I have a Marquis Hollywood 350 gallon hot tub. 2 1/2 years old. The ozonator has quit working. It's a bolboa ozone 3. Which as I understand they don't make anymore. From reading on your forum the ozonator has to be match to the injector tube which is blue. Any recommendations on what size or model I should purchase. There is many different models for different size hot tubs.
Thanks Bill
