For the pictures I used an illuminated white cardboard for an "infinite background" effect.
6500k 23w compact fluorescent at about 20cm from the water surface. 9 hours of light a day.
No filtration. 100% of water changed on a weekly basis with untreated hard tap water.
Compressed CO2 injected through a wood airstone. Water parameters unknown, I don´t test anymore. I dose nutrients according to the appearance of plants and the presence of algae. Fertilization involves the addition of tiny amounts of KH2PO4, K2SO4, KNO3 and a trace mix every few days. At the time the pictures were taken the tank was four months old.
This is not such a high maintenance tank as it may seem, plants don´t grow as fast as they usually do in other tanks, probably due to the lack of water movement.
I often take an experimental approach to projects, whereby aquascapes are created through the exploration of a particular process rather than specifying a predetermined outcome.
