Tank 4: 161 gal African tank

Picture of African tank

This is my fourth largest tank and has been devoted to large African fish
- several Polypterus species (bichirs), an African tigerfish, and a Synodontis catfish.

Tank Size (LxWxH) Approx 7x2x2' (84x23x24"/213x58x61cm)
Volume Nominal: 161 imp gallons/192 US gallons/725 litres
Actual: 136 imp gallons/162 US gallons/612 litres (+ 27 UK gal filter volume)
Filtration Home-made external filter box - 24 x 12 x 28" (61 x 30 x 71cm), powered by Hagen PRO4 powerhead with Quickfilter cartridge. There are triple pre-filtration sponges (course, medium, fine), and the main biomedia is highly porous Alfagrog rock. In addition, an Eheim 2010 internal filter is used for extra circulation. There is also a large airstone to help maintain a high oxygen level.
Heating Heated room
Lighting Low - fluorescent room lighting only.
Substrate Thin layer of aquarium sand
Decor Bogwood, large smooth rocks, large artificial plant
Background 3-D effect artificial background
Water parameters Temp=26oC ; pH=7.0-7.2 ; GH=4 ; KH=2

This tank has a very large capacity filter to cope with the waste load from large predatory fish. The external glass unit has a capacity of 27 (34 US) gallons and essentially functions like a sump except that mechanically prefiltered water is pumped to it by a powerhead with prefilter cartridge and flows back by gravity. However, unlike a sump, almost 100% of the capacity is filled with media.

The African tigerfish makes a stunning centrepiece for this tank, cruising slowly or hovering almost stationary in the water until food is thrown in, which results in lightning-fast lunges! The tank also houses several of my large Polypterus collection. Also on an African theme, is the Synodontis catfish - a lovely specimen of one of my favourite Syno's - S. decorus.
