I ordered a bucket full of InTheSwim chlorine tablets. I've used other brands before without this problem, but these guys seem to be incredibly reactive to the skin. Each tablet is enclosed in plastic, but when opened, the slightest amount of dust that gets into the air vigorously inflames the...

I'm pretty familiar with the types and operation of control systems. However, I don't have clue what kind my pool has or where it might be hiding. I'm guessing it has some type of ball-float level control, but I don't know where it is. Any suggestions on where to start my search? What are the...

What are the factors that cause pool water to end up with a high pH. I'm in Arizona (yes, it's hotter than [never would have dreamed that was a "curse" word, especially in view of the fact that my brother lives in [curse word] Michigan.]) with an 17,000 gallon IG pool (fresh water, sand filter)...

I've been caring for my pool water for a couple of years. It's normally so clear, you have to look twice to be sure there's water in the pool. However, when it rains heavily, the pool takes a hit. About three weeks ago, I had an algae bloom - not too bad - but bad enough. The chlorine level was...

Are there any simple, but effective temperature monitoring devices that provide a remote readout capability, i.e., wireless or "magic"?

I have a pool cleaner. The filtered water is returned via jets near the surface at the pool corners. But the system also include a spray of water onto the surface (see the picture). If it was a sewage pond, the spray would be for aeration. If it were a diving pool, it would be so divers could...

I'm a relatively new owner of a relatively old pool. It has a Haywood Pro series - S311SX sand filter. I finally let the pool guy that came with the house go so he could expand his horizons on someone else's pool. I replaced the pressure gauge on the sand filter and it never changes. Always 18...

I've got a 16,000 gallon pool, sand filter and vacuum system working off a 1½ hp pump at 3,450 rpm. The guy at the pool equipment store said the rule of thumb is to run it for one hour per 10 degrees of temperature, e.g., 100° day - run it for 10 hours. Does you thumb look like his? Any other...

I'm relatively new to the pool world and it seems everyone from my barber to the baker insists a variable speed pump is much more cost effective. However, given my simplistic reasoning, it doesn't make a lick of sense. Please help. Assuming the purpose of pumping the water through a filter is...

I'm a newbie to pool maintenance, but I'm a chemical engineer. With that said, more out curiosity than anything else, I'd like to understand the behavior of CYA. I keep stumbling across posts that say if the CYA level gets too high you can't maintain adequate levels of free chlorine. However, if...

I'm going to take over my own pool maintenance and would like a "good" book on pool water chemistry. I'm an advanced degreed chemical engineer by training and would like something more thorough than the standard "dip the strip and add a bucket of chlorine". Is there any book out there that...
