The backwash water flows out of a pvc right at the pump...it is easy to see and there is no water leaking from there.

The water is about an inch below the little arrow on the skimmer (middle of skimmer) that indicates where the level should stay. I was about to convert to BBB from Pristine Blue so there is no chlorine in the water yet.....just minimal residual of Pristine Blue. Should I fill it back up to the skimmer line and get the bleach started and chemicals balanced and then worry with the leak or go ahead and let it drop all the way past the skimmer (another inch) then refill and start on the chemicals.

Sorry to keep asking so many questions....I feel like my head is spinning
