Well done Petesake. How does the HDPE plastic feel around the stretched areas? Does it feel at all brittle?

Well done Pete, it's a lot more concaved than I thought it would finish up, I can't wait to see how it performs, I'm sure it will work a treat and you'll have a lot cleaner tank. :notworthy:

You could use expandable foam underneath for support, just box the metal cage base up to take the foam, put a bit of water in the bladder to keep the shape, squirt the foam in and you'll have solid support over the whole base. You could use a bit of Gladwrap on the bottom of the bladder to stop it sticking if you ever wanted to remove the bladder later.

Thanks Guys.

The factory temp has been 14-16*C but because of the shape the IBC seemed slow to cool so I let it cool down overnight.
The conical shape has rigidised the base although I can by hand push the apex through to the inside... if there was any reason we wanted all the muck on the outside edges and corners :thumbright: . And yes I think you could use it as a mould for support material. The PE doesn't feel any different when pushed around still kind of flexible but strong.

The next task is to attempt to create a 50-60% tapered base on a spare FT in the fish house.
