I like and trust Brightwell products. I have a 29G Biocube reef tank. Due to the small size and lack of refugium, the pH fluctuates especially at night. I have a controller and dispenser to counteract the pH drop at night and use pH+ to raise the pH. However, I have noticed an increase in alkalinity after using this product. Alkalinity increased from dKH 10 to 11.8. So now I use Balance instead of pH+ as it doesn't increase alkalinity.
