Omega One Veggie Rounds Food (Various Sizes)
Lowers KH to lower pH in stubbornly high pH water.
Uses: Acid Buffer™ is used in conjunction with Neutral Regulator™ when the pH is very high or is difficult to lower to 7.0 with Neutral Regulator™. It reduces the carbonate hardness (KH) of the water, making the pH much easier for other products to buffer. If your pH is very high and resistant to buffering, Acid Buffer™ is your answer! Consider using with our other products.
From the manufacturer: Acid Buffer™ is a non-phosphate buffer to lower pH and buffer with Alkaline Buffer™. Both buffers are designed for the planted aquarium or for very hard water where phosphate buffers may pose an algae or cloudiness problem. Acid Buffer™ lowers pH and buffers the water effectively.

FAQ
Can Acid Buffer™ be used alone to lower pH?
No, Acid Buffer™ is designed to be used in conjunction with Neutral Regulator™ when pH is very high or difficult to adjust. It reduces KH to make pH easier to stabilize with other products.
Is Acid Buffer™ safe for planted aquariums?
Yes, it is specifically formulated for planted aquariums and hard water conditions. It does not contain phosphate, which helps prevent algae growth and water cloudiness.
What happens if I use Acid Buffer™ without Alkaline Buffer™?
Using Acid Buffer™ without Alkaline Buffer™ may lead to unstable pH levels. Both products work together to maintain balanced buffering in the water.


Sam Wright –
I’ve struggled with high pH in my planted tank for months. After adding Acid Buffer™ with Neutral Regulator™, the pH stabilized quickly. The water clarity improved and my plants grew more vigorously. No algae issues so far. Highly recommend for hard water setups.
Pippa Churchill –
Works well when pH is stubbornly high. I used it with Neutral Regulator™ and saw a noticeable drop in KH. My tank became more stable, and my plants are thriving. A bit expensive, but effective.
Donna Buckland –
Finally found a non-phosphate buffer that works without causing cloudiness. My tank has been stable for over two months now. The combination with Alkaline Buffer™ gives excellent pH control in hard water.
