I have an inground pool that looks like a really bad swamp. We have frogs living in it! We started out the season just wanting the pool people to give it a good vacuum. I live in west Texas and we had about 1/2 inch of dirt/mud at the bottom of the pool. We were having problems vacuuming it out ourselves, so that's why we called them. They finally showed up 2 months (not joking) later and they decided that we have too much calcium scale on the sides of the vinyl. We have well water that is real hard, so yes, I agree with that. They put a case of stuff in to lower the ph to loosen the scale and in the mean time, the chlorine is gone and I can't even see the bottom of the shallow end. There has got to be a better way! I found this sight last night. I consider myself a beginner, so don't assume I know much about pools. Any info will be greatly appreciated. Also, here's what I have in #s.
22 x 40 inground 10' deep
alkalinity it took 6 drops in 25ml to turn it pink
I don't know how many gallons. I forgot to use the pool calc to check
