Thanks to you both. Sorry about the various threads, but because i didn't have search rights i was unable to find my own posts. Sorry, almost panicking here -- actually debating whether to return pool as it's not out of box yet. Yes talked to sand company, they're charging $340 for two cubic yards of sand.
One of my questions is answered, in that you are suggesting that the salt water system is not a good idea, that i should use this bleach mix. Correct? Is there a bleach odour?
Also, i have still not gotten an answer to a HUGE question -- if i build an 11x20 base around my 9x18 pool, is it wide enough, or with support stands do i have to go wider?
