Botanicare Reservoirs -- 20 Gallon Bottom

After receiving it I wanted to know just how good it really is, so I held it up to an LED light up at close range to see if any light could penetrate through the walls and I was pretty amazed that there were only a couple of spots where a very dim amount of light got through at all. So it really reinforced my confidence that I won't need to worry about light causing me other issues when its full of nutrient solution later on.

There is two small flat spots in the center of the tank front and back for drilling your bulkheads into place, I had to drill through both places on mine, and I was very happy that it was easy to drill them into place without any issues or problems. Even when the tank was full of water I did not see any bulging or changes in the tank to give me any concern, so I am really happy about that as well. Overall I haven't had a bad thing to complain about with this tank and its design has been everything I was really hoping and looking for in a reservoir.
