Zoe Ross –
Used this buffer in my 100L cichlid tank. KH stabilized after a week and my fish seemed more active. No pH spikes, which was a big relief. The instructions were clear and the product worked as expected.
Natalie Smith –
Good for maintaining stable pH. Added it once a month to keep KH consistent. My fish have been more vibrant since switching to this buffer. A bit pricey but worth it for the stability.
Nicola Peake –
Perfect for African cichlid tanks. The KH levels stayed steady and my breeding pair produced healthy eggs. No fluctuations in pH, which helped reduce stress on the fish.
