Reef Chemistry Question of the Day [HASHTAG]#128[/HASHTAG]
Polyethylene is widely used by reef aquarists for many things. It is a good choice as it is nontoxic, resistant to most chemicals we use, and can withstand the temperatures we are interested in.
For example, I use it in the form of Brute trash cans for sumps, limewater storage, RO/DI storage, new salt water storage, and refugia.
What elements are needed to comprise more than 99% of the weight of polyethylene used in objects such as trash cans?
A. C, H and O
B. C, H and N
C. C, H, N, and O
