Frequently Asked Questions
What's the difference between the 2cm balls and the 5cm ball?
What's the difference between the 2cm balls and the 5cm ball?
Both come with the same gel and release the same trace elements, co-substrates and minerals. The 2cm balls option gives you several smaller balls to spread through the pond or filter, while the 5cm ball option is one larger piece that dissolves from a single spot.
Can I use this in a pond with fish?
Can I use this in a pond with fish?
Yes, it's suitable for all pond types. If fish are present, place the ball inside the enclosed net before adding it to the water.
Will this clear up green, algae-affected water?
Will this clear up green, algae-affected water?
No. DuoBoost works on pond biology and water clarity through biological balance. For green water caused by algae, you'll need a UVC clarifier as well, sold separately.
How often can I use it?
How often can I use it?
Treatment can be repeated several times a year if needed.
Where do I add the gel and ball?
Where do I add the gel and ball?
Both go straight into the pond or the filter chamber, no mixing or dosing equipment is required.
This two-phase treatment helps support healthy, balanced pond biology in ponds of any type, including those with fish. The bacterial gel breaks down organic dirt, ammonium and nitrite while activating your filter bacteria, and the dissolving mineral ball then feeds trace elements and minerals back into the water over the following weeks. Choose between a pack of 2cm balls or a single 5cm ball alongside the 250ml gel, and use the enclosed net if your pond holds fish.
Overview Oase AquaActiv DuoBoost is a two-phase pond water conditioner: a fast-acting bacterial gel paired with a slow-dissolving mineral ball that work together to support pond biology. It suits pond keepers who want ongoing biological support rather than a single quick fix, and it's intended for all pond types, including those stocked with fish.
The gel goes straight into the pond or filter chamber, where its enzymes and bacteria break down organic dirt, ammonium and nitrite while activating the filter bacteria already present. The ball then continues the job over the following weeks, dissolving gradually to release trace elements, co-substrates, minerals and other additives that are otherwise hard to introduce into an artificial pond.
Treatment can be repeated several times a year if needed. DuoBoost supports clear, balanced water through better biology, but it doesn't treat green water caused by algae; for that, you'll need a UVC clarifier as a separate purchase.
Key benefits
- Two-stage action covers both immediate cleanup and longer-term mineral support, rather than relying on one dose to do both jobs.
- Gel and ball go straight into the filter or the pond, with no mixing or dosing equipment required.
- Suitable for all pond types, and safe to use around fish when the ball is placed inside the enclosed net before adding it to the water.
- Releases trace elements, co-substrates and minerals that are otherwise difficult to add to an artificial pond.
Choosing your size The two ball options use the same gel; the difference is in the ball itself. The 2cm balls option gives you several smaller balls to spread through the pond or filter, while the 5cm ball option is one larger piece that dissolves in a single spot.
