I have a 1993 CalSpa classic vip model that I have bought used and have no idea how many gallons it takes to fill.I would like to know so I have a idea how much chemicals to use etc.I am new to spas and I am just getting ready to fill for first time. It is 8x8 and I believe it's a 6 person tub. Thanks for any info!!

Based on what you've stated, I'd guess... minimum 450 gallons - max 550.

I'm sure this is pretty much in the ball park of what you have.

But if you want a real number, I'd say 490. Heh Heh... works for me.

Thank you for the fast answer! I now have a rough idea where to start out with the chemicals. Thank you
