Backwash for longer
We advise that you backwash your pool a little longer each week, to lower the water in the pool by an inch or two, and then topping up. This keeps the efficiency of the minerals and chemicals to a max. In an ideal world a pool would be emptied every couple of years, but this isn’t always practical or economical, so keeping the water refreshed using the backwash for longer method is a realistic solution.
