I found a few inexpensive IBC's, so I'll try diving into AP with those. And since we all love pics, here's my pathetic attempt at Google Sketchup:

This is very similar to my first design, just using an IBC for the growbed (top 30 cm) and sump tank (bottom of the IBC).

I think the IBC GB may be a bit smaller than originally planned, and certainly the ST will have quite a bit more capacity. As soon as I get the IBC(s) cut up, I'll take some measurements and update my system spreadsheet.

In the meantime, anybody have any feedback for me?

Excellent design,has been done many times with no issues,but how about and this is just a thought,do away with the sump and make another grow bed,then have the fish tank and grow beds the same height and then airlift the water within the system,two 3/4 inch pipe airlifts will flow 1000 liters with ease. If it was me i would pump into the fish tank via a collector that is fed from the two grow beds,bottom drain or SLO from the fish tank into a RFF then onto the GBs.

Thanks! Actually my plan is to add several more GB's, once I've got my system cycled. I thought this initial system would be fairly quick, and hopefully easily expanded.

My first expansion would probably be another IBC, cut into two additional GB's. So assuming there were 3 GB's, would you advise any differently?

In that case i think you would be better with the configuration you are already planning as it well tried and tested,larger systems are better using conventional ways.

But it's gotten dark on the drive home, so I'll have to wait until tomorrow to start hacking the first one up.

Ooh! Nice and shiny still! Where'd you get 'em? (cough) what was in 'em?

I still have a 3' x 6'-ish(fits small pick up truck bed) rinsing rack for gravel on hand, if ya could use it, say the word.

Just wait till you put the first drill bit through one of those totes. Saying "I Do" was a no brainer commitment by comparison.
Cheers!

Nice! Now the work begins. Get ready for some manual labor Jim because digging sumps and washing media is A LOT of work. By the way, what type of media do you plan on using?

A place off of Florin-Perkins Road, near Blue Collar Supply. I left their business card out in the truck, post it tomorrow. $99 each! They've been used once, for some kind of organic sugar syrup.

Yeah, I would *love* to borrow your gravel rack!

I got some LECA called Hydrocorn XL, http://www.goldlabel.nl/91/Hydrocorn.aspx
It's 16-25 mm I think.

Oh, found the post about the IBC's!

I posted on the NorCal thread, seeing if I could get some water from a cycled system to jump-start my new system.

If you can't find anyone then your welcome to some of my water. My system is only been running about 7 weeks so the chemical and bacterial levels are not going to be as good of quality as a system that's been running for several years.

Thanks, Max! Well, you're at least 7 weeks closer to a cycled system than I am!

I spent the weekend doing a lot of landscape prep -- some of which was even AP-related. But the real AP work didn't begin until the last few hours of Sunday afternoon. I yanked the liner from my first IBC.

These previously held a sugar syrup, and it's readily apparent. Super sticky! Fortunately, even though it's still technically winter, it was 24C in Sacramento today, so perfect weather for washing off an IBC.

Now that's done, time to get the Sawz-All!

I'm going to use the base of the cage for my grow bed, and the top of the cage will support my sump tank. I wanted the GB to be approximately 12 inches/30 cm tall. The second bar on this cage is about 14" from the base, which is close enough. But I also want a ring/bar around the top of my ST, so I cut the cage just below the second bar.

I dialed the speed down to minimum on my Sawz-All, to prevent the blade from melting the liner instead of cutting it. I had a heck of a time cutting the liner with the reciprocating saw because the liner and saw kept bouncing so much. But after a moment I realized that the trick was to only cut on the side facing up, and keep constant downward pressure on the saw and liner.

I was amazed to find that the inside of the liner was *much* cleaner than the outside. All the inside needed was a quick rinse. So I've now got my ST and first GB ready to plumb!

But before I do anything else, I need to smooth off the devilishly sharp edges and burrs where I cut up the IBC cage. Off to the hardware store for a deburring tool, and that'll probably be it for this weekend. But thanks (?) to Daylight Savings Time, I will have an extra hour of daylight after work. Progress!
:cheers:

The only thing that I would do differently, NEXT TIME, would be to make the GB's from the SIDES of the IBC..

Works out about 10% bigger..

Now that has to be worth having to use timber or similar to hold the sides in.. :-)
