Brightwell AquaticspH+, pH Increaser for All Marine and Freshwater Aquariums - 500 ml

👍

I like and trust Brightwell products. I have a 29 G biocube reef tank. Because of its small size and absence of a refugium, the pH fluctuates, especially at night. I have a controller and doser to counteract the drop in pH at night and use pH+ to raise the pH. However, I have noticed an increase in alkalinity since using this product. The alkalinity increased from dKH 10 to 11.8. So I now use Balance instead of pH+ as it does not increase alkalinity.

Wow much bigger than expected. Guess I didn’t read the description well. But anyway it’s a lifetime supply. Works very well. I just put in a few drops at a time to bring up the PH slowly so I don’t shock the fish or corals with a significant change. I feel slow change is best.

I had a nitrite spike that stemmed from a pH crash, this product adjusted the pH and increased KH.. the label alone tells you these people know what they’re talking about. Read the instructions, you’ll be enlightened

Love this product and the company that backs it. Had a few questions and the owner and staff was prompt to answer them, and do the research to answer the question right. Above and beyond.

Does what it claims but is super toxic to inverts. Snails and shrimp.

Did what it is made to do.

Finally found a larger bottle of PH. Would buy again.
