Welcome to our forum.
I don't have my tub yet but I ask the Jacuzzi dealer about different sanitizers and when I mentioned hydrogen peroxide he told me it would void my warranty , Jacuzzi claims (don't know if its true or not but its their tub till the warrant runs out ) that hydrogen peroxide dries out the seals and causes leaks down the road after time.....

Hog wash, dealer can sell what they want as far as chems. Might be in the small print somewhere I have just never read it. But they do use the same gaskets or made of the same material anyway as everybody else so it would probably be fine. Least in my book I would cover it and not look for an excuse as to why something failed and push it back to the consumer for a reason not to cover it. All that said I would not use hydrogen peroxide as a sanitizer.
As for hydrogen peroxide wear on hot tub components, see this post, this post, and these posts. Also, this manual ("Please avoid using any spa chemicals that contain Hydrogen Peroxide. Hydrogen Peroxide based spa chemicals have been found to react adversely with the materials used to produce these components.") and this manual ("Alps Spas strongly discourages the use of chemicals that contain Hydrogen Peroxide. Hydrogen peroxide will eventually cause the light body and lenses (used on all spas) to become brittle and crack.").
Thanks Jacuzzi Jim and Chemgeek for the responses. I have found with a TA any greater than 30 my PH shoots up with any significant aeration in the tub. Unless I’m missing something, I don’t think I can have my TA any higher than 30. As for borates, yes, I am using 50 ppm from boric acid. As for my sanitizer, I’m using hydrogen peroxide. I know that’s not the normal way to sanitize but so far we really like it.
