I'm about to add 55 lbs of boric acid if it will ever stop raining around here. (1st time to address borates; borates are at 0-1, I need 55 lbs boric acid to get to 50 ppm borates)
With that much to add, are there any suggestions on how to broadcast it across the surface? (half the amount first then test borates, a third of the amount first then measure, brushing in between, etc...)
Would it make sense to set the filter valve to Recirculate during the process?
Any other suggestions?
