High TA - new to SWG

[swanny]

As the subject says I have a TA of 150.

From my reading as the swim season go's by the SWG will slowly raise the PH, at which time I add acid and will end up lowering my TA & PH. Is a high TA going to cause issues with the SWG? Everything else appears to be in-balance.

Other random questions
The pool is crystal clear during the day. At night I can see a haze with the light on.

Other than that I have the SWG set to 13% with a 24 hour run time ( Is that high? FC seems to sit around 4.5. With a T-15 cell ) I do have an autocover so the pool has been closed for the last week.

With CH close to 300 and a SWG, I'd like to see TA around 70 to avoid scaling in the SWG cell. As far as the cloudiness at night, try increasing you filter run time although this is a con when it comes to sand filters...water clarity differecnes can be seen at night with a pool light on. Adding DE to the filter may help some, but not sure

Since you have an autocover the CC is expected and opening it for a few hours on a sunny day will knock that out.

The haze you see in the light is just a product of having a sand filter. They don't filter as fine as a D.E. filter so with the on light you can see the tiny particles floating by.
