Assuming the pH is 8.2 ("above 8" as you say) to lower it to 7.5 for example would require 3.4 liters of muriatic acid or 4.4 kilos of pH- (sodium bisulfate).

Try to apply half the dose in two days and retest your water. If you're using muriatic acid, be very careful while handling the product.

High pH or pH drift to higher levels may be caused by an alkalinity level that is too high. Please have your water tested for alcalinity and post the results.

Allez, bonne chance!
