Different CYA levels for a hard cover spa?

[mckinneymagnum]

We have a new EcoSpa E-3 hard cover spa and I was wondering if this type of covered spa, that's only opened when it's being used, will that mean CYA levels should be different from a pool spa?

I just did my 2nd water change and I'm going to use the dichlor to get my CYA to the recommended levels and then switch to bleach for the chlorine going fwd, but since the sun isn't going to eat my chlorine (like my SWG pool) should I run a lower CYA?

CYA 20-30 is what you need.

Its for bather comfort when UV isn't a concern. A couple FC with little / no CYA is harsh on the skin.
