Oase AquaActiv OxyPlus 500ml

Measured short-term oxygen support for warm weather and stressed pond systems

OxyPlus is a controlled-release oxygen treatment designed to raise available oxygen quickly and continue releasing it for several days. It can support the pond during warm weather, after an oxygen-consuming treatment or where temporary conditions have reduced gas exchange.

Use it as short-term support while correcting the cause. Fish gasping at the surface, a stopped pump, a blocked filter or a major algae die-off is an emergency: restore circulation and aeration immediately rather than relying on a powder alone.

What this treatment is designed to do

• Adds oxygen quickly after the measured dose is applied.
• Continues releasing oxygen over several days.
• Supports aerobic biological activity and self-cleaning processes.
• Helps reduce the conditions in which harmful fermentation gases form.
• Treats up to 10,000 litres.

How to use it responsibly

Calculate pond volume, spread the label dose as directed and keep pumps and air systems running. Watch fish behaviour and test ammonia, nitrite, pH and temperature where oxygen stress is suspected. Warm water holds less oxygen, so long-term protection normally comes from properly sized continuous aeration.

• Never regard OxyPlus as a replacement for a failed air pump or circulation pump.
• Avoid adding repeated doses without identifying why oxygen is being consumed.
• Take extra care after algae treatment, during hot nights and in heavily stocked koi ponds.

Calculate the real water volume after allowing for shelves, stone, pipework and filter chambers. If fish are distressed, oxygen is low or the water values are unsafe, stabilise the system before carrying out non-essential cosmetic treatment. Always retain the batch label and follow the current pack instructions, because formulation and regulatory directions can change.

Verified size and coverage information

Use it as part of the whole pond system

For continuous oxygen, compare our pond air pumps, air stones and accessories and filter bacteria. For organic silt, see SediFree.

No bottled treatment replaces adequate filtration, oxygen, sensible feeding and routine removal of organic waste. Used for the correct problem, however, it can be a useful part of a measured maintenance plan rather than a guess-and-hope fix.

Frequently asked questions

Can OxyPlus replace an air pump?

No. It provides temporary oxygen support. A stocked pond generally needs reliable continuous circulation and often dedicated aeration.

When is oxygen most likely to fall?

Warm weather, overnight plant respiration, pump failure, heavy stocking, excess feeding and decaying algae can all reduce available oxygen.

Should I test the pond as well?

Yes. Oxygen distress can occur alongside ammonia, nitrite or pH problems, so water testing and equipment checks are important.
