How do I keep my chlorine levels up with a SWG?

Thank you! Put that in the calculator and 100% @ 8 hours = 2.8...

Yeah you’re gonna have to run it longer than that in the peak of summer. As mentioned the average fc loss in an algae free residential pool is 2-5ppm/day give or take conditions.
What kind of pump do you have?
Single speed, 2 speed or variable speed?

Single speed. Asked my pool guy last year when the pump died about multi-speed and he said it wasn't worth it. I was skeptical but at the time I just wanted an end to the problems

When you depend on it for adequate chlorine production it is certainly worth having a vsp. I have 2 good single speed pumps (1 on the pool & a spare) & I am seriously considering a vsp in the near future as it would save me between $500-$600 a year on electricity.

I am hoping my pool gallon calculations are off. The previous owner had the SWG set with a capacity of 33,000 gallons. I'm open to replacing the SWG as it's not even sold anymore but I don't know what SWG can handle ~80k gallons

What are the dimensions of your pool?

You don't have 80,000 gallons and I doubt you have over 40,000 gallons.

You have 32,000 - 35,000 gallons based on my calculations. You have three rectangles:

  • 16' x 16' x 3.7' = 5,700
  • 20' x 20' x 3.7' = 11,000
  • 20' x 20' x 6' = 18,200
Call it 35,000 gallons maybe a bit less with the steps and the hopper sides.

There's 3 different depths, one is 8 feet and the other 2 i THINK are 3 feet and 3 foot 8

The 8' hopper has sloping sides.

That's why I said it may be more like 32,000 gallons.

Definitely not over 40,000 gallons.
 
Do chemical addition results coincide with Pool Math numbers? That is what I would use to confirm the amount of gallons in your pool.

Example: Measure Ph currently, then use Pool Math to determine how much Muriatic Acid it would take to reduce Ph from, say 7.8(or whatever Ph you measured) to 7.4, and after testing Ph after acid addition see if Pool Math agrees. If not, then you know if your estimated gallons are high or low.

+1000 for speed stir - it’s a once in a long while investment that lasts foreve and is a godsend during heavy testing and for accuracy as well
