lotofish Posted February 7, 2013 Report Share Posted February 7, 2013 I am planning my first reef aquarium and have decided to not have a bare bottom tank. I therefore need some sand. I have easy access to marble chips and want know if it is suitable and the pros and cons of using it. Cheers Quote Link to comment Share on other sites More sharing options...
spoon Posted February 8, 2013 Report Share Posted February 8, 2013 Chemically it won't hurt as its mainly calcium carbonate and calcium magnesium carbonate, it will help buffer the water too. However I would be concerned about the size of the chips and your livestock. Marble chips tend to have sharp edges and would be unsuitable for certain types of fish that move or sift the substrate, also your substrate will become the home of many creatures the one that comes to mind most is spionid worms these need a fine substrate to build their tubes Quote Link to comment Share on other sites More sharing options...
