Brightwell Aquatics PH+
The Brightwell Aquatics PH+ is a specialized solution designed to increase pH levels in marine and reef aquaria. It is particularly useful in tanks with adequate alkalinity but experiencing chronically low pH levels. While not intended as a long-term fix for underlying pH issues, pH+ can be used as needed until the root cause is identified and addressed.
Formulated by a marine scientist and composed of purified water and ultra-high purity materials, pH+ delivers stronger performance than most competing products. Its high purity ensures minimal contamination and safe use in sensitive aquatic environments.

| Not a permanent solution | Use only when pH is chronically depressed and alkalinity is sufficient |
| High purity formulation | Contains purified water and ultra-high purity materials |
| Scientifically developed | Created by a marine scientist for accurate and safe performance |
FAQ
Can pH+ be used in tanks with low alkalinity?
No, pH+ is intended for use in tanks with adequate alkalinity but chronically depressed pH levels. It is not recommended for tanks with low alkalinity, as it will not address the underlying issue.
How often should pH+ be used?
Use pH+ as needed when pH levels drop below the desired range. Monitor pH regularly and adjust only when necessary to avoid over-correction.
Is pH+ safe for reef tanks?
Yes, pH+ is formulated for use in marine and reef aquaria and is safe when used according to recommended guidelines.

Wanda Wright –
I’ve used pH+ in my 100-gallon reef tank for several months. The pH stabilized quickly after a drop, and the water remained stable without any noticeable changes in coral health. It’s effective and easy to use.
Nicholas Skinner –
The product works well when pH dips below 8.0. I added a small amount every few weeks and noticed a consistent improvement. I still monitor alkalinity levels to ensure long-term balance.
Eric Hodges –
As a reef keeper, I was cautious about pH adjustments. pH+ gave me confidence to maintain stable conditions without over-treating. The formulation feels clean and safe.
