Thanks for the tip, BuiDoi. I may very well do that with my second IBC, which will become the next two GB's.

After plumbing, planting, cycling, fish...
:)

Exciting stuff, congratulations!
I have a piece of landscape fabric soaking in my sump tank if you want it for kick starting cycling. That and the rinsing rack are yours to use.

Excellent, thanks Nate! I *think* I could use the gravel rack later this week, but seems to me that I will need to have my system plumbed and pumping before I take the cultured landscape fabric?

Sure seems to be about time for a Sacramento AP tour! (Although that's a topic for the NorCal thread.)

I had a bit of trouble finding this, so I'm pasting a link to the flow versus head ratings for Laguna pumps. Click on the Specifications tab, about halfway down the page.

More links to helpful info I'm using in my system design:

PVC pipe dimensions, nominal, inside, and outside diameters.

TCLynx has some updated suggestions on the Oft Repeated Rules of Thumb thread. I plugged some of these numbers in to Dr. Lennard's calculator, and TCL's numbers are on the high side (but within bounds) of his suggestions. These seem very reasonable as maxima, so I'll probably aim for lower fish density.

TCL also has Uniseals for sale, along with helpful info such as required hole size. I'm probably going to have a 250-300 gallon FT, so I want to run at least that much water through the system per hour. FT will be gravity drained via SLO, so the drain pipe at least 1 inch nominal. (I need to find the link to the plumbing post!)

Fishless cycling to establish nitrifying bacteria without risk to innocent fishes. ;)

I may change my design to http://www.backyardaquaponics.com/forum ... 03#p290803
It would address a few concerns I have. First and foremost, gravity flow from thr FT to the GB's -- Obviously gravity flow will happen, but I wonder about balanced flow (both liquid and solid) to each of the GB's. It seems to me that the valves will inevitably get clogged with solids, whereas a pressure flow would be less prone to this.

The downside of this approach is solids entering the pump, but I think fish waste should pass through the impeller easily.

Perhaps I'm worrying over nothing...

And Stuart (a few posts after the link above) mentioned using a temporary elbow to check for balanced flow.

JoC has dressed up her IBC's very nicely! I think my wife would be much happier looking at something like this:
viewtopic.php?p=497625#p497625

Just a reminder to attach the rails first:
viewtopic.php?p=403882#p403882

And make sure any top/lid is removable!

TCLynx on pH buffering, she suggests checking homebrew and winemaking stores for potassium bicarbonate.

Hey thanks for the nice words JimV. I like my rustic old fence palings which go with the rusty found objects and metal art around the yard, but checking out more and more members' systems, I am in awe of their inventiveness, skill and creativity and more than a bit envious.

You better not show your wife IceMan's feature AP system - I have serious cladding envy! viewtopic.php?f=18&t=23141

Or Dogdoor's amazing inner city courtyard system viewtopic.php?f=18&t=15481&start=180

Just a tip, work out how many screws you need to attach the palings and buy a bulk pack! I am glad I screwed rather than nailed, as several palings have been on and off for plumbing and running leads etc.

Good luck with your build

All along I've been planning to put this in a temporary location, while I work on clearing out and leveling the far back yard where I'll eventually set up my (strke)final(/strike) next AP system. My problem is I keep thinking about my future system, and this temporary system succumbs to "feature creep", getting bigger and more complex.

What I *really* need to do is just get a simple, TEMPORARY system set up and begin cycling. So I think what I'll do for now is just put my IBC growbed atop my fish tank (a 1000 L stock tank), pump straight out of the FT into the F&D GB. No ST, very simple plumbing, and the water level won't fluctuate drastically with only about 100 L in the single GB. FT will only be stocked with mosquitofish for the time being.

The growbed is going to be much higher than I would prefer, but I really want to get this thing running soon, so I can get back to work on the rest of my back yard.

Thanks for the tips, JoC! I haven't looked at Dogdoor's system yet, still weeping over the beauty of IceMan's masterpiece. I'm not worthy, I'm not worthy! :notworthy: (And no, my wife will NOT be seeing pictures of that if I can avoid it! :shifty: )

And TCLynx recommends getting potassium bicarbonate from a homebrew store. I'll check later this morning when they open.
