Ok so we have a 20 x 45 x 36 L shaped pool in the planning stages and I’m trying to figure out which SWG to get. I’m getting the kit from discount pool and they offer the Hayward Acu rite. But I’m not sure that’s big enough. I think my pool is 45k gallons and they’re largest system says 40k. Also, when people say automation in reference to salt systems, what are they referring to?
