Last year, after parting ways with a pool service that failed to show up timely, I took over the maintenance for a local club's short course 100K outdoor pool. Two new Pentair Rainbow inline chlorinators, that were just recently installed, were a total bust. Even with extenders they never could get enough chlorine into the pool. Trying to keep them filled was also nasty business.
After investing in the TF100, spending a fair amount of time here at TFP, and making The Pool Calculator my new best friend ... I was able to get things looking great and keep it that way for the remainder of the season. My go-to strategy was taking readings every 2-3 days ... and adding x scoops of Cal Hypo as needed. Low tech perhaps, but it worked out well. And because the late 60's era pool has a slow leak, requiring you to slowly supplement water over time, I never did encounter a problem with calcium levels getting too high.
This year, as we look to start things up again, I'd like to improve upon and largely automate the maintenance. The two ideas I have at present...
a) An AutoPilot SWG setup capable of maintaining a 100k gallon outdoor pool. If we can't get by with the cheaper stuff, Pool Pilot Professional could be an option.
b) A Hayward CAT 2000 or 4000 automation controller, pumping liquid chlorine and acid into the pool as needed.
I would appreciate any suggestions the TFP community may have to offer on this. The club is a non-profit, with low operating budget, and we've always had a hard time getting folks to volunteer. For this reason I'm wanting to implement a solution that is largely automated ... but at reasonable cost.
Thanks in advance for any and all recommendations!
