My pool went up Saturday and the fire department finished filling it Sunday night. That night I added 3 bags of shock to the green water. Yesterday morning the pool was green and there was rust all over the ladder. I added algacide in the morning and then Metal Out last night. This morning I can see the bottom but it's still green. I will test the water tonight, but I'm not sure if I should add something to it now or just let it filter throughout the day and see if the green will go away.
