I live in the caribbean, on a penthouse apartment and here is my Aquaponic NFT System.

    - 30 gal pond
    - one 4 in diameter pvc tube, 20 feet long - top
    - one 6 in diameter pvc tube, 20 feet long - bottom
    - Started the system in January 2010
    - Plants in the system: 16 lettuce, 13 tomatos, 3 garlic, and 3 chives

    Latest test to the pond:
    PH: 7.5
    NH3: 0.1
    NO2: 0.0
    NO3: 13
    Temp: ºF 87

    So far everything is running smooth. Plants are growing very nice. Fish are very happy.
    Goldfish and Koi's is what I have in the pond.

    My goal is to go bigger so y can grow tilapia in the pond.

    What is a good size pond to grow tilapia?

    I was planning to go for a 125gal pond. Is this big enough to grow some tilapia? How many of them?

    Thanks.

    cool, looks very clean.
    Are you using any filtration, since nft's have no rocks?

    I have a 100 gallon tank and was told my system could easily hold 25 grown tilapias.

    You could easily start out with 50 small fingerlings, but as they grow older, you would have to get another tank .... 1 gallon of water per pound of fish is getting right on the borderline ..... and that's with excellent filtration, etc. 3 gallons per pound is more like it ..... BUT, since you are using growbeds, if you have 250 gallons of growbed to a 125 gallon tank, you should be OK with 1-2 gallons per pound, provided, of course, that you can keep the fecal matter separated in a sump of some kind. I think that's what caused my biofilter to go TU, too much feces being sucked up into the biofilter .... a sump is my next project something along the lines of what Dufflight was showing us here Clik A swirl filter, with a tap on the bottom to drain off the feces. I've got a 15 gallon plastic barrel doing nothing, that might just fill the bill. Another project to go ahead of my FT

    No, not using any filtration for the solids. Both tubes have gravelle so it stay mostly at the water outlet en the top tube. I left the last hole onthe tube open and didn,t fil it up with gravelle.

    Do you think I should use a filter with this small system?

    Next time I will be posting a photo of my new dsign for the 125 gal. Pond System.

    Thanks so much for all your good coments and help.

    If there is gravel just throw some compost worms in there to keep the solids from building up. In most AP systems a media filled grow bed gets rid of a lot of the solids from the fish.
