I just had my pool replastered and it was filled 5 days ago. The pump/filter has been running 24 hours a day and we have been brushing the pool 4 times a day. Today the water level was a little low, so I added some water with the hose, so it was back to the middle of the tile level. Now there is a HUGE light colored streak down the deep end, like the hose water did something to the plaster. The hose was not touching any of the pool, just laying off the diving board into the deep end. Has this done permanent damage/discoloration?!
