It may look as if this thread is in the wrong Forum, but in time you'll understand. I need to ask a question (or more) for the guys who knows something about Graphite. 1.) Will Graphite perish if submerged under water? 2.) Can Graphite be underwater for long periods of time? 3.)Where can I buy Graphite sheets or pieces (about 400mm x 400mm)? 4.)Is there different sheet thickness available, eg 5mm etc? 5.)Will Graphite give off a chemical of some sort, influencing the water parameters??
