Sloping with blasting sand?
I just got into planted tanks about 6 months ago (and this place has been a huge help!). I used medium grit blasting sand on my 120, and I've noticed it doesn't maintain the slopes I created very well - i guess the word "settles" might describe it. I didn't have anything steep, but probably went from 2" in front to 4" in back on a 18" wide (front to back) tank. There's a little slope left, but not near as much.
I made a deal on a used 240 yesterday, and I'm wondering if I should use the coarse grit instead of the medium when I set this one up. Suggestions?
