Grech CBG‑500S – cascade filter

The SunSun CBG-500S is a cascade filter for keepers with aquariums from 38 to 115 l who want a larger filter volume and more space inside the tank. The filter sits outside the aquarium, and its stepless flow regulation lets you match its output to the tank size.

Why it matters

• The filter body is mounted outside the aquarium, which frees up space inside the tank.
• Water returns through the cascade, which aerates the water as it flows back in.
• Three filtration stages run on separate media: a mechanical sponge, bio-ceramic balls of different porosity, and activated carbon. Each stage has its own dedicated basket.
• Two intakes work together: a lower tube draws water from near the bottom, and a surface skimmer removes floating debris and surface film. A regulator on the skimmer tube sets its share of the flow from 0% to 100%.

What it works with

The CBG-500S is intended for aquariums in the 38 to 115 l range, where it is installed outside the tank. Each media basket holds any filter insert you choose, so the mechanical, biological and chemical stages can be adjusted to the needs of your setup. Media trays have a handle, so they can be pulled out quickly for cleaning or replacement.
