I built a grow bed stand yesterday and filled two of my refurbished metal tanks with water to leak test.
Good news, stands are strong and level, GB's hold water :D

but..

Checked the GB this morning and found it rusted overnight :(

The tanks were repaired with fiberglass and then coated with bituminous paint.
I think I should have let the fiberglass cure longer before applying the paint.
Anyway back to the drawing board. I might have to line the GB's with pond liner OR take them to the dump!
Wish Joel's grow bed's were available in Adelaide !

Jezz, I'm amazed that any rust would pop up that quick..... did you killrust/treat them all over??

Good thing in one way I suppose..... Going down the liner path might be the quick,cheap, easy way.

Yeah we spent a lot of time and effort trying unsuccessfully to seal one of the bigger GBs with the bitumen paint, after many mant hours and $ in paint we ended up getting a liner, seemed much easier. The other GB we perservered with painting still leaks, altho no where near as much as it did.
Go the liner!

I put sikaflex on the joins before the bitumen paint, on the big tank it has worked well. The big growbed is actually the lid of the tank and has a corrogated floor/roof. That's why we had so much trouble getting it to seal.

The corro growbed has only one tiny leak and a bucket catches that and the water goes to the raspberries :D

Pete, did you use a scrim (material) embedded in the black stuff?

Yep, hole saws and acrylic.
I needed one extra rubber washer between the PVC and acrylic to get a perfect seal.
