Hey, glad I could help. Don't fret over the lack of responses, posts get lost around here pretty easily... and I know I have a bad habit of generally only checking new posts in any given day. Sand seems to be a pretty popular method, but remember to be careful about overwatering, too. Standing water is where the gnats breed, so you want to be sure to eliminate that to the best of your ability.

Take care. :jointsmile:
