We just bought a house that came with an in ground pool. The only experience I have with pools is testing the water. When we moved in the pool was crystal clear, then we had a windy day and a day of rain and the water has slowly turned green. This morning I noticed the pressure in the filter was 10lbs. over the starting pressure from when we moved in so I backwashed the filter about 20 times until it ran clear. I also vaccumed all the debris to waste from the bottom and brushed all the dirt to the deep end. When I went to add my DE I tried to use a 5 gallon bucket but couldn't get enough water in to mix the amount of DE. I tried pouring it into the skimmer then adding more water and pouring, ect. Well then we got NO pressure and when we pulled the pump basket it was FULL of DE. I think I may have over measured the recharge amount (I was putting in the whole 12 cups) so I didn't tsress to much on the stuff caught in the basket.
Now I have the main drain on and the skimmers at minimum while I replace the pool water. I haven't tested the water today because of all the junk we stirred up, on Monday my pH was low but my chlorine was in the right range. I figured I would let the pump run until tomorrow morning when I get home from work and then test? Am I doing this all right?
