@Mike in Laredo, ...a shade cover is a must. if you dont have leaves falling on the area, then you wont need to pitch the top, it could just be posts with shade stretched across. if you do have trees dropping stuff in the area, you will want to pitch it, or add arches.

as for what not to do....

1. dont use IBC totes.  ... use water storage tanks, the 1550 gallon water tank with the top cut off gives you a 1000 gallon fish tank for $500.

2. dont use treated lumber...its toxic.

3. dont use tilapia, they need too much heater to keep the water warm in the winter.

 4. dont put the fish tanks in the green house, this wastes growspace, put them in a building to the north of the GH. (always run the GH north to south, with the fish to the north) they dont need or like sun, and need to be insulated in the winter to stay warm enough for fish to eat and plants to grow.

 

what to do ...

1. build your growbeds out of plywood and 2"x12"s. build them at 4'x8' and use a 1-1/2" standpipe in your 3" bell siphon. you can add 6-8 of these per 1000 gal.(or gallons x's .266) then you can go to a 8'x36' raft (288sft or 144 heads of lettuce/wk)

2. use the pond liner from home depot, and use 1-1/2" bulkheads from the pool supply, not online fish supplier$.

3. use a combination of 70% pea gravel and 30% 1/2" to 3/4"crushed granite (not decomposed) for your media, this will keep your PH from jumping around.(this has to be adjusted to match your source water..i.e-if you have a high ph source water, then you need to use more granite, say 60%. if its low, then use more gravel.)

 

i could go on for days, but have to go to work. let me know if you have any questions.

Rob

Hi guys.

My name is Mike and I reside in Laredo TX.

Currently I am planning to set up aquaponics system in my back yard. A space available 25 x 60 Ft. My plan is to use a combination of growing beds and floating raft, size of a growing bed approximately 10 x 4 Ft 12 inch high, the raft container approximately 4x 30 ft. 12 inch high. Due Laredo weather I am planning to build shade cloth roof over growing area, one pump and gravity. I love to have some suggestions from experienced aquapons about system, materials and what not to do

Thanks Mike
