Plastic Question

JustinReef · 10/29/2007, 03:40 PM

I have some HDPE rubbermaids I am using for a sump/refugium but I would like to change one to a bigger container and clear. I keep finding perfect dimensions but they are PP instead of HDPE, is this safe?

I did a bit of research and found that PP is used for food packing, so I thought it might be ok but Im really not sure.

Thanks

Looks like PP is used quite a bit for food such as yogurt and meats, so Im guessing it will be fine. Still would like to hear it from someone who has used it for a tank or knows for sure though!

PP (polypro) is just fine, no worries at all
