To seam another liner onto the existing one or build a separate new pond?

[poconojoe]

My pond has a PVC liner and the fish are getting quite large. I bought another PVC liner figuring I'll seam the new one to the old one.
What's the best way to seam PVC liners?
Or, maybe two ponds with some sort of connection for the fish to swim between the two? I guess the two ponds would have to be the exact same level to make this work well.
Any thoughts?
Thanks,
Joe

Duh! senile moment...I already asked the question about how to seam PVC! Thanks to addy1 for answering that in my previous post.

Gold lable sealant. I used it for around my skimmer box when it was leaking from the screws being stripped out.
