The most transparent material to most wavelengths of light and UV is quartz. You can get quartz glass for not much more that regular glass. POlycarbonate and acrylic absorb UV and can begin to yellow with time. However, I must echo the comments above about covering your tank. If you are loosing water like crazy it would be WAAAAAAAAY cheap building yourself an ATO. You could build one for about $20 to $100 depending on how resourceful and crafty you are.
