OK Guys, Sorry to bother you with another newbie questions so soon but alas, it is my calling! Where are the million threads that tell me how to calculate pump size. I looked around and didn't find anything, quantitative... a formula would be nice. Is there one? Thanks in advance for your time and patience.  Tony |

Size your pump to turn you total volume of water over once per hour at the minimum - at your given head height.. Most at least double it. My 8000l system has 3 x 4500lph pumps. I could do with 1 more. |

welcome, Tony on average 1 to 3 times the volume of your fish tank should be alright for your fish's health but less might be good ore more might be needed depending on density and feed rate and dissolved oxygen needs If you download my spreadsheet on: viewtopic.php?f=1&t=4150&hilit=spreadsheet (make sure to surf to the bottom of the page to download V2, the first version had some errors) you can input fish tank volume, feed rate and more and the recirculation rate should appear somewhere in the sheet have fun frank |

As you can see from the first two replies Anthony... its a bit like ..."How longs a piece of string"... Will all depend on your system layout, size of components, where the pump is located etc etc... Start with an objective... work a design that will fit that objective.... then comes the fun part... Finding the hardware to make the vision reality... most times not a problem (depending on your wallet)... some times it forces a redesign... As a general "design" rule.... note OBO's post in reference to tank volume turnover... |

Perhaps your best bet might be to get in contact with the "Morningstar Fishermen" people... They not only do what you want to do, but also work in the Central American area... Perhaps you could visit them, or one of their locations.... or S&S Aquaponics (if still open).... I think you probably need to see "how" someone is doing what you want to acheive.... And they'll be able to answer your queries as they arise... Unless you plan on living in the village you select for the project.... you need to deliver a turnkey system, that's easy to understand and manage after you've left... Reckon you need to fully understand what's involved... and to build and run at least one or two aquaponic system prototypes before you take them to the world... |

FYI Anthony.... Morningstar Fishermen courses... Quote: Our Training Programs The Residential Programs can be scheduled on a weekly basis Monday through Friday. If required, housing and board can be provided on site. Morning classes focus on in-classroom seminars and lectures on the fundamentals of aquaponics and the specific needs of tilapia and aquaponically grown plants, while afternoons are spend working on existing systems, or building new systems, focusing on the importance of hands on experience, and the importance of vigilance and maintenance in fish farming. We also offer supplemental information on, solar energy, photovoltaic and wind powered systems as well as more traditional aquaculture methods. Most importantly we offer a “hands on” experience working with fish and vegetables in working systems, where you can get your hands wet and help us with our day to day chores and activities while learning what it is really like to be an aquaponic farmer. Our Offerings We offer short term courses in aquaculture and aquaponics. These courses are designed to teach basic knowledge and the methods of successfully growing tilapia and aquaponics plants. Our focus is on simple, sustainable techniques that can be used by the back yard farmer, missionary, Peace Corps worker or any others who wish to help improve the nutrition of the poor and needy http://www.morningstarfishermen.org/education.html |
