I've had a few bad experiences with plastic tub and buckets. If their new
they may still have some of the mold release agent on them (often look and
feels oily) wash all new plastic well. Twice I've put newly collected fish
in some 3 ft. dia 18 inch deep tubs until I could find a place for them and
had them die over night. If you us them out side most plastics degrade in
sunlight (UV) and outgases nasty stuff. PVC doesn't degrade but outgases
cancer causing substances. Polycarbonate holds up well in UV but it is not
flexible and storage tubs aren't made form it. In the plastics used in cars
most are painted the same color as the plastic to protect from UV. Be
careful don't put fish that are valuable in them first.
