Always run the pump when shocking the pool and allow it to circulate for 24 hours. The water should then be a blue or cloudy blue color. Shocking alone does not clear up a green or cloudy pool. This is what a filter is for. If the pool is filtered properly, you won't need a clarifier solution.
1 When the filter pressure rises 8-10 PSI over the clean starting pressure, it is time to backwash or clean the filter.  If there is algae in the pool, it maybe clogging the filter, keeping the pressure high. The filter cannot kill algae.
