Ive built a few stands like this and didn't have as much support as the other, I used 10 supports and normally I only put 4 legs.... It will be perfectly fine
I think it'll be fine as it is.
If you have you would want lateral support![]()
lol did one of your drunk friends knock over your tank before?
True...because plywood acts as a "shearwall" in this case. It's how well-made houses in California resist lateral stress from earthquakes.If it wasn't sheeted with plywood I'm certain it would have been on the ground.
