Hello, My pool install will be beginning shortly, and I'm planning to add a salt water generator. While my pool company had quoted me $1,400, I found the Aqua Rite 40k gallon model for $875 on ebay. I believe my pool, an 18x36, will be around 25,000 gallons. Am I safe to go with the larger model? I don't want the pool installer to say I can't use the generator I bought. Thanks.
