We're in the middle of a new pool build. We plan on hiring a pool maintainer once it's finished, but I would prefer not to blindly trust this large investment and my family's health to the care of someone else. I would like to develop a fairly deep understanding of water chemistry and pool maintenance. TFP has been an excellent resource, and the "Pool School" forum is particularly helpful. I'm wondering if becoming a Certified Pool Operator might also be worth the expense? Has anyone taken the course just to maintain their own pool?
