i'm sure any size would be good, except any grade that resembles your standard aquarium rocks because it could get ingested and impact you poly. How much is sand is the by the way in lbs?
I found this sand at my local tractor supply for under $30, i know many of you are recommending garnet sand and so i was just wondering if this was the same thing since its designed for sandblasting? Also if it is would 80 grit be a good size?View attachment 834861
I check this out today, my verdict, im not going to use it. The reason why is it is to "fine" for me. It is finer that sugar almost a powder. so out of town i got to get a larger grade![]()
