First of all thank you for helping new members like myself. My concern is related to the change in color of my white plaster. The pictures included show a grey color that has appeared on the entire pool. On the sun deck I have spots with the color surrounding these small spots on the entire area.
The pool was build six months ago and we are in the southern part of Texas. Water in the area is supplied by the Rio Grand River and from I understand it is very hard. The pool has 17,400 gallon , it is an in ground , gunite, white plaster, in ground cleaning systems, Pentair equipment with a DE filter. If additional information is needed as far as construction or equipment I would be glad to answer.
I agreed to a bi-weekly pool service since day one in order to ensure that any issues with the pool or equipment are monitored by the same company that build it. Upon my second month of opening the pool, I was told by the maintenance crew (same as the builder) that my CYA was above 60 and CH 700 and they wanted to initiate an auto drain. I agreed and the pool water was turned by 70% from what I remember. I have a simple water kit by Taylor K-1004 trouble shooter. I inspect the water every other day and consistently get the following results: Chlorine 2.5, Ph 7.5, Alkalinity 80. I have to consistently add muriatic acid in order to keep the Ph in line. Currently CYA is at 50 and CH is at 450. I am not able to inspect the CYA and CH with my kit and therefore depend on the techs information.
I have communicated this to my builder and he has agreed to come out and inspect. I need some advise in preparation for my conversation. Is this normal? Is there a way to remove or lessen the visual impact? What changes would you make?
Thank you in advance for your help!!
