Pool still looks great. It's not chewing through the chlorine. But I still have a couple of questions. When "Watermom" tells me to slowly add muriatic acid, what is slowly? A quart, half gallon, gallon? The pool store printout wants me to add 3 gallons!

"Carl" says I'm almost there. If I get my ALK down to 150-180, am I still aiming for a Ph of 7.5-7.7?

Also, some people mention the pool's exposure to the sun. I live in west Texas where the sun is always shining and my pool is in the sun for the majority of daylight hours. What if I keep a bubble cover on the pool when we aren't using it? Does that help stabilize your chlorine? Once I figure out the exact amount of bleach to maintain the desired chlorine level, is it going to require more as the water gets warmer?

As always, I appreciate you moderators and your vast knowledge of pools and chemistry. I was an accounting major which helps balance the checkbook but not chemicals.
