Lol and sponge filters are useless with rays and their bio load. Plus one 18" ray can create as much if not more bio than the fish u got rid of. And if I were u I would take the gars out! Too many stories read that gars take a bite out of a ray
Dude! Ur beneficial bacteria will start dieing off after 1hr of the power being off. So 24hrs without ur sump running killed ur BB! It could very well be ammonia burn.
