I have been using the information on this amazing site for about 2 years to educate myself and manage my own pool/hot tub water. I have successfully extracted myself from the frequent and expensive trips to the pool store for water testing, chemicals and advise. When people ask me who manages our pool, I proudly say me. You are 100% correct...a pool is like a pet, needs a little attention every day. Thank you for making my life easier and fun (surprisingly I find it enjoyable to test my own water and tweak the chemicals a little at a time).
