sharronpaul Posted July 1, 2007 Report Share Posted July 1, 2007 Hi all, HAs anyone here ever used garnet (orange-red-pink sand) as a substrate in their freshwater tank? The reason I ask is we're sandblasting the floors of our Premium Unleaded tank at work (6.4 million litres) and the sandblasters have kindly offered to donate me a couple of bags of garnet. I thought it'd look cool in a cube with some central stones, and maybe some convicts to act as acontrast. Whats everybody's thoughts?

Loopy Posted July 1, 2007 Report Share Posted July 1, 2007 I don't know anything about the scientifics of the idea but as long as it is clean and pure i don't see why not. Perhapes as an experiment soak a handfull in a tank and monitor the hardness and pH levels (and any other elements of importance) to see if they are affected by the garnet. Otherwise i would just say you HAVE to post pics once you set it up!! Quote Link to comment Share on other sites More sharing options...
Alan Posted July 1, 2007 Report Share Posted July 1, 2007 set up a small tank and put some disposables into it. Quote Link to comment Share on other sites More sharing options...
smidey Posted July 1, 2007 Report Share Posted July 1, 2007 i used to do sandblasting which we often used garnet for finer abrasive blasting. be careful it isnt to fine so it doesnt end up being stirred up by the water flow. Quote Link to comment Share on other sites More sharing options...
Caryl Posted July 1, 2007 Report Share Posted July 1, 2007 Is it rough or sharp? It may damage cory or other bottom dwelling fish's mouths. Quote Link to comment Share on other sites More sharing options...
sharronpaul Posted July 1, 2007 Author Report Share Posted July 1, 2007 It's like sand, just red. Looks cool when dry, as yet haven't wet any to see what it looks like underwater. Might grab some off them tomorrow and see what it looks like Quote Link to comment Share on other sites More sharing options...
smidey Posted July 1, 2007 Report Share Posted July 1, 2007 Is it rough or sharp? It may damage cory or other bottom dwelling fish's mouths. its very fine, the bags we got were much finer than sand. it was used instead of shot which is very rough to blast paint off & leave a smooth paintable surface on the steel.

sharronpaul Posted July 1, 2007 Author Report Share Posted July 1, 2007 The grade they're using is "80", which I think works out to 80 microns? If and when I get it all sorted (and if it works!) I'll post a photo. Quote Link to comment Share on other sites More sharing options...

I'll post a photo. its been a while since i had anything to do with garnet & microns but isnt 80 microns 0.08 of a mm? if so that is very fine & will be washed around at the blink of a fish's eyelid Quote Link to comment Share on other sites More sharing options...
sharronpaul Posted July 1, 2007 Author Report Share Posted July 1, 2007 Yep, I guess 80 microns is .08mm......... will try it in a glass tomorrow and see what happens. Quote Link to comment Share on other sites More sharing options...
