Safety concerns. Always marinate meat and fish in the refrigerator. You can use some of the marinade for basting after removing the meat or fish from it only if you bring the marinade to a boil and cook for five minutes to kill any bacteria.
Running the pump at night should only be when you are doing a major chemical treatment such as algae clean-up. Your pool is more vulnerable during the day, plants don't grow at night the way they do during the day--that's true of ALL plants including Algae.
1 You may also want to add a high quality algaecide to the water at this point. 2  Run your filter 24 hours a day and backwash 3 or 4 times a day for quickest results. 3  Green or cloudy water will quickly clog a filter, therefore you may have to backwash your filter many times a day until the pool clears. The pool will never clear up if the filter is not working properly 2  ! Once the water does clear up, you will most probably see debris on the pool floor (dead leaves, algae, etc.). 3  If there is only a small amount of debris present, you may want to vacuum it up using your own pool vacuum system.
