Define it 'turning off'. Do all the display lights go off? Does the output setting reduce to yellow? If the system is shutting down output, it likely thinks the salt is low; get it checked, and carefully inspect your cell. If the display is going off, you probably have circuit board problems of...

"Across the entire organization"? I think you misunderstand. I am the pool operator; me and me alone. There are multiple locations, but only myself to deal with, who is already trained. This last year I maintained 16 pools and hot tubs spread out across 7 locations; next year may be more. During...

Thank you all for the information, especially the drop size info and the extensive math done by chem geek. For the record, 4JawChuck, I am a CPO and do not work for a hotel (Hilton is my first name), and I also found some parts of your post quite insulting. Also for the record, the pools I...

I am trying to upend 15 years of the company I work for using only test strips for water testing. To do it successfully, I need to bring numbers. I already know that our test strips (AquaCheck Yellows) cost us $10 per bottle, 50 test strips. These will last an average of 40 tests, accounting...

Numbers are fairly normal; CSI for all three locations I'm working at come in between -0.1 and 0.05. pH around 7.6, Alk around 100, no Cya, 3200ppm salt, etc.

* Edited and updated this post since I am now on a computer, and there are no replies yet. * I am in British Columbia. Even though the pools are private (strata owners only), they are considered commercial under law. The regulations from the local health authority require only a couple of...

Posting from my cell phone here so will be brief. More details later. CYA is more or less nonexistant. Indoor pools. Some might have 10-20 left over from a shock. Why painted, don't know. Probably because its cheap. pH has to be kept 7.4-7.8 for me to stay legal. I get health inspectors. :P...

Anyone have some experience with keeping tiles looking nice and clean? I'm trying to find a better product to clean the tiles around my indoor pool rooms with. I get daily white marks across all the tiles, likely from calcium or possibly salt, but I can't seem to get them to dissipate much. I...

Being oft-used pools, test results would change too often for exact results to be useful to post. However, I can tell you this: - pH is kept between 7.4 - 7.8 (usually at 7.5-7.6) and rarely leaves that range. Sometimes on Monday mornings (after no maintenance for the weekend) the pH will have...

I have a problem with brown stains at three of the pools I maintain, and I could REALLY use some help/advice on this as the pool store here has got no answers for me. This problem stems back to long before I started taking care of them. For information: - For my own reference, I will refer to...

Do people actually use these? I maintain a number of pools and I have never used one, nor have I met anyone who does. But they ARE in some of the pool rooms. Our skimmers have 1 1/4" holes at the bottom for suction, into which we directly insert our 1 1/4" hose ends. What is the reason/benefit...

I operate three pools using Aqua Rite systems. Although the system is supposed to shut down over 3700ppm, I had one pool that was mistakenly raised to 4200ppm. The cell did NOT shut down, but rather continued as per normal, although I had to drop the dial to minimum (5%) to keep the FC down...

True, commercial spas must be logged several times per day. However, the laws here are mixed; though legally defined as commercial, these pools are regarded as private and have operated as such for the past 20 years with no qualms from the local or provincial health authority. None of these...

Here are more specific details on the spas. Most are similar (almost all tiled, all sand filter, most recirculate roughly every 40 minutes, 24 hours a day). They vary in age from 2 to 20+ years. - 7,000L (1,800gal) Outdoor, tiled. Operating at 45gpm, sand filter. Bubble cover kept on. ID: K3440...

I am responsible for daily operations for several semi-private pools and spas. By semi-private I mean they are not public; they are located in retirement villas, condominium complexes, apartment blocks, etc. I took over this position only 3-4 months ago so I have been maintaining the regimen...

I used the StainFree/MetalFree combo at several of my pools when I took over their operations. Some had green staining that had been building up for years. The worst one, at 20,000 gallons (75,000 L) took five bottles of StainFree and a lot of elbow grease to completely remove the stains...
