Hi guys, I just want to thank you all for such a great forum, I have installed a 7,700 gallon Bestway vinyl pool and am currently using the BBB method as described here, using solubor DOT as I am a farmer and have heaps of it on hand. I also have an SWG that is 2nd hand off a big inground pool allowing me to run it at around 20% for my small pool. All in all thanks to the info in this forum everything seems to be working well!
