So I know that polyethylene plastic is commonly used for water storage and other aquatic applications but does anyone know if polypropelene plastic containers are safe. The reason I am wanting to know is because I am creating a fry tower and was hoping to use these polypropelene containers that I have found.

food safe is fish safe - allways. what you have to watch out for is inclusion of plasticizers (softeners - garden hoses), mold inhibitors (fairly commonly from arsenic), and release agents (non-natural - petroleum based.) with all three though you will find that with sufficient time to leech out the chemicals that can be made safe.
Well I did call the company that makes them and all they could tell me was thatthey were not food grade. I think what I will do is buy a couple and put some of my culls in them. If after a couple weeks everything is ok then I should be good to go to set them up for fry. Just to be safe Mike when you say leech them out should I just put them in a large container of water for a little while? Should I add anything to the water to help speed up the leeching process?

I think my LFS keeps the live rock in those types of bins. I would not put fish in those bins unless you put some vinyl liner in it I know vinyl is safe for fish because I use it in my saltwater tank.

Hmmm, well on the containers they said polypropelene. I wonder if polpropelene is different than polypropylene. The reason I am wanting to use these instead of aquariums is because 2.5gal aquariums are almost $10.00 versus $2.00 for these. Maybe my best bet would be too just buy glass and build my own tanks. Decisions, decisions.

maybe just swap the water a few times maybe over a few weeks, but it would need to be totally submerged. if you have culls you are willing to try out, it seems to be a quicker solution.
