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 5-inch pot is large enough to accommodate 
about three plants. Oxygenating plants should be 
planted in containers by themselves and should 
never be planted in the same container with lilies. 
@ KEEP THE WATER PURE AND CLEAR 
@ PROVIDE SPAWNING SPACE FOR 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 Al- 
eae that turn the water green. Oxygenating 
plants are indispensable when fish are pres- 
ent, as they set up a balanced or natural con- 
dition of the water. They also will assist ma- 
terially in raising a batch of baby fishes, as 
the young fish find much needed shelter and 
protection among their foliage.
