jointing sand substrate?
Hi guys, So today I was at my local home depot looking for pool filter sand. Unfortunately I didn't find any. Instead I grabbed a 80lbs QUIKRETE PATIO PAVER JOINTING SAND for 11 canadian dollars. Has anybody tried this stuff as substrate? I have an unsightly blue gravel on my planted 45gal bow but I don't want to uproot anything so i'm planning to cap it with this.
