I was about to start another thread, but this is just the place to say how much I love this forum. I' been treating water in an industrial setting for almost thirteen years but have learned so much here. Some has even been a good refresher for my job skills, and actually been fun. I go to pool school often and learn something new just about every time. The amount of knowledge here is impressive to say the least. I dont have a real pool, but I get into keeping it nice and watching my chemistry as much as anyone. If I can ever talk the wife into it, I'll have a respectable IG or AG pool someday in the near future. I've used tabs and bleach until finding TFP summer of 09'. Thats when I started using Borax and lovin it. Not trying to brag, but I've been quite successfull too. Been lurking again this season and really getting more interested in tweaking and learning further. I haven't found a place I like better and just wanted to say it. Thanks to all of you here.
