Hi Sunny;

Unfortunately, it's typical for pool store advice to be less than helpful.

But, you have not told us enough for us to be able to help. Do this:

#1 - Tell us what the problem is. Is the water green and cloudy?

#2 - Turn your pump on, and leave it on all the time, till the problem is fixed.

#3 - Get your water tested (or test it) and tell us the readings. At a minimum, we need to know chlorine, pH, and stabilizer levels.

#4 - Tell us what chemicals you've added during the last week.
