Looks like Teflon was used.
The blue glue seems to be an attempt to

You're totally right because I was the one who tried
the blue stuff a year or two ago to stop the leak.

Needless to say, it didn't work.

Interestingly, the blue PVC glue didn't really stick
at all to the (probably ABS) black pump plastic. It
flaked off easily - and you can see it didn't penetrate
to the fitting threads in this closeup photo which
was taken before I flaked cleaned it off the fitting.

I called Sky Blue Pool Supply, who suggested "Plumbers
Silicone" at $7/tube as the pipe dope for the fitting.

Googling for what that really is, I find a confusing
array of plumbers caulk/putty/sealant/grease/silicone terms.

I called The Pool Guys, in Saratoga, but they weren't open
yet. I'll try Leslie's when they open at 10am but you never
know what you'll get from them.
