Aquafix NO3 is a nitrate-removing bag for freshwater aquariums, intended for keepers whose tanks regularly show high NO3 readings or excessive algae growth. It is placed inside the filtration system, so it can be used without changing the filter setup or the aquarium layout.
Why it matters
- The bag is placed in the filter, so the medium works on the water as it passes through the filtration system.
- The supplier specifies a reduction from 40 mg/l to 20 mg/l NO3 in a 50-litre tank.
- Effect time ranges from a few hours to 1–2 days, depending on water flow through the filter.
- The medium can be regenerated with kitchen salt, so it can be reused instead of replaced after each cycle.
