Hi guys, I'm in a bit of a jam and would appreciate your help.
I just got a maintenance gig at a local hotel, and this is the problem...
When I took over I had a total of about 15 min training on a pool/spa setup, and
pool school isnt for a few weeks yet.
Last week we had a huge body count... between 50-100 bodies per day on Sat/Sun, followed by at least 25 a day since. The ORP levels bounced up to 900, and I tried to shock it and got my butt kicked.
So I drained 19,000 gallons to start fresh Mon Morning.....but I still don't know diddly. I know the incoming water will be 40 degrees, Ph= 8.4 and I think the CC on arrival will be 3-4ppm. (from last weeks spa draining)
How do I fix it ASAP to get it opened back up???
BACKGROUND: 19,000 gal plaster in ground pool. Large sand filter I'd estimate 45 gal or so?? 2In inlet. Large pump(maybe intelliflo), drained it in 4-1/2 hours. Watermatic C-660 ORP/Ph controller, and we use 12% hypochlorite liquid as well as muriatic acid through the controller.
The guy I took over for said he never shocked the pool, but would on occasion throw a couble of tabs (84%) into the skimmers. I assume I should plan this differently??
Any help or advice would be great, I'll check the forum from work & see what it looks then (if its done filling yet)
