There are hundreds if not thousands of compounded plastics used today. The plastic itself wont harm your fish, its to additives that are compounded into it. Things like glass fibers, mineral, flame retardants, colorants, release, silicone, formaldehyde(my personal favorite)...and the list goes on. I worked in the industry for 25 yrs and my lungs are trashed from the gases released during processing.
Styrene which is what is used a lot for filters and other aquarium components is highly toxic. Its ok until its heated and it will release gases. Ever notice that "new car smell"? and "New carpet smell"? That is styrene gases still being released and will for upwards of 3 months after processing.Styrene gas is deadly.
Polypropylene and polyethylene is safe.
PVC airline tubing is safe as long as its not heated, if it is its deadly. PVC is nasty stuff and the gases eat steel faster than saltwater.
As Byron stated, use aquarium products only if your not sure. And if you open the box and it smells like fresh plastic...its releasing gasses.
