Hello, I'm 3 years into pool ownership. Struggled the first two years from never having a pool, and obviously not knowing a darn thing about it. Then I stumbled across Trouble Free Pool, and I have to say that I can't thank everyone enough for their wisdom. All the posts I've read trying to self educate are extremely informative, and they explain things very plainly. Best advice.....buy a really good test kit!!!!!! I have never felt so in control of the pool as I do now, because of that test kit. I've had one bout with algae this season (before buying test kit) and with all your advice was able to clear it in 4 days. Thanks a million.
