For showing me how much more enjoyable a pool can be when you don't have to fight algae. Even though it's "only" an Intex ultra-frame, your expertise allowed me to save money and enjoy my pool more. I did not have any algae whatsoever this year, and taking down the pool was so much easier when it had clear water! (Even after sitting a whole month without use!) I will definitely be becoming a TFP supporter soon!
