Building 27' 52" round pool and dont have enough sand Instructions called for 2" sand which I have with 1' paver under each post flush with top of ground. I missed the part of burying the paver so now pool wall and track up bolted 1" too high leaving only 1'of compacted sand in pool. To add now would have to dump outside and shovel in(too much work). Two questions with cove can I leave as is and will j-hook liner stretch that extra inch??? Thank you
