View Full Version : Initial Setup Evaluation and Suggestions?

I am looking into installing a half-acre aquaponics system. I am considering a DWC setup, though not entirely sure about the amount and power of water pumps required, and PVC would seemingly be a much cheaper setup (I'm not sure if I should worry about water temperature consistency in a climate controlled, yet sunny environment). After reading around, I've also seen conflicting reports about air pumps as well. ....and everywhere else seems to leave it at "it depends."

So as is, I'm a bit lost, but still optimistic that this could be a boost to my farm's organic herb and leafy vegetable sales.

I'm on a budget, but not a strict one, and want products that will stand the test of time with minimum maintenance. If there are certain brands to look up or avoid, I would be very interested to know. I'd rather pay twice the amount for a pump that will last 4 times as long, if you get my drift.

Currently I have (chicken-scratched on a piece of paper) the following items to pick up:

2 - 10x6x6 Fish Tanks (360 feet cubed) (2693 gallons of water per bed)
4 - 1,000-hole Plant Beds (unsure of whether to DWC raft or use PVC piping with holes)
4 - 50G Drums full of pea gravel for filtration
2 - 6,300 GPH Water Pumps (26 mins on per hour)
2 - Timers for Water Pumps
? - Air Pumps for fish tank?
? - Air Stones?
1,000 - Nile Tilapia fingerlings
5lb bag - Lettuce Seeds (as a control for future farming)
5lb bag - Basil Seeds (as a control for future farming)
Plumbing to connect
1 - .5 acre Climate Controlled Greenhouse

If anyone could offer any potential solutions/suggestions to my proposed setup it would be greatly appreciated. I'm also curious what success other people have had with fruiting vegetables, as I'd fear the high nitrate content would deter growth of fruits. I'd assume Jamaican bat guano, or some other organic high-P nutrient could be added to a filtration tank during flowering?

I'd be curious if anybody could ballpark an estimate for what this setup would cost initially, and how long it would take to turn a profit on such an investment.

And finally, I'm interested in a possibility of solar or wind power that is capable of powering the entire operation, and a ballpark of what that would cost.

I don't mean to overwhelm 1 person, if anyone has any insight on anything I've asked, please just say what you know.

Thanks guys, keep it green!

I made a table of costs associated with the building... I already have the climate control in place and priced it on PVC tubing running on 2" holes, 8" centers, 10 total.... 5 stemming from each aluminum fish tank. If you see anything I'm lacking, then please let me know. From my projections I can recoup costs (including power) in 2.5 years.

Just a quick thought... Were do you live in the world?
I guess you have to have year round production and in that case would you need extra lighting and heat the fish tanks during winter?

Do you need some fans or extra ventilation for your green house? That's a big cost as well.

How are you going to build it? Hired help and heavy machinery cost a lot of money...

Go to your profile and put in your location...where you live. There may be members close by. Also, telling us what you have done to date is great, but one picture is worth 1,000 words. Post some photo and tell us what we are seeing. :mrgreen:

With that much money in produce and fish on the line, I would replace the timers with a custom programmable controller to run the timer, monitor water quality parameters, monitor alarm conditions, and relay all alarm/event messages. This would add a little to the budget, but it may save you thousands.
