pH + is a preparation increasing the pH of the water in marine and freshwater aquariums. The product is available in 3 sizes:

125 ml
250 ml
500 ml
Purified water, inorganic carbonate salts

General information:
Increases the pH level of the water in marine and reef aquariums.
It helps to raise the pH of the water in aquariums that have an adequate level of alkalinity, but that have a chronic drop in pH. Used as an ad hoc, temporary solution until the causes of the drops in water pH are found and eliminated.
More concentrated than most competing products.
Composed of purified water and ultra-pure ingredients of the highest quality.
Formula developed by specialists in the field of marine science.
Instructions for use:
The pH level always reaches its lowest value a few hours after the main light is turned off in the evening, and the highest value – a few hours after it is turned on during the day. Always keep the pH level of the water in the range 8.1 to 8.5. Before adjusting the pH level, make sure that the alkalinity of the aquarium water is between 7 and 12 dKH (2.5-4.3 meq / l). Before using Brightwell Aquatics pH +, determine the pH level of the aquarium water with an accurate aquarium test or a freshly calibrated pH meter. If the alkalinity level is below the desired range, first adjust it, wait 24 hours, measure the pH level again, and then use the pH + preparation according to the instructions. [The alkalinity of water can be increased by using buffering preparations according to their instructions for use. During the process of adjusting the alkalinity level, it should be measured with a thorough aquarium test. Alkalin8.3 and Alkalin8.3-P (powder) are two examples of buffering agents that are perfect for this type of treatment.]
Use the preparation every day at the same time, not exceeding the daily dose of 5 ml of the preparation per 75.7 l of water. The pH level usually stabilizes within 2 hours of using the preparation, however, remember not to expose living organisms to pH changes exceeding 0.2 a day and, as a result, not to overdose the preparation. Repeat the dosage of the preparation until the desired pH level is achieved. It is recommended to keep the pH level in the range +/- 0.2.

Detailed information:
The pH scale is used to measure the acidity of a solution, e.g. in aquarium water. The pH level of natural seawater is in the range from 8.2 to 8.4, however, keeping the pH level of the water in the range from 8.1 to 8.5 on a daily basis does not adversely affect the marine organisms living in the aquarium. In order to maintain a stable pH level in the desired range, maintain the alkalinity level of the water in the range of 7 to 12 dKH (2.5-4.3 meq / L). Aquariums with low surface water circulation, which use a calcium reactor with CO2 dosing, or mixtures of sea salts with insufficient carbonate concentration, often have a reduced pH level. The pH + preparation restores the desired pH level in the aquarium water.
Use according to the instructions. Do not exceed a pH of 8.5 – too high a pH level may stress the aquarium inhabitants and / or lead to the death of more sensitive individuals. Changes to the pH level should be made gently and gradually. Seemingly large fluctuations in pH (e.g. from 8.1 at night to 8.4 in the middle of the day) over 24 hours are a natural phenomenon that occurs as a result of changes in the intensity of photosynthesis during the night and during the day. The described phenomenon is often observed in aquariums where there is a significant growth of macroalgae (e.g. in an exhibition aquarium or a refugium).
A proven method of minimizing daily pH fluctuations is the use of a refugium illuminated contrary to the lighting schedule of the exhibition aquarium (i.e. the use of the so-called reverse photosynthesis). In the above method, the lighting of the refuge takes place at night, when the lighting in the exhibition aquarium is turned off, and vice versa. It is recommended that the times when the lighting is on in both tanks should be the same for 1 hour a day – this will allow for a gentler transition between lighting states and will have a slight impact on the pH change. As a result of the above activities, photosynthesis takes place 24 hours a day, thanks to which the pH level of the water is very stable. If the pH level is consistently below the desired range and the alkalinity of the water is in the correct range, positive results are often achieved by increasing the circulation of water close to the aquarium surface. This action increases the rate of gas exchange and helps release and remove CO2 from the aquarium before it has time to affect the formation of weak acids responsible for low pH levels and a decrease in alkalinity.
