Can someone give me a good start up recipie for starting up my hottub with a DelZone Eclipse Platinum Ozonator and a Nature2 cartridge? The hot tub is about 355 gallons adn is a 1998 Hot Springs Sovriegn. I've heard all you have to do is use a little MPS for shock and thats it if youre using both the ozonator and Nature2. That just sounds too simple. I understand about ph levels and alkalinity....just a little lost on what other sanitizer/shock I might need if any. Thank you for your help.
