So I got my K-2006 kit back in June when I discovered this place after dealing with algae. I was too cheap to buy the speedstir at the time, so a few weeks ago I decided to buy it. I am in love!!!! This little guy is so worth the money. My husband doesn't complain anymore that he now spends more time "dealing" with the pool. He was out of town and left me to deal with the algae when I found this site. By the time he got home "my" pool was sparkling and has been ever since. Before finding this site we used pucks and bags of shock. He loved the idea of only having to dip the strips in and doing his maintanence once a week. But we always fought algae at least twice a season. Now he says it's too much work. Really 5 mins a day!! I got the speedstir and he says this makes me happy and no longer complains about our daily morning routine. I can now tell by looking at my water if things aren't right on. I love the sparkle!!!! Now if it would just warm up enough to enjoy the water!
