Thanks again Byron, I thought I had read that swords liked 3-4". but if 2" will work, that's good for me and costs less too, especially since the acrylic tank has no rims to block the substrate view. I know I have anaerobic spots in my 10 gallon since I'll pull plants and get the bubbles, along with some really stinking buried plant parts sometimes...
On the flip side, I have noticed no problems with the plants, snails, my young plecos, or other fishes in the tank. Your advice is good - if it's not really an issue, don't make it one!
