The Aqua-Internal 400 filter is suitable of filtering from 200 to 400 litres of aquarium water. This model is an efficient and quiet dual action internal aquarium filter. The compact Aqua-Internal 400 filter is ideal for use in all types of coldwater and tropical aquariums.
The dual action filter cartridge, contained within the filter, consists of the 3 forms of filtration: mechanical, biological and chemical. The fully open structure filter foam provides optimal mechanical filtration and creates a vast bacterial growth area. The chemical filtration section of the cartridge includes Norit ® active carbon to remove organic contamination, chemicals and dyes from the water.
Employing the ‘Easy-Clean Click System’ ensures that filter cleaning and maintenance is very quick and easy- replacement filter cartridges can be changed with little mess or stress. For the best results and water conditions, we recommend replacing the aqua-internal filter cartridge every month.
For the ultimate filtration and water chemistry, we would highly recommend using the unique 6-stage Aqua Internal ‘Crystal clear’ filter cartridges. Designed to be used with all the Aqua-Internal filter models (excluding the Aqua-Internal filter XL), the Aqua-Internal ‘Crystal Clear’ filter cartridge consists of:
- Fully open structure filter foam, providing optimal mechanical filtration
- Fully open structure filter foam creates a vast bacterial growth area for efficient biological filtration
- ‘Clean Water’ to aid the removal of nitrate
- Norit ® Active Carbon to remove organic contamination, chemicals and dyes
- Zeolite to remove harmful ammonia and heavy metals
- ‘Active Alumina’ to help remove silicates and phosphates from the water- these being an essential nutrient for unsightly algae growth.
