I haven't posted much in the forum but I have been reading it every day and applying the advice to the care of my own pool. Thanks to you guys I have sparkling blue water and we are ready to go swimming. Here are a couple of pics from before and after. Pay no attention to the apparent cloudiness of the long pool in the background. This picture was at a stage where the square pool was done slamming and the second was not quite but almost done. Thanks!!
