Watervale,

My site, PoolForum.com, is focused on residential pools. Few here, besides myself have experience with commercial pools. I'll help you . . . as I have time.

But, for starters, take a full set of digital photos of your pumps and piping and send them to poolforum AT gmail DOT com.

Also, if you don't already have one get BOTH a K2006C (you need the larger one) AND a couple of K1000 OTO/phenol red kits for quick testing.

If you don't already know, on your pool, you MUST keep a good chlorine level 100% of the time..

One other key issue is code enforcement. Here locally, I'm running a HIGH CYA pool at 10 - 20 ppm, because I can't trust the staff to do what they are told. However, I have to take a 2 - 4 pt 'hit' on the code -- 2 for high Cl and 2 for high CYA . . . if his 'strips' (!!) are working well that day. However, some codes will force a re-inspection for those 'violations' which makes them a non-option.

So, tell me what your code entity is, and how you are inspected. If possible, post a link to whatever pool code you are under.
