If you use a test kit and your chlorine level is high I would say no, let the filter run and while the filter is running vacuum the bottom of the pool to remove some of the mud off the bottom of the pool floor and check the filter for high pressue, so the filter can do its job and get the pool clean. You want to keep your chlorine level above normal during the cleaning level so when the pool is clean your are ready to use it, also I do not know how brown or muddy the water is.
