  • Its flow regulation system is unique, with a system that keeps the water inside the filter for longer, to improve quality despite having a lower water flow.
  • Very quiet (one of the most), quick and easy handling.
  • Unbeatable value for money.


  • The only drawback of this filter is in the filtering materials, which, being cartridge type, are proprietary and can entail a higher maintenance cost, although the quality is indisputable.

SunSun CBG-500 Backpack Filter

The SunSun CBG-500 backpack filter is designed to fit in aquariums from 38 liters to 115 liters.
This filter has a couple of details that differentiate it from other waterfall filters:

  • It mounts integrated UV-C ultraviolet light, so that, if we turn it on, we avoid the proliferation of algae … which are extremely annoying.
  • Use a shallow aspiration, similar to a surface skimmer, to improve the oxygenation of the aquarium.
