Hello everyone, my name is Megan. I am a single mom to three beautiful children. We recently, one month ago today, moved into our first home, it is wonderful house in a great neighborhood with lots of kids. The backyard completely drew me to the house. There is a beautiful deck attached to the back of the house and a nice deep flat backyard, and WE HAVE A POOL!!!! It is an 18 foot round 4' deep above ground, with a hayward pump and a sand filter. I ordered my TF-100 test kit and received it 3 days ago. I came across this site because I have had some unfortunate troubles with the pool, which I will post under the correct thread. The knowledge and information I have gathered from this site is invaluable. I am looking forward to learning from you all as I continue to enjoy this new hobby.
