Should a Hayward Sense and Dispense system (AQL-CHEM) turn off the dispensing of acid automatically when the ProLogic goes into "spa mode"? My S&D reads pH too high (vs a manual test) when in system is in spa mode (e.g., 8.5 instead of 7.5), but is accurate when in pool mode. This causes the...

My Hayward Sense and Dispense system is accurate in measuring pH in my pool. Manual tests match the Sense and Dispense value. However, when the system is in spa mode, the Sense and Dispense routinely measures pH as too high compare to a manual test. I am talking like 8.5 vs 7.5. This causes the...

My elevated spa is leaking at the joint between the plaster and the coping. How do I make this seam watertight? The pool builder mason came out and attempted to apply some sort of white material at the joint, which does not look good, but did not fix the leak. They do not appear to know how to...

I have a weeping water wall feature in which water pours out of the top of the wall and drains into a 6 in. wide and deep trough that is connected to the pool. The trough catches a lot of sediment and debris and it is very difficult to keep it clean. What kind of equipment would you recommend...

I was all ready to do some pool chemistry today after some major rainfall activity. I measured the following this morning: FC: 0 TAC: 0 Salt: 2400 hardness: 250 CYA: 0 TA: 50 ph: 8 So, I INTENDED to first put in 15 pounds of sodium bicarbonate. However, instead I mistakenly grabbed the sodium...

My PB has installed flagstone coping around my pool. As they shaped it, they left chisel/chip marks all along the edges. Is this normal? I don't like the look. What did they do wrong? How do you get rid of these marks?

I'd like your opinions on the design of a pool I am considering. Let me know the things I should be on the look out for. PB wants $90K. The pool includes a spa elevated 6 feet (to patio level - my house sits on a 6 foot foundation). Spa drains into pool down rock wall. From patio level, there is...
