So I guess I'll start with a big thank you to the members of this community for all the help I've gotten on this site. I've had a pool for 11 years, and the best thing I did was to take charge of measuring and managing my own pool chemistry thanks to the information on this site. Opening my pool is now easier than ever thanks to the SLAM process. I receive comments regularly about how nice my water looks and feels, again thanks to you all. I have decided to join so I can get some help with my wonky Hayward heater, but I hope that I can also give back a little to a community that's given me so much already.
