We are about to vermiculite the bottom of our T shaped inground pool kit. We have read much about how to mix and ideal surface conditions. But we cannot seem to find any information on how to string the bottom (we have round corners) or any other tips for the actual installation for the do-it-yourselfer. Any advice would be greatly appreciated. (We tried to hire this out but the "contractor" keeps giving us one story after another about why he isn't up here doing it and we need it done ASAP). Thank you!
