Ducksta Posted May 22, 2004 Share Posted May 22, 2004 BEST: coral sand BEST VALUE: crushed marble shell grit looks kinda poxy IMO as a substrate on its own (at least the shellgrit I have used/seen) It is best used in filters, or moxed through sand or gravel for a very natural look.

Matthew Posted May 23, 2004 Share Posted May 23, 2004 G'day I reckon for looks go with coral, but ethically I reckon you shouldn't! Best is crushed marble. It looks quite good and does a good job with buffering. It also looks a lot better than shell grit. Shell grit seems a little sharp as well so I tend to not like cleaning filters that have it in there, also if on the aquarium floor it may injure the fish and/or their slime coating. It also tends to look a little dirty at times. Link to comment Share on other sites More sharing options...

Teamsherman Posted May 23, 2004 Share Posted May 23, 2004 If you ring up any gravel and/or sand supplier (should be heaps down your way) they will most likely sell 25kg bags for about $11. Hope this helps. Cheers, Alan. Link to comment Share on other sites More sharing options...
r.d.m Posted May 23, 2004 Share Posted May 23, 2004 if you get the fine grade of shellgrit it looks okay Link to comment Share on other sites More sharing options...
FREAQ Posted May 23, 2004 Share Posted May 23, 2004 Travolta Lots of Bubbles in Unanderra sells crushed marble in 25kg bags for $50 or $55. (I feel a bit expensive) I was told though it will only buffer to about 7.2 or 7.5 cant remeber which, can anyone who uses this clarify? Otherwise try M J Rowles or small loads etc (local lanscape suppliers) Link to comment Share on other sites More sharing options...
