[Aquaria]

ok well i dropped my tank off fri to have custom bracing done, he told me ready on sun. so i leveled my tank, put sand in, filled halfway, put rocks, then filled the last bit. got all equipment set up and on and the brace broke.....so my g/f thought she heared cracking its tempured glass was it cracking or trim moving idk but its half empty now, water just above the rocks with my canister and P.H going for flow. the adhisive (clear) was still sticky am i a fool i thought 48 hours was plenty foir it to dry, he neevr said anything to me?? or was i lied to and the tank finished today??
now what do i do can i clean it all up put brace back and fix it while its half full?? dont want my live rock to die.
