henward Posted April 28, 2011 Author Report Share Posted April 28, 2011 same as the sand you get in urns for ashtrays are silica i think Quote Link to comment Share on other sites More sharing options...
Warren Posted April 28, 2011 Report Share Posted April 28, 2011 I'd expect Southland Sand and Gravel could supply it. Years ago I purchased about 1000kg of fine sand-like gravel for several tanks (one is the 8 foot tank you now have - about 500kg went into that). It cost only about $70 for 1000kg and $600 in freight to get it to Napier... Southland Sand and Gravel (Invercargill) have a very big range of graded sand and gravels - both size and colour graded. Maybe worth checking them out. Quote Link to comment Share on other sites More sharing options...
GZ_Loach Posted April 28, 2011 Report Share Posted April 28, 2011 There is some new fine sand on TradeMe called "Black Satin" its the size your talking about but it isn't pitch black, if your buying in bulk the dealer usually gives you a discount Quote Link to comment Share on other sites More sharing options...

BikBok Posted April 28, 2011 Report Share Posted April 28, 2011 petmart also sell the black satin sand, but I don't think it's silica http://www.petstuff101.co.nz/Product.aspx?ID=350 Quote Link to comment Share on other sites More sharing options...

Warren Posted April 28, 2011 Report Share Posted April 28, 2011 Watch out for Silica based sands - they can cause a lot of brown algae... Quote Link to comment Share on other sites More sharing options...
BikBok Posted April 28, 2011 Report Share Posted April 28, 2011 that's going to look awesome. Good luck Quote Link to comment Share on other sites More sharing options...
GZ_Loach Posted April 28, 2011 Report Share Posted April 28, 2011 I had black silica sand in my large tank and then ended up using a combination of black silica sand and fine grey sand, looks pretty good together because due to the strong flow of water in my tank the larger grain black silica sand gets seperated and sits in pockets by itself :digH: Quote Link to comment Share on other sites More sharing options...
henward Posted April 28, 2011 Author Report Share Posted April 28, 2011 yeah found that with silica sand too i like the natural-ness of it lol Quote Link to comment Share on other sites More sharing options...
Sophia Posted April 28, 2011 Report Share Posted April 28, 2011 The black satin 'sand' is extremely fine black grit gravel, grains the size of sand, but I believe it should be treated as gravel not sand. Still a great shade of dark though. Quote Link to comment Share on other sites More sharing options...

jim r Posted April 29, 2011 Report Share Posted April 29, 2011 Southland sand and gravel have white silica but not black silica sand. I believe their is a company in Dunedin called Blackhead Quarries who have it but I cannot confirm this. Tel: 03 4879031 Quote Link to comment Share on other sites More sharing options...

Sophia Posted April 30, 2011 Report Share Posted April 30, 2011 This is the place http://www.industrialsands.co.nz/products.html Not open on the weekend. The sand they call 'black silica sand' is the one called Iron Sand Concentrate and it is apparently black sand like west coast beach sand, as compared to the dark brown Woodhill sand which they also have. You can check the analysis of each one also. The Iron Sand concentrate has nearly 80% ferric oxide which I think is the black stuff, Woodhill has only 22%. from Wikipedia on ferric oxide "Aquariums Ferric oxide in a granular form (GFO, granular-ferric-oxide) is readily available for purchase in the saltwater aquarium and reef community. Its primary function as a filtration media is to pull phosphates out of the water column to aid in the control of nuisance algae. Branded products such as PhosBan, ROWAphos, and PhosLock contain proprietary blends of granular-ferric-oxide and granular-ferric-oxide-hydroxide (GFH)." From what I can read it looks like ferric oxide also binds other minerals etc. Does that mean it would stop the absorption of nutrients present in Flourish Excel for example?

hovmoller Posted April 30, 2011 Report Share Posted April 30, 2011 Yeah I think "Black silica sand" is a contradictory in itself.. I don't think silica itself is ever black? Just go to Muriwai and load up a couple of buckets of iron sand (what Sophia said). Quote Link to comment Share on other sites More sharing options...
Sophia Posted April 30, 2011 Report Share Posted April 30, 2011 yes the silica content as they call it in the breakdown is low in the concentrated version. Quote Link to comment Share on other sites More sharing options...
