Bulkhead fitting with a plug would be easiest.
Oooo thats nice!! Gumtree?
I would get a hole saw bigger then the pipe and remove that way, then attach a new bulkhead fitting, Id imagine you will want one at the least to act as a valve for easy water changes and having 2-3 more for returns and draining cant hurt![]()
Quite cute how small that pool looks now lol.
Awesome, makes that intex pool look tiny!
Wow this is going to be a fun project! What was the tank originally used for?
