TROPICAL pH TEST 4.5-9.5

 

TROPICAL pH TEST 4.5-9.5 is designed for measuring the pH level of fresh and salt aquarium water within the range 4.5-9.5 at intervals of 0.5 pH.

 

What is pH?

pH is the measure of the concentration of hydrogen ions [H+]. It is expressed on a scale from 0 to 14. The pH level determines the aquarium water as acidic (pH<7), neutral (pH=7), or alkaline (pH>7).

 

Why is it necessary to monitor the pH of the aquarium water?

The pH of the water is one of the most important parameters in determining the health and survival of fish, and it is also of significance for aquatic plants. Most of the fish species kept in aquaria do well in water with a pH of 6.5-7.5, but some species require water with a much lower or higher pH in order to remain in good health and reproduce. One must prepare appropriate water for them and then regularly monitor parameters such as: pH and general and carbonate hardness using TROPICAL pH TEST 6.0-7.8, TROPICAL pH TEST 4.5‑9.5 and TROPICAL GH/KH TEST. It is also essential to check the pH in new tanks before introducing any fish; after significant (30-40%) water changes; when cultivating aquatic plants that require fertilizers and/or carbon dioxide (CO2) fertilization; and as part of the regular monitoring of water parameters in any aquarium.

CAUTION! Increasing the pH of the water to above pH 7 will result in the simultaneous conversion of ammonium ions (NH4+) present in water into ammonia (NH3), which is toxic to fish. Before deliberately increasing the pH of the water it is advisable to check the concentration of ammonium ions and, if this is significant, to perform a partial water change.

 

How do fish react to incorrect pH?

Mucus hyperproduction, lethargy, nervousness, and increased susceptibility to diseases are common signs in fish long kept in water with unsuitable pH level. The pH should be adjusted gradually by partial water changes (gradually adding water with suitable pH). Sudden changes of pH level may cause acidosis or alkalosis in fish. In such cases the fish may dart around rapidly, try to jump out of the aquarium, and experience serious respiratory distress. In the event of acidosis or alkalosis an immediate partial water change (ca. 30%) should be made using water with a near‑neutral pH. Thereafter the pH should gradually be adjusted to that appropriate to the species in question. Acidosis and alkalosis typically result in severe gill and skin damages with small likelihood of saving the sick fish.

 

When does the pH level decrease?

§  During filtration through peat, which releases humic acid.

§  When wood, coconut shells, alder cones, oak leaves, etc. have been placed in the aquarium.

§  As a result of the biological decomposition of organic wastes.

§  When fertilising plants with carbon dioxide (CO2).

§  As a result of intentional acidification of the water using pH adjusters such as TROPICAL Aquacid pH Minus.

 

When does the pH level increase?

§  When limestone or shells have been used as a decor.

§  When coral gravel or crushed limestone have been used as a substrate.

§  During intensive photosynthesis in plants in brightly lit aquaria.

§  As a result of intentional alkalisation of the water using pH adjusters such as TROPICAL Aqua-Alkal pH Plus.

 

Adjusting the pH:

We recommend using appropriate pH adjusters such as TROPICAL Aquacid pH Minus or TROPICAL Aqua-Alkal pH Plus to adjust the pH of the aquarium water.

 

Instructions:

1.   Rinse the phial 3 times with aquarium water.

2.   Pour 5 ml of the water to be tested into the phial.

3.   Add 4 drops of the reagent and shake the phial gently.

4.   Compare the colour of the sample with the colour scale provided, under natural light and viewing from above.

5.   After the test is completed, rinse the phial thoroughly under running water.
