OXYGENATING PLANTS 
to keep the water clear and 
for Pools and 
Aquariums 
pure 
T O INSURE proper living conditions for 
your fish and to keep the water pure and 
clean, water gardens and aquariums should 
be planted with suitable oxygenating plants 
which absorb the impurities and liberate oxy¬ 
gen. With these plants you can provide a bal¬ 
anced condition of plant and animal life and 
remove the need for changing the water often. 
When these plants have been used we have 
known aquariums to be in perfect condition 
after two years without a change of water. 
We offer suitable collections of the right 
varieties to balance the aquarium. Place an inch 
or two of well washed sand or Aquarium Grit 
in the bottom of the aquarium and in this 
plant several varieties of water plants. Plant 
the Vallisneria around the sides and back, and 
Sagittaria just in front of the Vallisneria, and 
bank the sprigs of other plants in the corners 
and at other points for ornamental effect; and 
let Salvinia float on the water. 
AQUARIUM GRIT. Fine grit especially pre¬ 
pared and recommended for growing oxy¬ 
genating plants. 5 lb. bag, 25c; 10 lb. bag for 
12 gal. aquarium 40c; 25 lb. bag for aquariums
