Hi all,
We have a 1yr old 10,000 gallon SWG fiberglass pool. I am prettty anal with water chemistry, checking and balancing every other day or so using Taylor test kit, and going by the ranges and levels suggested here and in the pool math app. Chemistry has been stable.
I drained my pool after a heavy rain - an inch lower than usual and noticed the shell is incredibly white after just 1 year.
The fiberglass company suspect calcium build-up, however I have been keeping my calcium at 200pm from the day we had the pool. The technician suggested I lower this to 50ppm and use Jacks Magic scale off to help remove the calcium.
Today I dropped the pool level to the top step, and this is almost completely white. I rubbed a small amount of muriatic acid in a small spot see if it would cut through but it didn’t really do a hugging.
I then took a very fine sanding block and tested on a small part, which seemed to bring back the blue.
Is this expected after just one year? I do have a pool heater and have read that warmer temps can exacerbate the issue. My pool is in direct sunlight all day, but I keep my CYA at the correct level, and the chlorine according to that.
Would love to hear your thoughts.
