on the structure i drilled tons of holes to prevent anaerobic areas (i believe its called anaerobic, correct me if i'm wrong) anyways i used these holes to attach the rock with zip ties. it work awesome, i secured almost every rock with 2 zip ties to prevent them from turning. intially i tried using epoxy but it didnt work to well. i designed the structure to come apart in sections. i would take a section out sit it on the ground and would attach rock to it. way easier than doing it in the tank. i then reassembled everything in the tank.
