Upgrade to Hands-Free, Ultra-Clean Aquarium Water

Replacing dirty, smelly filter socks every few days is one of the most tedious chores in reef keeping. The D-D ClariSea SK-5000 Automatic Fleece Filter eliminates filter socks entirely, replacing them with a continuous roller filter that keeps your water polished and your nutrient levels under control automatically.

Engineered specifically for high-turnover marine reef tanks and large freshwater setups, the ClariSea SK-5000 suspended fleece unit mounts directly into your sump. Water flows from your display tank through a high-efficiency fleece roll that traps detritus, floating waste, and organic particles down to the micron level. As the media clogs, the smart motor automatically rolls fresh fleece into place—giving you weeks of hands-free mechanical filtration.

The Science of Continuous Waste Removal

Understanding how the ClariSea SK-5000 removes organic waste helps explain why it drastically improves water quality compared to traditional filter socks or poly-filter pads.

1. Direct Waste Trapping

Water draining from your aquarium enters the ClariSea body and passes through a fine, non-woven fleece layer. This barrier captures fish waste, uneaten food, and particulate before it can settle in your sump or pass into your protein skimmer.

2. Automatic Water-Level Sensing

As organic debris accumulates on the submerged fleece, water resistance increases, causing the water level inside the ClariSea unit to rise. When it reaches a preset height, a floating sensor triggers the smart motor controller.

3. Motorized Media Advance

The controller activates the motor to wind up a small section of dirty fleece onto the take-up spool while drawing fresh fleece into the water path. The water level drops immediately, and the system resets itself automatically until the next advance cycle.

Why the ClariSea SK-5000 Outperforms Traditional Filter Socks

If you still clean filter socks by hand or run them through the washing machine, switching to an automatic roller filter completely changes your maintenance routine.

• Nutrient Control Before Breakdown: Filter socks trap waste, but that waste remains submerged in high flow—constantly rotting and releasing nitrates ($NO_3$) and phosphates ($PO_4$) into your system. The ClariSea advances dirty fleece out of the water path, locking waste away before it can decompose.

• Consistent Water Flow: Filter socks clog rapidly, causing sump water levels to fluctuate and protein skimmers to overflow. The ClariSea maintains steady backpressure and consistent water levels in your sump.

• Massive Labor Savings: Instead of washing dirty filter socks every 2 to 3 days, a single 40-meter ClariSea fleece roll typically lasts several weeks to months depending on bio-load.

• Cleaner Sump & Equipment: By removing detritus at the entry point, your sump stays free of sludge, protecting your return pumps, skimmers, and reactors from debris buildup.

Technical Specifications and Dimensions

Ensuring proper fit inside your sump skimmer chamber or drain section is key before installation. The SK-5000 features a compact footprint designed to maximize flow while minimizing sump footprint.

Pro Tip: Measure your sump’s drain chamber depth and height clearance before mounting. The ClariSea SK-5000 can be hung directly onto sump glass walls or positioned on a flat sump floor using its adjustable mounting bracket.

Key Benefits for Marine Reefs and Planted Aquariums

Installing a ClariSea SK-5000 delivers noticeable long-term benefits for coral health, clarity, and biological balance.

Enhances Coral Growth & PAR Penetration

By continuously stripping microscopic particles from the water column, light from your LED or T5 fixtures penetrates deeper into the display tank with less scattering. Zooxanthellae algae inside your SPS and LPS corals receive higher light levels (PAR), promoting faster growth rates and vivid coral pigmentation.

Extends Protein Skimmer Lifespan

Because the ClariSea removes heavy solids before water enters the skimmer chamber, your protein skimmer doesn’t have to work as hard. The skimmer collection cup fills with finer organic compounds rather than thick mud, reducing skimmer maintenance.

Built-In Safety Alarms

The smart controller includes fail-safe features to protect your system:

• Fleece End Alarm: Alerts you when the fleece roll is completely empty.

• Motor Fault Alarm: Automatically cuts power to the drive motor if a physical jam or snag occurs.

• Over-Roll Protection: Prevents unnecessary roll advancement if water levels remain elevated due to downstream sump restrictions.

Step-by-Step Installation Guide

Setting up your ClariSea SK-5000 takes about 30 to 45 minutes. Follow these simple steps for a seamless installation:

1. Assemble the Acrylic Frame: Follow the included quick-assembly manual to slot the main body panels, drive reels, and fleece guide rollers into position.

2. Mount in the Sump: Hang the unit on your sump wall or place it on the sump floor in your primary drain section. Adjust the hanging bracket height so the water outlet sits partially submerged (between 10 cm and 20 cm water depth).

3. Plumb the Water Drain: Connect your display tank’s primary drain pipe to the 32mm (1″) ClariSea inlet connection using rigid PVC pipe or flexible hose.

4. Thread the Fleece Roll: Slide a fresh 40-meter ClariSea fleece roll onto the supply spool. Route the fleece down through the main body guides, across the lower rollers, and wrap the leading edge securely onto the motorized take-up spool.

5. Connect Controller and Power: Plug the float switch and motor cable into the smart controller. Connect the power adapter to a wall outlet and verify manual advancement by pressing the feed button on the controller.

Frequently Asked Questions

How long does a single fleece roll last on the ClariSea SK-5000?

Roll lifespan depends heavily on your aquarium’s bio-load, feeding frequency, and water flow rate. On a well-established 100-gallon reef tank with moderate fish stocking, a standard 40-meter roll typically lasts 4 to 8 weeks. Newly installed tanks or heavy feeding setups may consume the first roll faster as the unit strips out accumulated detritus.

Is the fleece material safe for sensitive corals and invertebrates?

Yes. ClariSea replacement fleece is made from 100% phosphate-free, non-woven, aquarium-safe synthetic material. It will not leach silicates, heavy metals, or binding agents into your reef water.

Can I run the ClariSea SK-5000 on a freshwater aquarium?

Absolutely. While designed with saltwater reef sumps in mind, the SK-5000 performs exceptionally well on large freshwater planted tanks, African Cichlid setups, and Monster Fish aquariums where mechanical waste production is high.

What happens when the fleece roll runs out?

When the fleece roll reaches its end, the smart controller detects that the roll is no longer advancing properly or that water is overflowing the safety bypass. The controller emits an audible alarm and stops the motor to prevent gear wear until you install a fresh roll.

Can I bypass the filter if I am dosing liquid coral foods or medications?

Yes. The ClariSea body features an easily accessible manual bypass slider. Opening the bypass allows water to flow around the fleece element without advancing the roll—ideal when dosing plankton, liquid reef feeds, or specialized water treatments.
