So the 1500 gallon tank has been removed and here are the pictures as well as thoughts on its design flaws.
First, There were signs of water issues around to upper edges where water being splashed was dripping down behind the pond armor. To resolve this I would suggest waterproofing the upper walls as well as making them drip back into the tank (Like I did with the fiberglass panels in the new 2700). This will prevent any splashes from causing rot and mold issues behind the walls.
Second, there was an obvious leak on the area where the ID cat was able to put a divot into the cement board causing a pretty serious leak. To combat this the only thing you could do is to not use the concrete board, or install some kind of 3d foam background to absorb the impact of fish like these.
Lastly, I saw no signs of any structural issues or major design flaws other than the ones mentioned above.
I will also state that I am now a firm believe that all plywood tanks should be using some sort of fiberglass based reinforcements in all the corners and seams of the tank to add that extra level of strength and durability.
