Previous at this tank

You don't start a project like this out of the bleu. You must do some research . That's why Mister X build a "small" tank to try different things. This is a 4200 gallon tank. This tank is filtered threw a very big biological filter build on the back end of the tank. By starting this tank he found out some things which can be prevented in the 26000 gallon tank. For instance that 20 foot of water looks green with a "normal" glass front. That's why in the mega tank the front glass will be of crystal glass of 1 inch.

The current "test"tank is filled with almost black sand, this absorbs a lot of light, which makes it almost impossible to take a normal picture of this tank. But I did take some pictures to show you what a wonderful collection of stingrays this man has brought together. You see only the front of the tank ( their was enough light ) and al the animals you see are about 20 inch some more, some less.
