spedwards Posted February 28, 2006 Share Posted February 28, 2006 I will be setting up a new Malawi display tank in the near future and have decided to use crushed marble for the substrate. What size do people normally use? I can't decide between "pool dust" or 00... I have used 00 before and found it to be a good size, but the pool dust being a closer match to sand is something that interests me. Also, do you lose much (or any) of the pool dust size when doing a gravel vac? TIA Cheers Jon Link to comment Share on other sites More sharing options...
Sarah Posted February 28, 2006 Share Posted February 28, 2006 i use both and the really fine stuff tends to get sucked up when you do a gravel clean , but offcourse looks sensational there are two different shades available i have the really white marble dust, i also have the 3mm size which is more practical cheers Sarah Link to comment Share on other sites More sharing options...
Stuart74 Posted February 28, 2006 Share Posted February 28, 2006 I have over 120kg's of the 000 size in an 8ft tank and find it to be excellent Do I lose any Well a little bit, you just have to be careful when you gravel clean With using the marble you don't need to suck the substrate halfway up the vac as you will find most of the fish waste will sit on top Link to comment Share on other sites More sharing options...

chrisso81 Posted March 1, 2006 Share Posted March 1, 2006 Here ya go dude: Stu's monster! I regularly visit this tank and it looks awesome! Link to comment Share on other sites More sharing options...
spedwards Posted March 1, 2006 Author Share Posted March 1, 2006 It is a great tank. Pool dust looks good, but I'm not too keen of having piles of marble forming on my lawn during water changes - I think 00 is the G-O! Thanks all! Link to comment Share on other sites More sharing options...
CThompson Posted March 2, 2006 Share Posted March 2, 2006 Limestone will be better than marble. For a limestone substate call Phil Fairall at Limestone Quarries Australia on (02) 9544-7939 or mobile 0419 -047777. $2.00 per Kg or $1.50 per kg for 200 kg Haven't spoken to him in a while, I assume he is still doing it. He can crush limestone to size requested, from like 1-2mm to 10 +mm. Craig Link to comment Share on other sites More sharing options...
