  1. Just curious, I had to change out my bulb in the pool light housing, (did it no problem) what is to happen if water was to leak through the seal and reach the bulb, obviously water and electricity dont mix, is there a special shut off switch besides the breaker that would shut off if water were to reach it?? Would anyone be seriously injured if water were to reach it (death) dont want to sound stupid but electricty scares me to death, not to mention when its that close to water. Any insight would be greatly appreciated, thanks! !
  2. thanks so much for the detailed information, its much clearer now thanks to you, I know you have posted this info before, I tried searching for it but couldnt find exactly what I wanted, sorry for a possible "re-post"
  3. Trying to get some clarity here?? I was under the impression that sodium bi-carbonate raises alkalinity, not pH. Sodium carbonate (soda ash) raises pH, not alkalinity. Acid lowers pH if "pooled" and acid lowers alkalinity if its poured directly into the pool in a "funnel" technique??? Is this information wrong? Which would be the ideal way to balance the water if you have a high pH and a low alkalinity reading? Just a few "chemical" problems I have been fuzzy on, thanks for any help yet again guys (and gals)!!!
  4. It is not vinyl, its plaster. This has happened a few times before, and everytime it goes away by itself within a few days, very strange. The pool does have a heater as well, other than that the pool is flawless when it comes to stains.
  5. Whenever the "undissolved" Cal-hypo settles and rests on the bottom of the pool, it creates a black stain, only where the cal-hypo sits, no where else. Im assuming its from metals? Related to a heater? Whats weird about this "stain" is that after about 24-48 hours the stain(s) completely disappear as if it never even happened? Can anybody tell me why this happens?? Thanks in advance!
