What to use as an AquaSoil/sand divider?

So yeah, any ideas? Some kinda plastic I guess...?

 

As in just initially to divide it, or permanent?

When I set mine up I just used cardboard and gently lifted it out afterwards.

Use sweet jars chopped up or food standard plastics for a permanent barrier. Remember to put it in very first.

 

Drinks bottles are good too.

 

how? they are the wrong shape?

 

If you bend them they're not.

 

I've used the sides of plastic penny sweet boxes. Easy to cut and a bit stiffer than pop bottles so they stayed in place better. But I'm sure a pop bottle would work fine too.

 

i take it they have to be cut in a spiral? how do you join them together? or just over lap? how do they not curl up again? or is this the substrate that keeps it there?

 

Cut it into strips then bend it down the centre. I didn't join mine I just overlapped them so there's no gaps. The substrate and stones you'll no doubt use help keep everything put.

 

If you heat it in hot/warm water then it makes it easier to straighten it and/or shape it into the curves you want.

 

Cool, thanks guys. We've got a load of bottles left over from Xmas so that's perffect!

I was looking for a permanent solution BTW.
