I called every where nobody has any. It's is odd, I received some stuff from Oceansmotion and it all had dark grey/black PVC schedule 40. Dropped him a email and he said he can get it at most any plumping supply place in Ontario, it's common. So who knows, on the phone every one thought I was an idiot and said it doesn't even exist.
So white PVC plumping inside the tank no black.
