The old greenish has arsenic and copper in it. that equal dead fish very quick.
I dont know what the new yellowish has in it but its supposed to be more ecologically sound. all i know is its a rip off. they decided to use a substitue that rusts regular steel nails in 3 months or less. you have to but special screws at 4x the cost(or so the box says)..blahhh
not to mention its overkill. if your stand is going to be wet enough for long enough to rot, you have bigger problems.
