Experiment #1-Capping gravel substrate with blacksand (sand blasting sand)
A controversial sand for aquariums, I have read some have had success without any problems. I have bottom dwelling fish so I am watching them and blogging them daily.
The water quality is much better than before and I am pleased with the looks of it myself.
