    New Substrate: Sand or Crushed Coral?

    I'm in the process of establishing my new reef tank & wondered what your prefer as a substrate & why? Assume that cost is not an issue.

    Hey Gump!!! I have two tanks now with crushed coral and it's o.k. I am also in the process of setting up a new tank and I will be using Aregonite for the new one. Personally I like the sand beter cause it's cleaner looking. JMO though.

    Why is it called "cargo" when it goes by ship, and "shipment" when it goes by car?

    For what it is worth, I am actually thinking about bare-bottom for my next tank. My other choice would be sand.

    Since I dont believe in DSB,I Use just enough Araganite to cover the bottom for esthetics only and its a mixture of different sizes.
    Araganite is available in a whole lot of sizes fromm oolithic to rubble.

    I was originally going to go with an Aragonite sand bed, but decided to go with Aragonite and add some crushed coral for extra buffering abilities. I made a mixture of roughly 65%Aragonite / 35% Crushed coral...IMO the sand bed is still very nice compared to a crushed coral sandbed only, it looks like an aragonite bed with some bits and pieces of CC.

    Thanks for the replys. I was really hopeing to get into a discussion about particle size,buffering capabilities & holding capacity for aerobic & anerobic bacteria??

    I am a firm believer that the substrate should be "graded" meaning all particals of the same size. It will pack down far less this way.

    I have sugar sand in mine. And if I could go back and do it over again I would put some smaller aragonite. I have a gobie that is constantly throwing it up in the water coloum, and it gets all over my corals and makes the water cloudy.

    same thing as gools, i think its look nicer (sugarsand ) but its too easy to get everywhere. A mix of sand size should be good! Also sugar sand is bad when you want flow in the bottom.
