VicTub

Hello, I am new to the forum. Lots of info! Thank you!! I have a new ecospa 230 gallons. It has an ozone generator. We like to use it everyday. We are a family of 4. I do not know much about maintenance, so this forum is really helpful. The sales guy told be to just use the "eye test" which is just to look at the water and if it's cloudy put some chlorine granules in... a couple tablespoons. I was led to believe that the maintenance was super simple.. I am finding out that there is more to maintenance. So recently the tub has begun to smell and looks a little yellowish. I shocked it a few days ago and the yellow and smell are back again. I am a newbie, so be gentle with me. I see that others have recommended the taylor kit. What else do you recommend... especially based on the yellow smelly water?
