Hi I am new to swimming pool problems after having had a trouble free 4 years,then about 8 months ago i started to notice staining to my pool floor.When i took a closer look under the water i also noticed that the pool was starting to become pitted in the area of the stains. This area is mainly concentrated in one half of teh pool with no marks or pitting to the Spa? My pool is still under warranty and i have had them take a look at the pool and they tell me that it is a Stabilizer problem that has caused this? Seems strange that there are only localised stains and none in the spa. Could this bee the steel bars used to construct the pool, and not enough lining having been added?
The builders sent some one round who added "Jacks Magic Stain Solution #1".Whilst this did remove the stain it has done noting for the pitting.I'm worried that this will continue and the pool will go out of warranty
and i will be faced with a bill for having my pool re-surfaced.
I had the water tested . Would really appreciate if some one could help.

Pour this solution towards he deepest part of the swimming pool while circulation system is operating. Do not add more than 1 gallon of
Muriatic acid per 8 hours. BE CAREFUL WHILE HANDLING MURIATIC ACID, IT CAN CAUSE SEVERE BURNS AND DAMAGE>
Recheck PH 24 hours after total alkalinity adjustment.
