True. Need to know. I am fascinated with Aquaponics and would like to use the pebbles sifted out for the growbeds.... but if too alkaline... problem keeping pH adjusted down. Although my plants in the ground do really well in this soil. And the fish I use are best adapted to this hard water. Will see.
do you know what type rocks they are, sandstone, limestone for example, could be good knowlege if you do know and handy as well
Chert and flint are cryptocrystalline varieties of quartz. Chert is usually gray to white; flint is dark brown to black. Chert and flint are very hard and break with a splintery fracture. Chert is usually associated with dolostone and limestone and occurs as lenses, irregular layers, and nodules, but some rock units are composed almost entirely of chert....
I love building with rock. Looks so solid and enduring. When I first realised how much rock there really was here I was a bit daunted.... but now see them as a blessing. So useful. Can always say I farm rocks....
your going to end up with those beautifull old stone fences like the old English country side if your not carefull
I have never met Jennifer.... but TC knows tons more than me! It would be the other way around.
youv'e done it now, mentioning aquaponics will bring Tclynks and Jennifer looking to pick your brains and share info, both are very inyo the same subject
I have only got to design stage and laid the initial slab with AP. I have some SketchUp pics of my design somewhere if interested. I am very concerned about getting water-proofing right before I invest more time and money....because it is quite a big system. I already have the tilapia and have been testing sustainable feeds on them.... cos don't want to buy in if possible.... and love working with fish. So that part will be easy. But I know I still have some learning curves ahead.

Bird is right. I would loove to hear all about what you are doing and see photos. Tclynks knows way more than I...I am at kindergarten level myself. I have some seeds started (and growing) in rafts in my fishtanks is all. A nice indoor winter project. My house-mate says it is "like 4-H, but without the badges" around here. She is learning so many new things.
