A Balanced Aquarium is Well Planted 
A “balanced aquarium” is one in which the air surface of 
the water supplemented by the cxygen given off from the 
plants, provides sufficient oxygen in the water to support the 
life of the fish in the aquarium. The plants in giving off this 
life giving and water purifying oxygen, absorb harmful gases 
and carbon dioxide from the fish. It is the plants that keep the 
water fresh and clear, eliminating the necessity of changing 
the water in the aquarium. 
Aquatic plants are the most important of the aquarium equip- 
ment and more than half the beauty. The natural beauty of 
aquatic plants serves as a pleasing background to enhance the 
exotic color of your fish. 
Aquatic Plants need to be planted in “well-washed” aquar- 
ium gravel only; no soil is necessary. Gravel should be placed 
in the aquarium 2¥2 to 3 inches deep in the back, sloped to 
2. inches deep in the front. Planting is done with the aquarium 
at least two thirds full of water. The roots of the plant should 
be gently pushed into the gravel and covered up to the crown, 
leaving the crown exposed. The arrangement of the plants in 
the aquarium is a matter of taste. Generally the taller plants are 
placed in the back with the smaller and more showy specimens 
towards the front. Plants require 8 to 10 hours of good light 
each day; they will grow equally well in sunlight or artificial 
light provided by an aquarium reflector.
