Building Plywood Tanks
I get these 40"x47"x36" plywood boxes from a juice factory for $5.00 each. I cut the shipping boxes into thirds or in half, and add bottoms to the sections as needed. I look for discounted irregular plywood to save money (generally 1/2 price).
To build the basic plywood box would cost about $60 if you used 3/4" plywood at about $25 per sheet. These come banded with heavy metal corners.on a pallet. Its hard to beat these juice boxes built with high grade 3/4" - 5 ply plywood. It takes about 2300 ml of resin per tank at $50/3.5 liters

| Fiberglass makes these tanks durable and clean. Cost was about $60 per 40"x47" tank. |
 |
| Im filling this tank with water to test for leaks |
 |
| The deeper tanks on top will be wicking beds. The shallow 12" tanks underneath will be bioponic grow beds. |
Im not concerned about toxins from the fiberglass resin. If you are then use LG-730 Mono Epoxy Pool Paint or Pond Shield. for the finish coat It will add $10-$20 per tank
These same tanks would cost only $20.00 each if pond liner were used.
Box - 5/2 = 2.50
Liner - 100/9 = 11.00
Bottom - 12/2 = 6.00
After one year of use I found that the bulkheads needed to be tightened. I expect the wood expands and contracts with changes in humidity which eventually caused them to loosen.

Quote of the day
While reading through the AP (aquaponics) forums this morning I came across this from Vlad. It made me laugh. Vlad has a way of hitting the nail right on the head. This was in response to a questionable ad -
"...Well, OK maybe its even a bit less hokey...somebody please just shoot me in the fucking head if I ever start rambling about how some overly priced, energy intensive AP system is going to feed some poor backwater village in the middle of the African desert...I mean its nice for middle class white folks to have a feel good hobby and all, but when folks use the very real and legitimate suffering and misfortune to tug at the heart-strings of Mr. and Mrs. Jones of Lakewood in order to sell them something...it kinda gets my goat. Sorry for the rant..."
Vlad and I are on the same page concerning AP. Quoting Vlad again (sic) "Aquaponics is a romantic attraction".
You may wonder where my allegiance lies. This is of course a blog about aquaponics. I do like aquaponics, but its not the only way to garden (Bioponics or Wicking beds may better suit your needs), and by no means is it cheap or as easy as some would have you believe.
A well managed AP system can out perform a soil based garden, but well managed is the crux of the matter and the term that requires definition.
In any case dont let the lure of technology lead you into grand ideas of easy profits and abundant crops of fish and vegetables. It may not be rocket science, but it is a science that requires a fair amount of attention.
