Hey guys, I am from the Chesapeake, VA area. I have an 18ft Above ground Pool with a Sand filter. I have had a pool for about 7 years and have exclusively used the Pool Shops to handle testing and buying my chemicals. I always spend an arm and a leg every year and it seems that my pool never gets to the point I would like. I ran across this forum doing a search for pool parts and started reading the post and have realized that it is very likely that my Pool store, (I use 3 different places to test my water because I have never trusted just 1), has been jerking me around to sell their chemicals. I am ordering my test kit this week and can't wait to get started with the BBB method. Right now my pool is semi-cloudy, I can see the bottom but only if I look straight down.there are a lot of particles floating in the pool. Added Ultra-Brite to try to get the particles to filter better. losing a lot of chlorine daily. I will post pictures this afternoon when I get home.
