  • Tank is really durable
The preset inlets and threads are amazing. No need to drill any extra holes. The triangular grooves in the sides help for stabilizing the tank which is a plus.

Fits the job I needed it for, at a fraction of the cost. Only made slight modification at almost no cost.

  • Do not purchase! Leaks
3 of the glue welds around the fittings leaked. I ended up repairing it with a plastic welder because shipping was so expensive to return it, and pay again on a new one. Do not buy from this company apparently they do not check for leaks prior to shipping.
