OK, let me clarify and amend my question. We just backwashed and I watched what happened. No water went into the pool during backwashing, but when we turned it back to regular filter mode, lots of cloudy water went into the pool. We don't have a "rinse" option. Do we just need to let it backwash longer? Doesn't seem like cloudy water should go back into the pool as badly as it is. Our entire pool now looks milky and it was clear before .
