Hi everyone, since I can't find any black sand I thought ill just DIY my own.
It pretty easy to do all u need is some safe spray paint.
Step 1. Wash ur pfs. Make sure the water is clear
Step 2. Lay the pfs out, let it dry out. Once the pfs is dry leave it lay.
Step 3. Use the color you want, spray it with the paint. dont be cheap use as much as u think it need. Let it dry mix it up all around, spray again, keep doing it till you think its done or till ur happy. Let dry ... throw it back into the bin or bucket, add water n wait.
Once u think everything is set ...drain the water out, add th sand to ur tank.
Pass this around to friends and share the idea.
I'll report any pro n con on.
Note: in the long run the paint might fade off so let it cure, the longer u cure it the longer it will last in water. Same thing as spraying you pvc
