Well, Edd, The same dilemma is addressed by woodworkers trying to make 
bookshelves that hold the weight of 40 years of Tropical Fish Hobbyist magazines -- 
probably as heavy as tanks of water. The latest word is that plywood is better 
than anything else but the key is the length of the span. I have inserted 
upright supports every 16 inches in my bookshelves and you could do the same in 
your fish tanks racks. Half inch plywood as a vertical divider is strong enough 
in compression, but not in flexural rigidity.
