This is the best inexpensive tub that will fit my 6 x 2 foot costco racks 36 x 24 x 8 inches 23 gallons. The local hardware stores sells them for $14. They are heavy duty HDPE or similar plastic and are much stronger than the pvc tubs sold for a similar price at Home depot. The are stocked at ACE hardware stores. The ridges add to their strength but unfortunately the ridges in the bottom interfere with my preferred bulkhead placement but I can work around that.
