Brightwell Aquatics pH+ Liquid pH-Increaser for all Marine Aquaria.
pH is a measurement of the acidity of a solution, such as aquarium water. The pH of natural seawater ranges from approximately 8.2 - 8.4, however maintaining pH in the range of 8.1 - 8.5 on a daily basis has no negative impact on captive marine organisms.
To maintain stable pH within the desired range, the alkalinity should be maintained within a range of 7 - 12 dKH (2.5 - 4.3 meq/L). Aquaria with low circulation at the water’s surface, in which a CO2-injected calcium reactor is being employed, or in which a carbonate-deficient sea salt blend has been used, often have depressed pH. pH+ will bring pH in the aquarium back into the desired range.
Use as directed and do not exceed a pH value of 8.5, as this pH may be stressful and/or fatal to sensitive aquarium inhabitants. Additionally, changes to pH should be made very gradually, again to avoid stressing aquarium inhabitants.
It is not unusual for pH to fluctuate throughout the course of 24-hours between seemingly wide-ranging values (i.e. 8.1 at night to 8.4 during the middle of the day); this is a natural occurrence that is caused by changes in the rates of photosynthesis between dark and light periods. This situation is frequently encountered in aquaria with considerable growth of macroalgae (in the display aquarium or in a refugium).
One proven method of minimizing this daily pH-fluctuation is to implement a refugium that is illuminated on an opposite schedule to the lighting for the display aquarium (known as reverse-daylight photosynthesis). In this method, the refugium is illuminated at night when the display aquarium lights are turned off, and vice versa; a 1-hour overlap of having all lights on encourages a smooth transition and little change in pH. The result is that photosynthesis takes place 24-hours a day and keeps pH as stable as can be managed.
If pH levels are seen to be constantly below the desired level and alkalinity is within the proper range, increasing the circulation of water near the aquarium surface will often produce positive results; this practice increases the rate of gas exchange and encourages entrained CO2 to exit the aquarium before it has a chance to form the weak acids responsible for low pH and depletion of alkalinity.
Hanna reagent for the HI-781 Low Range Nitrate Checker
About 25 tests per pack.
Only scientifically described in 2001, the Coral Red Pencilfish has a red body with two bold horizontal black lines. It is regarded as one of the most beautiful pencilfish.
To distinguish the males and females apart are simple. The male has a white flash on dorsal while its anal fin is entirely red. The female on the other hand have no white flash on dorsal fin, anal fin broader than the male with a clear border.
Due to its colouration it is very eye-catching and an active fish. The Coral Red Pencilfish should be kept in a group of at least 6 fish. Remaining relatively small and barely reaching over 1 inch (2.9)cm in length, it makes a great addition to any community tank. However, it would not do well with larger fishes as they are easily intimidated. They are peaceful and are not aggressive towards other species, so the Coral Red Pencilfish makes good community fish.

The HI702-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Copper High Range Checker® HC. These reagents follow the Bicinchoninate Method in which the reaction between copper and the reagent causes a purple tint in the sample. By simply adding the packet of HI702-25 reagent to the sample, the reaction will take place and the HI702 will determine the concentration from the color that is produced. The results will be displayed in ppm of copper. These reagents are designed to be used with samples that have an expected range of 0.00 to 5.00 ppm copper.
The HI702 Checker is a simple, accurate, and cost effective way to measure high ranges of copper. Designed as a more accurate alternative to chemical test kits, the HI702 provides quick, accurate results in a few easy steps.
