I built a new customized pool about a year ago and now I am having issues with the surface of the pool becoming rough. I recently checked my pool pH which was found to be 7.8. I did acid wash thrice last year. What could be the reason for such a roughness? What can be done to avoid the roughness?
Check your total alkalinity for starters.
Check your calcium level. Calcium hardness minimum levels should 250 ppm. There's a good chance the calcium is being "pulled" from the plaster and leaving a rough surface.
Avoiding these issues begins prior to the initial filling of the pool upon completion.
The water source to be used should be tested so you be can ready to treat immediately.
Careful monitoring over a 2 week period is critical.
The roughness should be sanded down to smooth and incress calcium to 250 ppm
Normal pH suggested for pools is 7.4 . If you don’t mind the Chlorine level there will scaling of pools. Rough surface is all about water balance. Regular maintenance and water refilling should be done. Make sure you refill it every 3 months. For more approach any experts in this field. They may help you with know-how on maintenance of pools.
