I'm having a hard time decided what to use on top of the soil as a gravel. Should I use black blasting sand? I really love how it looks. Is there anything thats suggested?
I used Tahitian Moon Sand from Caribsea in my 55 and I really like it. It's fairly cheap, jet black, and a nice mix of sizes. It won't compact like true sand, but it's not as clunky looking as basic gravel.
Here's a picture of it submerged. The color came out a bit yellow, but you get the idea. Looks 'natural,' though I've never seen anything like it in nature The brown flecks are MTS snails, which are sold separately.
I was at the LFS today looking at all the gravels and sands. The only one that caught my eye was $20/bag. I said no thanks Im thinking I'll simply get some Oil Dri from walmart..
If you want a dark color, try Safe-T-Sorb from Tractor Supply. It is similar to Oil Dri, but much darker in color and reportedly less dusty and easier to wash.
