Stand is plenty heavy - just trying to weight the actual metal lighting stands down, as they're seated atop shelves. Have baskets on top of the stand platforms holding them down.
Going as low-tech as possible since this is a shrimp-only tank with the addition of some Otos. Lots of open space for shrimp observation. Not gonna do much with carpeting plants since Otos tend to be sneaky little buggers that stir up substrates on occasion. You should see how they're behaving in their current holding tank that's got a sand bottom.
