PH and Buffers

Stabilise, Adjust & Maintain Healthy Aquarium pH

Maintaining stable pH is essential for healthy fish, strong biological filtration, and long-term aquarium success. Our pH & Buffer range includes products designed to safely raise, lower, or stabilise aquarium pH levels in freshwater and specialty setups.

Whether you’re keeping African cichlids that prefer higher pH, South American species that thrive in softer water, or managing a planted community tank, choosing the correct buffer helps prevent stress and sudden swings.

Our range includes:

  • pH increasers and reducers

  • KH and alkalinity buffers

  • African cichlid buffers

  • Freshwater stabilisers

  • Water chemistry support products

Stable water parameters reduce stress, improve immunity, and help fish show their best colour and behaviour.

 

What is the ideal pH for aquarium fish?

It depends on the species. Most community tropical fish prefer a pH between 6.5 and 7.5. African cichlids typically require higher pH levels around 7.8 to 8.5.

Should I adjust my aquarium pH?

Only if your fish require different conditions than your tap water provides. Stability is more important than chasing a specific number.

What does a buffer do in an aquarium?

Buffers help stabilise pH by controlling carbonate hardness (KH), preventing sudden swings that can stress or harm fish.
