Aquascape Details

Tank Size
70 x 70 x 70 cm (28 x 28 x 28 in)
Volume
340L (90 gallons)
Background
250 micron black plastic sheeting
Lighting
5x T5’s grouped 2-2-1 and switched on at staggered 30 minute timed intervals to simulate sunrise, and off again to simulate sunset. The lights are all on together for 6hrs only.
Filtration
Canister Filter (700L/hr) is used mainly to provide slight water movement. The plants do the main filtering.
Additional Information
Research for this low-tech biotope (set up in November 2008) was done on the internet. Maintenance is minimal. I only change 20% water once every 3 months and add a liquid plant food made by a local biochemistry professor. I rinse the filter sponges every 12 months and only trim plants when they block my view, or the light. No CO2 is added.
