Very cloudy....it has been 3 weeks now and it is just a hazy grey color. Our polaris was in the shop 2 weeks ago, so, I took a water sample to have it tested. Their test showed everything was ok except it was scaling. I have just been keeping the chlorine level high and keeping the other numbers in range. We have two sets of filters, so, we have changed those as well. I didn't realize it could take this long.
