## Overview

Brightwell Aquatics pH+ is a 500 ml marine aquarium booster designed to increase and stabilize pH and alkalinity levels, enhancing carbonate buffering to support coral health and growth. Made in the USA with ultra-pure ingredients, it ensures consistent, safe dosing for reef and saltwater tanks, helping aquarists maintain optimal water chemistry and vibrant marine ecosystems.

## Description

Increases pH in marine and reef aquaria. May be used to help increase pH in aquaria that have adequate alkalinity yet have chronically-depressed pH levels; while not intended to act as a permanent solution to such issues, pH+ may be used as needed until the cause of depressed pH is discovered and remedied. Composed of purified water and ultra-high purity materials.

Review: Works perfectly for my nano reef tank. - Does exactly as described. It is a bit of a pain with a six gallon nano reef tank to get the measurement just right. But once I got that figured out the dosing takes the ALK up .2 each day. A nice slow climb. Works perfectly.
Review: Easy to use - Great for saltwater tank
