I can never get enough of looking at those pictures! I can gratefully say that I have never had my pool turn green in the spring at open (knock on wood!) but it was really cloudy once with some green on the sides when I entrusted lazy teenagers to maintain the pool while DH and I went away for 4 days - I freaked out for 1 min, then regained my wits and started dumping bleach and brushing - a few hours later it was back to sparkling clear.

That set of pictures should be in some type of sticky or slide show as a "truth in advertising" ad for BBB.
