API Pond Ph UP 473ml
Raises pond pH gradually, without a caustic spike. API Pond pH Up is a phosphate-free, nitrate-free buffer that neutralises acidity and lifts a low pond pH back into a safe range for fish and plants – working gradually rather than jolting the water chemistry. This 473 mL bottle doses roughly 8,900 L of pond water at the standard rate, at under 1c per litre treated.
Key features
- Buffers pH upward by neutralising acidic substances in the water, rather than a strong caustic adjustment that can overshoot.
- Phosphate-free and nitrate-free – won't feed algae or unbalance a planted pond the way some pH adjusters can.
- Capped at a 0.5 pH-unit rise per 24 hours by design, so fish aren't shocked by a sudden swing.
- Under 1c per litre of pond water treated – 473 mL doses roughly 8,900 L at the standard rate.

Dosage and directions
- Test pond pH first with an API pond or aquarium pH test kit.
- Add 10 mL (2 tsp) per 190 L (50 US gal) of pond water, ideally into an area of water flow so it disperses.
- Wait 24 hours, then retest before dosing again.
- Do not raise pH by more than 0.5 units in any 24-hour period.
- Test in the morning for the most consistent reading – pond pH naturally drifts up during the day as plants photosynthesise.
Suitable for, and not suitable for
Suitable for:
- Ponds with plants, thanks to the phosphate-free, nitrate-free formula
- Ponds running a persistently low or acidic pH that needs correcting over several days
Not suitable for:
- Rapid correction of a severely low pH in an emergency – the deliberately gradual, capped dosing makes this a maintenance tool, not a fast fix. If fish are in acute distress, address the underlying cause and seek advice rather than dosing repeatedly to force a faster change.
Care and maintenance
Retest regularly rather than dosing on a fixed schedule – pond pH drifts with plant photosynthesis, rainfall and topping up, so dose to a reading in hand, not to a calendar.
Safety and handling
- Keep out of reach of children.
- A Safety Data Sheet is available from API on request.
- Standard handling precautions for pond water-chemistry products apply – avoid skin and eye contact, wash hands after use.
Warranty and delivery
This is a consumable pond treatment, so no manufacturer warranty period applies. That doesn't affect your rights under the Australian Consumer Law – if the product is faulty, unsafe or not as described, you're entitled to a remedy. Ships as standard freight.
Common questions
How fast will this raise my pond's pH?
Dosing is capped at a 0.5 pH-unit rise per 24 hours by design, so expect a gradual change over several days rather than an instant fix.
Is it safe for pond plants?
Yes – the formula is phosphate-free and nitrate-free, so it won't feed algae or unbalance a planted pond.
Can I dose more than once a day to speed things up?
No – do not exceed one dose per 24 hours, and don't raise pH by more than 0.5 units in that period.
When should I test pond pH?
Test in the morning, since pH naturally rises through the day as pond plants photosynthesise.
What if my pond's pH is critically low?
This product is a gradual maintenance buffer, not an emergency treatment. Identify and address the underlying cause of the acidity, and seek professional advice if fish are showing acute distress.
