Fritz pH Higher

Fritz pH Higher reduces acidity and raises pH in freshwater aquariums, and it boosts KH (carbonate hardness) at the same time for a more stable, better-buffered system. Adjust gradually to keep your fish comfortable. Explore more water care.

Features

• Raises pH in freshwater aquariums
• Increases KH (carbonate hardness) for better buffering and stability
• Helps hard-water species like African cichlids and livebearers
• Best used in small, gradual steps
• Pairs with pH Lower and pH Neutralizer for full control

Choose Your Size

• 4 oz for smaller tanks
• 16 oz for larger tanks and better value

How to Use

• Test pH and KH before and after dosing
• Do not change pH by more than 0.2 units in 24 hours with livestock present
• As pH rises above 6.0 ammonia becomes more toxic, so keep ammonia in check first
• Add slowly and retest after several hours

Frequently Asked Questions

Does it raise hardness too?

Which fish like higher pH?
Hard-water species such as African cichlids and many livebearers.

Any cautions?
Above pH 6.0 ammonia becomes more toxic, so keep ammonia in check as you raise pH.
