Tetra pH test solution (freshwater only)

Utility:
Accurate test PH value.

IMPORTANT:
Freshwater Tetra pH test solution dedicated to freshwater tank， pond water quality testing， do not test the water， so as not to produce incorrect results.

Instructions:
1. First I want to test the water with a little of the wet test bottle.
2. Add 5 ml water to be tested.
3. The reagent is added 7 drops in vertical test bottles.
4. slightly shaking.
5. The test bottle color control and color table， you can know the PH value

TetraGeneral hardness (GH)
Water hardness can significantly affect aquatic organisms organic function. General hardness (GH) and carbonate hardness (KH) is different. General Hardness (GH) is characterized by a basic salt， and carbonate hardness (KH) buffer PH value of the play. Calcium / magnesium are used to calculate the amount of general hardness. A large number of accounts for the formation of hard water when it is formed when accounting for a small amount of soft water.
TetraCarbonate hardness (KH)
In addition to calcium and magnesium salts， almost all of the water contains other salts (such as bicarbonate). Carbonate hardness and pH value will be interdependent.
Test Procedure GH and KH:
1. To test the water rinse test tube
Water is charged 5ml 2. will want to test into the test tube. If with 10ml water tank to measure， the accuracy can be increased.
3. Hold the test tube， reagents inverted， dropped a drop of reagent test tube.
4. Each drop of reagent that is gentle shaking test tubes， when required to calculate the color reagent test tube of water.
5. Test GH， the color will turn from red to green.
Test KH， the color will turn from blue to yellow.
6. If only produce a drop of reagent， color change， representing a value of1 dGH??
7. dropped a few drops of color change， which represents the hardness， for example: 3 drops = 3dH. If the test works 10ml water tank to be tested， 1 drop reagents Representative1 dGH equivalent to 100 ml of distilled water containing 1 mg of the calcium oxide content.?? Test finished， rinse with tap fully.

Deutsche color NO2 nitrite test kits the test agent

Use times: 40-45 times lighter seawater dual

Whether the deterioration of the water， whether fish because nitrite poisoning， whereby the test solution may be sensed aquarium water quality.

The fish excrement， not eating food， plants and other organic matter is decomposed through microbial action to decompose into ammonia， ammonia is further broken down into nitrite， thus the formation of nitrates.

When nitrite is high， representing the aquarium biological filtration system is a problem， the ideal nitrite value should be 0 to 0.3 mg / liter of water， and can not exceed 0.8 mg / liter of water， when the value of more than 1.6 mg / liter of water of the fish and cause injury. Water should be tested weekly to ensure that nitrite value is within a safe range.

Use Tetra test liquid can be measured is less than 0.3 mg / liter of water nitrite.

Instructions:
l. The water to be measured into the test equipment 5c.c. bottle.
2. trickle l No. 7 drops of reagent bottle， even slightly shaken.
Plus 2 drops of reagent 7 seconds after 3.l0， slightly shaking evenly.
4. After 2 to 5 minutes with standard color stable color than the color， it can be measured to determine the content of nitrite in water quality

Tetra Test NO3 nitrate content agents (light， water and night)

Capacity 19mL × 1， 10mL × 2， × 1 powder

Nitrate content of the test can test out the tank contaminated the case， the test results is to decide when to change the water， changing how much water the best indicator of how much water the change， the fish droppings， not eating food， are decomposed aquatic plants， etc. There are slight biological effects of nitrogen decomposed further break down ammonia into nitrite， thus the formation of nitrates. Although nitrogen is the kind of plant nutrition， as when water exceeds 50 milligrams per liter nitrogen content that would harm fish.

??Standard Usage??

1. First I want to test the water with a little of the wet test bottle， then add 5 ml of water to be tested

2 One vertical reagent was added 14 drops in test bottle

3 slightly shaking

4 reagent was added 7 drops 2 vertically and slightly shaking the test bottle

5 added a teaspoon of powder test

6 capped， wait 20 seconds

7 reagent was added 7 drops 3 vertical and slightly shaking the test bottle

8 Wait 10 minutes to wait for color

9 test bottle color on the color table control， you can know the nitrate content of the water

NOTE: Each test is completed， test the water bottle required a thorough cleaning.

TetraNH3 / NH4 (ammonia)
Talk correct measurement of ammonia content in water and seawater

Test Procedure
Please read this section carefully before testing， the treasure mortem test ammonia (NO3) / ammonium ion (NH4 +) from 0mg / 1 ~ 5.0mg / l
1. To test the water washing test tubes， mounted 5ml water to be tested into the test tube， Note: To measure water temperature must be between 20 ~ 30 .
2. Reagent 1 inverted， adding 14 drops of reagent drops in the test tube.
3. Cover the test tube after a jog.
4. Open the test tube， the test agent 2 inverted， added 7 drops of the test agent to the test tube.
5. jiggle test tube.
6. Reagent 3 inverted， added 7 drops of reagent to the test tube.
7. jiggle test tube.
8. wait 20 minutes (at room temperature) in order to make color formation.
9. For the jiggle test tube and test tube color and color table control， the test tube placed in the white part of the color table at 1 cm (one finger width) than the color of the color table to a recent test finished， filled with tap water Rinse parts.

Numerical and Evaluation
0mg / l: the ideal state.
0.25mg / l: long-term toxic will need to observe the PH value of the sea water tank is very important.
1.5mg / l: only toxic to fish， decomposition of harmful substances have been severely damaged.
3mg / l: only deadly to sensitive fish， decomposition of harmful substances can not be.
5mg / l: lethal toxicity， fish tank has been seriously polluted.

If the ammonia content is too high， how do I do it?
Partial water changes until the ammonia content in water of less than 0.25mg / l.
Use Tetra Gravel Cleaner， with siphon replace at least 30 percent of the tank water.
Tetra Gravel Cleaner can remove the tank， such as food scraps and other waste， must be used every time you change the water with tap water stabilizer (Tetra AquaSafe) adjusting the water added to the aquarium water Tetra SafeStart adjustable phase and aquatic organisms decompose ammonia ??
