The API® Phosphate Test Kit tests phosphate levels from 0 to 10 ppm so that you can easily monitor the condition of your aquarium water. May be used in both fresh and saltwater aquariums.
Phosphate can enter your aquarium through tap water, fish waste, and decaying organics such as uneaten food and dead algae. Excess phosphate contributes to unsightly algae and green water blooms, and in saltwater, excess phosphate can inhibit the growth of hard corals.
We recommend that you take a few minutes each week to monitor your aquarium conditions and create a better underwater world for your fish. Testing your aquarium water has never been so easy or accurate!
Contains 150 tests and includes 2 test solutions, easy-to-ready instructions, glass test tube and 2 color charts
This test kit reads the total phosphate level in parts
per million (ppm), which are equivalent to
milligrams per liter (mg/L) from 0 - 10.0 ppm
(mg/L).
Directions
To remove childproof safety cap: With
one hand, push red tab left with thumb
while unscrewing cap with free hand.
1. Fill a clean test tube with 5 ml of water to
be tested (to the line on the tube).
2. Holding the bottle vertically, add 6 drops from
Phosphate Test Solution #1. Cap the test
tube and shake vigorously for 5 seconds.
3. Now, holding the bottle vertically, add 6 drops
from Phosphate Test Solution #2.
Note: Test Solution #2 is a very thick solution
and may require increased pressure to release
drops.
4. Cap and shake the test tube vigorously for
5 seconds.
5. Wait 3 minutes for color to develop.
6. Read the test results by comparing the color
of the solution to the appropriate Phosphate
Color Card (choose either Freshwater or
Saltwater). The tube should be viewed in a
well-lit area against the white area of the
card. The closest match indicates the ppm
(mg/L) of total phosphate (PO4
3–) in the water sample. Rinse the test tube with clean water
after use.
What the Test Results Mean
Ideally, the phosphate level should be 0 in
aquariums (and ponds). The phosphate level in a
new aquarium will depend on the purity of the
water used to fill the aquarium. The phosphate
level in tap water can vary daily depending on
the treatment process used. Phosphate tends to
accumulate in established aquariums.
Reducing Phosphate Levels
To quickly reduce phosphate, perform a partial
water change. Remove any dirt and uneaten fish
food from the bottom of the aquarium and
change 25-50% of the water, depending on the
phosphate concentration.
