so the dead coral will have bb after sometime also right?
so how many kg should i need for a 2feet?
so once i put in, is it that i must not disturb the sandbed anymore ? even after 1 or 2 years.. same method as planted tank?
but then i heard that, there will be no aeration in the sandbed and the bb will not grow in it. so normally people put a heater at the bottom .. hot air goes up cold air come down...
