Care pH Up
What
is pH?
The
measure of the acidity of water is pH. A pH reading of 7.0 is neutral, a
pH higher than 7.0 is alkaline, and lower than 7.0 is acidic. The pH of
pond water will naturally fluctuate, and pond fish and plants are
accustomed to these fluctuations. A pH range between 6.8 and 8.0 is
ideal for garden ponds. However, acid rain, mineral leaching, soil
runoff, and decomposing plant and fish waste can cause unacceptable pH
levels to occur. Some sources of tap water used to fill ponds can also
cause extreme pH levels. A pH below 6.8 or above 8.0 should be avoided.
A pH level of 7.0 is ideal. Low pH levels of less than 6.8 can stress
pond fish and suppress the activity of the biological filter. A high pH
of more than 8.0 will limit the ability of many plants to absorb
necessary nutrients.
Pond
Care pH Up and pH Down adjust the pH in garden ponds by neutralizing excess acid or base. These
products can be used daily to adjust pH until conditions stabilize. pH
Up and pH
Down contain no
algae-promoting phosphates. It is important to accurately measure the
level of pH in a pond before initiating adjustments. Use a Pond Care pH
test kit to measure your pH weekly.
pH
should only be either raised or lowered by no more than 0.5 units every
24 hours. Do not treat pond water more than once every 24 hours. Plants
and algae cause a temporary increase in pH in the afternoon; therefore,
pH should be tested in the morning to obtain the most accurate reading.
Problems of low pH Nearly
all ponds tend to turn slightly acidic (between 6.8 and 7.0) as the pond
life grows. A pH below 6.8 will stress pond inhabitants. A low pH may be
caused by increased carbon dioxide concentrations, the result of
overstocking with fish or poor surface agitation. Proper fish stocking,
as well as adequate pond filters or fountains, will correct carbon
dioxide build-up and help stabilize pH.
A low pH
(acidic water) may also be caused by decomposing organic matter, solid
wastes from fish and birds, and decaying vegetation. The use of Pond
Care® Pond Zyme® Plus and regular pond maintenance will help eliminate
potentially deadly pH fluctuations.
Note: The pH of pond water
goes through a natural “cycle,” fluctuating from day to night.
Plants and algae, through photosynthesis, consume carbon dioxide from
the pond water. This causes a gradual, temporary pH increase during the
day. As sunlight diminishes, photosynthesis slows down and the pH level
drops to the normal level. Testing pH in the afternoon will consistently
give a higher pH measurement, hiding a low pH condition that may arise
in the evening and morning hours. Therefore, it’s best to test pH in
the morning hours before plants become active and pH goes up. Always
test around the same time of day for the most accurate evaluation of
pond pH.
Directions
For Use:
1.
Test the pH level of the pond water to determine if adjustment is
necessary.
2. IMPORTANT: Carefully mix the
appropriate dose with pond water in a plastic container and distribute evenly around the perimeter of the pond.
3.
For Pond
Care pH Up add 2 teaspoonfuls (10 ml) for each 50 US (190 L /42 UK Imp. Gal.)
gallons of pond water.
4.
For Pond
Care pH
Down add 1 teaspoonful
(5 ml) for each 50 US (190 L / 42 UK Imp. Gal.) gallons of pond water.
5.
Wait 24 hours, then test pH levels. Repeat treatment as necessary.
Please
read extra warnings on the label.
Keep
out of reach of children.
