I just wanted to let the new guys know that adding a little DE to your sand filter works wonders.
A good friend of mine is in the process of purchasing a house and I was elected to fill the pool and get it up and running. I did that and I couldn't believe water could be so clear. His pool was completely empty with about 2 inches of dirt and leaves on the bottom.
Anyway, I cleaned and scrubbed the bottom before filling and once filled I got the chemicals in check but I was amazed at how clear it was. My pool has never been that sparkling, crystal clear so I added about 4 cups of DE into the skimmer and literally within 2 hours, my pool was visibly clearer and 4 hours later, my pool was absolutely crystal clear. I had to backwash 3 times and add new DE since yesterday but I couldn't be happier.
Just wanted to say thank to all you guys. You've been a great help.
