I've had a tank set up for about a year now and the substrate is currently sand. My question is, I don't like the sand anymore and want to replace it all with crushed coral/ coral gravel. Can I remove all the sand and then put the coral gravel straight it or would this have a negative effect on the aquarium ie causing a cycle again? The reason I don't like the sand is the water never looks completely clear and there are fish and shrimps that disturb it and send it into the water column. I have heard about seeding the new crushed coral but how would like work?
Thanks.
Thanks.
