OXYGENATING PLANTS For Fools 
Vallisneria 
• Keep the Water Pure and Clear 
• Provide Spawning Space for Fish 
• Shelt er and Protect Baby Fish 
Every pool needs oxygenating plants to keep the water crystal 
clear and pure. These plants grow under water just like plants you 
see growing naturally in ponds and lakes. They absorb impurities 
from the water and liberate oxygen, which action clarifies the water 
and helps to prevent the growth of Algae that turn the water green. 
Oxygenating plants are indispensable when fish are present, as they 
set up a balanced or natural condition of the water. They also will 
assist materially in raising a hatch of baby fishes, as the young fish 
find much needed shelter and protection among their foliage. 
HOW TO PLANT OXYGENATING PLANTS IN POOLS 
Use small boxes or 5-inch pots and plant the oxygenating plants 
in soil. Leave the soil level an inch below the top of the box or pot 
and fill up the remaining space with sand. This prevents muddying 
up the water when the plants are placed in the pool. Place the box 
or pot directly on the bottom of the pool in between the lilies. A fl¬ 
inch pot is large enough to accommodate about three plants. Oxyge¬ 
nating plants should be planted in containers by themselves and should 
never be planted in the same containers with lilies.
