I hope to still have an AP tour, just need to organize it. Sounds like you would travel here when it happens. Have you heard of Local Roots Aquaponics in Tucson?

What happened to the AP tour?

I have to travel to gilbert this weekend, is it possible for me to come and see your operation?

David, Yes I know of that system, helped a friend I introduced to AP build his system with chop 2 last April. It is a good system. He pumps the water into DWC beds before going back to the fish tank, that way they are bio filtered first, but still carry nutrient water to the plants. The DWC beds are higher then the tank so drain by gravity. It is a small set up, about 350 gal fish tank, but works well. The size of the pump is what gives water movement though system.

Im using the chop 2 system, read about it, it works great.

That would be great Sheri, I actually work in Show Low.

Dave, the pea gravel clogs up by catching and clumping fish poo.

Ken, we have 40 acres up on Snowflake, but we just use it for random escapes from the city. Maybe we can get together on one of our trips up there.

Dave Sch..., I remember you on Halloween @ GardenPool! We were there that night, too.

Re: rocks--this is what I've learned:

If you're trying to keep PH low, avoid rocks like calcite, dolomite, limestone, 
marble, travertine, onyx, and slate,which are carbonate rocks based on calcium. Calcium is a metal that combines with chemicals to make salts & cause hard water & increased PH. You can test rocks for calcium by putting them in a glass with acid. Vinegar, meuriatic acid, etc. & see if it bubbles. If it does, don't use it. Never use shells or bone, of course.

Use silica based rocks, like quartz & quartzite, granite, obsidian, flint, jasper, chalcedony, and agate. Most gravel & sand around here is silica safe, but it doesn't hurt to test first.

On haloween I toured his operation for the first time, very impressive.

Ken R.,

I appreciate your comment about pea gravel, not sure how it would clog orifices?

Dave, the link to the tour you are talking about didn't come through for me, could you please repost it?  I would love to learn more about the media you are talking about.


If anyone around Tucson is interested, we are having our once-a-month public tour of our systems (with Q&A) this Sunday, 12/4 at 2pm.  Visit this link to sign up if you are interested (space is limited to 15):


We have also recently started putting together an all-day, self-guided Tucson Systems Tour, similar to the chicken coop tour the Co-op puts on every year.  We should have the info on our website soon.  The first Tucson Tour will likely be in January.  Would anyone here (in Tucson) want to be one of the stops?  The more the better.  There will likely be a small payment for participating.  Please let us know!
