Ok.

I had to look up the CPT -- it appears that's new this year, and is the brainchild of a "Tom Donaldson" about which I can only discover that he's involved with the APSP. I can't find any other information about him, so I have no idea how knowledgeable he is.

Let me make two suggestions:

1. Read the Best Guess page, linked in Janet's (aylad) blue signature bar above. That is CRITICAL information for you.

2. Read Chem_Geek's corrections to the CPO manual, here: http://richardfalk.home.comcast.net/...uggestions.pdf


I'll further make this observation: there are only 3 possible ways I know for you to keep the sort of pool and spa you describe sanitary, during high use periods:

1. Install ORP/pH control systems on BOTH the pool and the spa, with bleach and muriatic feed using carefully maintained pumps. Check and calibrate these at least 1x per week. (SWCG's could be used instead of bleach feed) OR

2. Test and adjust the pools 2x daily during low load periods and hourly during high load periods.

3. Run the pool and spa with VERY high CYA levels, and correspondingly high FC levels (per the Best Guess page). Caution: depending on bather load, this may NOT be sufficient with the spa.


*** I will not help you 'get by' in the typical hotel/motel/apartment complex manner. Those pools are almost NEVER sanitary. ***
