I posted this question because i could not find a answer on the Board
I've been told by TFP not to worry about low Total Alkalinity
On the WWW it says otherwise can some set me straight on this?
this is what i found :
PROBLEMS RESULTING FROM LOW ALKALINITY: If the Alkalinity of your pool is too low, these problems will occur:
* Dissolved metallic parts of your pool (walls, floor, hand rails, ladders, light fixtures, and equipment). This could even lead to discolored water or stains on the pool walls and floor.
* Stained and etched concrete in concrete pools.
* Stained and etched plaster in gunite or shotcrete pools.
* Stained liner in vinyl-liner pools.
* Blistering or delamination of fiberglass in fiberglass pools.
* "pH Bounce." Alkalinity acts as a buffer for pH. If the Alkalinity is low, the pH will fluctuate dramatically. Yesterday, it may have been 7.0, and today it may be 7.8, and tomorrow it may be 6.8-it can change from one extreme to the next, literally overnight.
* Minimizes the effectiveness of chlorine (or its alternative).
* Eye and skin irritation.
