Aqua-Pics KH+7.0 Buffer 250g
When pH instability is a problem and pH Up or pH Down are not fixing it (as they are simply band aids on the problem), the solution lies in raising the KH (carbonate hardness) of your water. Neutral KH 7.0 Buffer raises KH, adjusts pH up or down as required and locks pH at around 7.0. This stops pH fluctuation, reduces stress on fish and contributes to their good health and longer life. Contains chemically clean phosphates, which should not exacerbate algae.
Directions: 1 level teaspoon or 5g to 10 litres of water will raise KH by approximately 8dKH or 143ppm and stabilise pH to around 7.0.

FAQ
Can this buffer be used to lower pH in addition to raising KH?
Yes, the buffer can adjust pH up or down as required while raising KH, helping to stabilize pH around 7.0.
Is this product safe for fish and plants in an aquarium?
Yes, it is formulated to reduce pH fluctuations and minimize stress on fish. The clean phosphate content is designed not to promote algae growth.
How much should I add to my aquarium water?
One level teaspoon or 5g per 10 litres of water will raise KH by approximately 8dKH and stabilize pH to around 7.0.

Used this buffer in my 100L tank after experiencing frequent pH swings. After one dose, the pH stabilized at 7.0 and my fish showed less stress. No algae issues noticed. Works well with my existing water chemistry.

Helped reduce daily pH fluctuations in my planted tank. Added once a week as needed. The water feels more stable now and my shrimp are active and healthy.

After switching from pH up/down solutions, this buffer has eliminated the need for frequent adjustments. The KH level stays consistent and fish seem more vibrant.
