This 153-liter aquarium was acquired used in March 2002 as part of an expansion of my aquarium rack. The tank features an older and quite unique construction with a steel bottom covered by a plexiglass plate, requiring extra attention regarding seals and glass tension.
Technical Challenges and Maintenance
Working with vintage aquariums provides valuable experience but also challenges. Since the bottom is a hybrid of steel and plexiglass, I was initially skeptical about its longevity. After a leak occurred in 2005 during a conversion to a Tanganyika setup, I attempted a thorough cleaning and resealing. While it held for a period, I eventually replaced it with a custom-built aquarium to ensure long-term reliability within my rack system.
Usage for Rearing Fish
The tank primarily served as a rearing environment for Mbuna cichlids from Lake Malawi, including species such as Chindongo saulosi and Pseudotropheus cyaneorhabdos (Maingano). The 153-liter volume is ideal for providing juveniles with the necessary swimming space and stable water parameters before they are moved to larger display tanks. For rearing cichlids, robust filtration and frequent water changes are vital to prevent growth-stunting waste products.
Technical Setup
Filtration was managed by a DIY black filter sponge (40x40x5 cm) powered by two air-driven lifts. This system provides excellent biological filtration and high oxygenation, which is essential for active cichlids. Heating was controlled by a 100W Via Aqua steel heater with an external regulator, offering enhanced safety against overheating.
Status
In January 2006, the aquarium was passed on to another enthusiast alongside the sale of my 650-liter rack, serving as a project for practicing the art of silicone sealing.
