hey all. i need some advice. i have been removing my crush coral a little at a time with each water change, but i need to get it all out alot quicker so i can get a sand bed in it. am i gonna mess anything up if i was to take everything out and put it in a big container, remove the rest of the cc and replace it with sand then put it all back in? will i cycle again? i am thingking of vacuuming it all out into a filter sock or 4 and pouring the water back in...what is the best way to do this?
