I have 2 problems. I went to clean my hot tub and there are thousands of little rubbery white things floating in it. Like if you put part of a callous in the water and it got slimy. Does anyone know what this could be? So I put in my chemicals and turned on the jets to stir things up and the fuse (SC30) blew. I got a new fuse and it blew the next day when I put the jets on. Does this sound like a wiring problem? Thanks for any help.

No clue what you just said there...but...

slimy white things, not likely to be a component of the hot tub. Black, possibly, hard white things, possibly, other than that, your guess is as good as anyone's.

A fuse blowing when you turn on the jet pump would indicate a shorted jet pump.
