Ok, need help with some questions about a SWG system for my pool. Mine is 19600 gallons, and all the systems I am seeing are rated for an AG of 18000. Can any system be used as long as it matches my capacity? I am done with Baquacil, 4 year old pool and the costs, not to mention algae problems the last two years. Ny dealer, who I think makes all his money on chemicals, says it will corrode my metal liner, but after researching this, I am inclined to not believe him.
Thanks in advance for any help rendered.
