From experience, using an ozone gas generator that has a built in air pump that turns on and feeds the ozone gas into the intake line when the pump cycles is the best way to keep the hot tub water sanitized.
The water will become very blue with ozone injected gas in it and it disallows mold and bacterial growth. If the underside of the tub is enclosed, the ozone gas also breaks the insect attraction as it kills the mold and fungus under the tub which breaks the lower order food chain and makes the area unsuitable for insect living. No need for bromine or chlorine if it's ozone gas injected. That being said, the UV lights don't work anywhere near as well as the small ozone gas generators. I've used them all and there's no comparative in the sanitation levels. The ozone gas system beats all the other systems hands down.
Water change overs are reduced to once every year or two. After you get out of the water, you can literally feel the ozone has cleaned and sanitized your whole body. Jump in with BO, climb out smelling like a fresh mountain stream.
The ozone generators with built in air pump are on EBay. They used to run for around $35 delivered.
Here's similar to what I've used in the past.

I'd inject the gas just inside the water intake so the ozone bubbles were eviscerated by the pump impeller and well mixed into the water column. It ran for about 5 minutes once every 30 minutes to hour or so depending on the outside temperature. That's all it takes. No chemicals necessary.
