    Default Can you crush crushed coral down to make smaller sand?

    0 Not allowed!
    I just got a tank that was half sugar fine sand/ half crushed coral all mixed together and I didn't like it so I took filtered out the crush coral which totaled half of a five gallon bucket. I don't like how the sugar fine sand which is like dust is getting all over everything so I want to do a fine sand but not that small. Everything at the lfs seems to be a mix of fine sand or cc.

    Anyone have any experience crushing the coral down to small granules?

    If I get a sand sifting fish, will this be a problem? Thanks for your help.

    I have never tried to crush coral so I don't know about doing it yourself. I have seen crushed coral come in different sizes tho. The smallest that I know of is 2 to 5mm in size. Example in the below link

    Is that they size that you had in your tank ?
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    I have a mix of crushed coral and fine sand. My rather large pink spot goby doesnt have a problem sifting through it but smaller sifters would. If you want small sifters you need to have the correct sand for them whether you like it or not.It would crush fairly easy,you could use two cinder blocks to do it,time consuming but it would give you an appreciation of what it would have been like to make your own bread from scratch!

    The crushed gravel is about that size and bigger. It had alot of big,medium, and small shells of all dif shapes.

    I was using a strainer last night sifting it all out leaving behind the small sand/dust so I'm not apposed to doing the work. plus I have half of a five gallon bucket full of it. I was thinking about making something that can sift out most of the bigger pieces and crushing the rest a little at a time to get it to small granules.

    I even thought about using an old blender I had with some water and seeing if that works :) I can post pics of what I am working with. give me a minute

    I tried to crush it will a lil brick I had and while it works its not effecient. I found a blender in my basement and figured Id try that with some water in it and that didn't work. I may seek out ways to find and purchase the small sand I am looking for. or may come up with a more effecient way to do it....
