I currently own the EDSAL particle board muscle racks that hold 800 lbs per shelf. However I noticed that the board inevitably bends slightly causing the aquariums be a not so level. Is there any recommendations for aquarium racks/shelving I can find in the US? I have a 20 gallon long, 3gal nano, 10 gallon, and 2 5 gallons. I need something that's just more sturdy and won't bend when weight is on it.
