sand?

Your primary digging concerns will be some of the cichlids--which I know little about, so won't comment. Other digging fish, such as kuhli loaches and eels, will love the sand, but won't cause a problem.

Instead of rinsing and rinsing and rinsing, put the sand in dry, straight from the bag. Put a plate in the tank and pour the water onto the plate so that it overflows the plate and wets the sand without splashing. I did this on both of my tanks, with medium grain play sand, and haven't had any problems with clouding. Never rinsed any of it. I planted immediately after filling the tanks, and it didn't cloud then either. I don't know if I got dust free sand somehow, or if this really works, but it certainly has worked for me--this is how we put the sand in the SW system as well (and that was about 150 lbs of sand!)
 
I tried a method similar to what OG is suggesting, and it didn't work at all for me. I had suspended dust, sand that wanted to float, air bubbles from nowhere for weeks, and a filter with a burned-out motor from getting sand particles in the impeller.

I may have just had overly-dusty sand, but I won't be going that route again. Love the sand though! Definitely a nice look in the tank.
 
I was thinking about getting some black/onyx sand to put in my 10gal tank....mix it in with my flourite to darken it up some...I think it would look much better with my neons and glow-lites...I also have some red shale rockwork in there, and think it would look nice with the darker, black substrate.
 
I got some dark sand (by 'eck it's expensive over here - 2.15 per bag, each bag about 3lb I think). But I was able to cut it 50/50 with silver sand and still had a good dark mix. A little darkness seems to go a long way.
 
Faramir, i get my sand from Animal House, which i dont think is too far from you, and if it is then never fear, they are the UK's largest aquatic mail order company.

i buy it from there at £8.99 for 12.5KG, or £10.99 for 25KG...i dunno maybe that is where you get it from, but i buy it bulk from there through their mail order, which makes it turn out cheaper.

i personally prefer the light colouration of just the silver sand, but i guess certain lightnesses and darknesses look best in certain contexts.
