What types of plastics are not reefsafe?

The material used to make it is HDPE ( high densisty PolyEthelene) I
have found the website for the manufacturer in England and have sent
them an email asking for information. I'll have to wait to find out
what they say. Their website says they make plastic water storage
cisterns as well. Hopefully all will be well. I will wait for a
response before I try to use it.
Thanks Toni for the reefcentral thread. That puts my mind more at ease.

I was given a 50gal plastic rain barrel made by Lee Valley Tools as a
christmas gift. I am hoping to use it to set up a float valve to
store R/O or mix up SW for water changes. Are there any types of
plastics that are not safe to use for this purpose? This dark green
plastic barrel is brand new and never been used. Has anyone ever
had a problem using a plastic container? Anyone have any ideas? I
was planning to thoroughly rinse it out and then fill it, let it soak
for a few days and then dump the water. If anything were going to
leach out of it would this help to avoid any problems?

Thanks,
