New pool owner here (of an old pool). I took the wedding cake steps out of my pool for the winter, pretty sure its the first time they have been removed!! Lots of debris/leaves underneath. There was 4 bags of sand totally greened up but still in one piece (barely) holding the steps down. There was one step pad that was duct taped to the back of the stairs between the wall and the stairs. When I put the stairs back in, do I need the pad on the back of the stairs or the bottom? Or both? Also is there any downfalls to cutting the pad to fit and gluing it to the back/bottom of the stairs?
