i am finally getting some where.i added some clarifier to the pool last nite and this morning the pool was crystal clear with all the crap on the bottom of the pool.i have vacuumed to waste 2times but there is still some stuff in there.i had planned to run the filter all nite but its going to ran alot this weekend so i turned it off.if it is not raining in the morning i will vacumm to waste again.i also tested the water for chlorine and had hardly any in there should i add some now or wait till im done vacuuming. phil
