hey i have Crushed Coral substrate in my 30 gal tank and i am currently a month into my cycle. When i purchased the tank it came with the crushed coral already in the tank and soaking in SW. After reading all the posts on here i realize i want a sand bed now since it is better for all the sifters in the tank is there anyway i can put the sand down on top of my crushed coral or do i have to remove everything and start over again?
