In planning for my new tank, I have not decided on what to get for my substrate... What is your opinion????

Crushed coral tends to trap detritus and you would have to scratch any sand bed sleeping wrasses off your wish list.
Best to decide first what creatures you want to keep in your tank and design the tank around their needs..it's more homey that way![]()

personally I've had all, but agree with a few of you on creature choice. nothing beats a nice wrasse. At present shallow sand bed.
As was already said, they are all viable options that work well with the exception of crushed coral. It's just a matter of how you set them up and maintain them. In the proper hands they can all be effective but for ease of maintenance while still being able to keep most livestock happy I would opt for a "shallow" bed. So it's clear a DSB is considered to start at 4-6" and anything under that is considered shallow. I normally go with about 2" since that will keep most burrowing fish happy and leave you with an easily managed bed you can keep clean. If you want the benefits of a DSB I usually remote them to a large refugium where they can also be managed and the refugium inhabitants help keep it clean and the top layers turned over. If you are going with a DSB you want to use an oolitic sand so the water can move through it easily and you can actually benefit from it rather than have it compact over time and clog with detritus which would spell failure.
The other reason I like to use a shallow bed in the display and a DSB in the refugium is because I like to feed the fish and corals a lot. The shallow bed is easy to keep clean with a siphon and the high flow in the tank. Keeping the DSB remote from the display keeps that extra detritus created by large feedings from settling in the DSB and creating nutrient issues making it easier to maintain. More of the natural benefits without all the issues.
