Brightwell Aquatics Florin pH- safely decreases pH in the planted marine aquarium, where for example macroalgae has increased the pH too much. May also be used for freshwater aquariums . Gradually decreases alkalinity ("carbonate hardness") of the aquarium water. Contains no phosphate or nitrate.
BRIGHTWELL Florin pH- / PH Minus 250ml / 500ml
Do not add Florin pH- to an aquarium without first determining pH and alkalinity with an accurate meter or test kit. Shake bottle before each use. Read entire instructions before proceeding.
Aquarium addition: Add up to 1 ml Florin pH- per 37.9 L in system every two hours until pH has decreased and stabilized at or near the desired level; note that the rate of water circulation in the aquarium will impact the speed with which the active ingredients alter the pH of the system (faster circulation will decrease the time required for pH to change), and that pH stabilization may take up to 24 hours in extreme cases (it is far more likely to stabilize in less than 2 hours, however).
Do not enact changes in pH of greater than 0.1 per 30 minutes. As Florin pH- is added to the system, alkalinity will decrease, causing pH to become less-stable and eventually decrease, also. In alkaline water conditions, it is common for pH to decrease temporarily and then increase slightly following addition of Florin pH-; this is simply due to interaction between the active components and the buffering molecules present in the water, and will gradually lessen as alkalinity decreases. At that point, pH will change easily with addition of Florin pH-, therefore proper caution should be exercised to ensure that pH does not drop below a safe level. Consult a reputable reference for alkalinity and pH requirements of the organisms being housed in the aquarium and make adjustments to these parameters as necessary to attain the desired values. Alkalinity may be increased through the use of a buffer (such as Brightwell Aquatics Florin Delta KH+); this will stabilize, and potentially slightly increase, pH.
Contains buffered sulfuric acid; contents may be corrosive and/or irritating. Do not breathe fumes. Keep out of reach of children. Not for human consumption. First Aid: If swallowed: rinse mouth, give water or milk. Do not induce vomiting. In the event of eye or skin contact, flush with water for at least 15 minutes. Contact a physician immediately.
