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.
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.
