You should not have any problems. 24hrs is not a proble. as soon as you have your tub hooked up, turn it on and add your chems. then look at it inccesantly while it heats up. Enjoy your favourite beverage and then about 10 hrs later, hop on in and melt away.
Congratulations on your Optima, it is a great tub. If you can woul d love to see pics of your installation.
