The D-D ClariSea SK-3000 Gen 3 is the industry-leading automatic roll filter system designed to completely replace messy, high-maintenance filter socks. Engineered for aquariums up to 600 liters, the ClariSea Gen 3 continuously strips suspended detritus, micro-algae, uneaten food, and organic waste from the water column before it breaks down into nitrates and phosphates. Featuring a factory pre-assembled body, drop-in fleece loading, and an intelligent multi-function controller, the SK-3000 Gen 3 delivers crystal-clear water with minimal maintenance.

The included Smart Controller automates the fleece advancement while continuously monitoring system performance:
Play Button: Press and hold to manually advance the fleece roll.
Alarm Mute & Reset: Press for 1–2 seconds to silence audible alarms. Press and hold for 5–7 seconds (or disconnect power for 30 seconds) to perform a full system reset.
Normal Operation Indicator: Solid Blue LED indicates normal standby; flashing Blue LED indicates active motor rotation.
Filter Jam / Float Alarm: Flashing Red LED with intermittent audible alarm triggers if the float remains activated for more than 5 seconds. Automatic advance is disabled until reset.
Empty Roll Alarm: Alternating Blue/Red flashing LEDs with an audible alarm trigger if the float is not activated for 8 hours, signaling an empty fleece roll.
Installation Error: Flashing Red LED every 10 seconds indicates the float was not triggered within 48 hours of setup or reset.
Q: Can the ClariSea SK-3000 cause my sump to overflow if the fleece jams or runs out? A: No. The unit features an integrated fail-safe bypass channel. If the fleece roll jams or runs out completely, water harmlessly overflows over the internal baffle directly back into your sump.
Q: How long does a single fleece roll typically last? A: Roll lifespan depends on aquarium bioload, flow rate, and water clarity. On average, a standard roll lasts between 1.5 to 3 months under normal operating conditions.
Q: What is the optional Clean Roll Positioning Kit used for? A: The optional Clean Roll Positioning Kit allows you to adjust or relocate the clean roll mounting arm. This is ideal for tight sump spaces, cabinets with low vertical clearance, or installations where the unit sits low in the sump water to keep the clean roll dry.
