Your pH of 7 is the lowest you would want to be and since the FC is less than 10 there is no interference from high chlorine at the present time. I would add another half box of borax to be on the safe side.
I would also perform the bucket test to check for leaks and insepect the equipment area to make sure everything is dry there. Pay close attention to any valves and unions that might be on the equipment and the lid on the pump strainer. (anything with an O-ring for that matter).
