I just would like to say that I have learned a lot from this site. I bought a house in January and with it came a 33k IG swamp. I have never had a pool, but I have turned the swamp into an almost clear pool thanks to all of you here. I still have yet to pass an over night test. My pump died today. I will be getting a new one installed on Monday and with the cooler temps here in NH, hope to not lose any of my progress so far. I appreciate all of your time and dedication to keeping this site such a valuable tool to pool owners like me.
