Brightwell Alkalin8.3-P 500g - ALKP500Highly effective alkalinity increasing (buffer) powdered blend. Helps increase pH stability in an aquarium by raising the alkalinity; continued addition raises pH until 8. 3 is reached, at which point the pH remains unchanged and the alkalinity alone increases. Provides a source of carbonates, which make up the majority by weight of aragonite, the mineral secreted by reef building organisms as skeletal material. Formulated by a marine scientist.

Amazing!!!
These vitamins have helped me so much. After about a month I could really tell the difference. I suffer from dehydration a lot and this has been a life saver. Pill size is small. Great value for the money. Would highly recommend this!!!
