The Dungeon Of The Oblivion
I have to admit it: the best part of this tank is the peculiar shape! What you're watching, is the bottom part of the counter in my shop. My computer stands on it as I am writing these lines. Making this tank was a eye-blinded bet, because using 2 convex and 3 plain glass pieces to build a 180 x 190 X 60 cm. was actually a very difficult matter! One thousand litres of water that exert their pressure on the glass are always unpredictable, when the shape is not cubic! And, of course (as Murphy's law teaches) the first tank we built was a failure! Have you an idea how 1000 litres will look if you pour it on the floor? A LOT! We had to built it again and, finally, the tank was perfect.
Tank : cm. 180 X 190 X 60 in a "S" shape
Temperature : 28-30° C.
Lights: 2 fluorescnet tubes 60 watt each.
Mechanical parts: 1 biological filter (volume: 100 litres) plus 3 pumps 1200 lt/h each.
Animals: 1 superb Cyphotilapia frontosa (11 years old!), tons of Melanochromis auratus (in the beginning there were also Pseudothopheus, Julidochromis, Nimbochromis, Neolamprologus, but, because of the reproduction ability of the Melanochromis auratus (impossible to net the carrying female in such a big tank), I had to remove them.
Chemistry : KH=10, pH=8.2, NO2=0, NO3=0,5-15
Notes: This tank is right on the floor and the space over the top, to work inside, is only 17 cm, so it is impossible to siphon the gravel and build a more complicated landscape. But the rocks are very good-looking and give the feeling I was looking for, and African Cichlids are very clean fish, so I use just a pump for the changing of the water.
The light you see in the pictures, are 60-watt normal (tungsten) bulbs. I chose them because, in the beginning, I used 2 blue fluorescent tubes (see photo below) , but I was looking for a dramatic effect, to give the feeling of a "hell's cave". I liked this "dry" yellow light and the sharp shadows it creates, bouncing on the rocks a lot.
