stick toward the surface and stay near the aurora, and the reapers there shouldn't bother you. stay away from the back end, by the engines (nothing really useful there and that's reaper territory). I have not made it to the grand reef either, but keep your volume high, bring extra batteries and foodstuffs, and you should survive. if you enter any cave systems, drop a beacon at the entrance.

hope i helped you! good luck!
