Modular Mechanical Fleece Roller Filtration

The Patent Pending Dropin D-4 fleece filter fits directly into most 4 inch filter sock chambers. The Dropin filter then automatically unrolls new material as it gets clogged, removing suspended particles from your aquarium and producing crystal clear water.  Enjoy maintenance-free aquarium filtration for months at a time.

The Dropin filter is a direct replacement for filter socks on sumps with sock trays. Simply remove your sock and insert the Dropin Filter.  As water passes through the Dropin filter and the filtering material becomes saturated with waste, the water level will begin to rise.  When water contacts the optical sensor, a motor is activated to advance clean filter material. As clean material is exposed, water is now able to flow freely, lowering the water level in the sock tray and deactivating the motor.

Dropin Filter main benefits:

  1. Results in crystal clear water filtered down to 50-microns — double the filtering capacity of most filter-socks.
  2. Waste is removed from the water column before it has time to breakdown, helping to maintain low nutrient levels.
  3. The constant chore of monitoring and swapping filter socks or other mechanical media every few days is eliminated for months at a time. Once the filtering media is exhausted, replacing the roll is very simple.
  4. Fitting the unit to a sump with filter socks requires no adjustment simply remove the sock and fit the unit, other mounting options are available for sumps without sock holders.
  5. Multiple units can be ran side by side and work in tandem.

Love this thing
Style: Data Transfer (10Gbps), Style: Data Transfer (10Gbps)
I’m really impressed with my Satechi power passthrough 4 port USB C Hub. It’s really slick, streamlined, and really good looking too. It works well, doesn’t get hot or even warm to the touch.

Works, but man it is SLOW
TL/DR review follows: This thing does what it claims to do (gives you 4 USB ports that you wouldn't have otherwise), but the data transfer speed of any SSD I connect through this Satechi Hub is half what it is when the SSD is connected via my OWC Hub (data transfer rate is double when connected via the OWC Hub vs. being connected via the Satechi Hub). I'll keep this Satechi gadget (in a drawer) for times when I really, really need more USB C ports and therefore will be more willing to tolerate the data transfer speed slowdown penalty. I cannot possibly consider this to be a primary data transfer pathway however. These above results are from an M1 Mac Mini with 16GB RAM and MacOS Monterey with speed measured by Blackmagic Disk Speed Test utility. I did not get similar results on my 11th Gen Intel Core i9-11900 processor PC running Windows 11. Data transfer rates are the same (SLOW) when any USB drive is connected directly to the PC USB C port or when connected via the Satechi Hub. Highly worth mentioning, though, is that all data transfer speeds on the PC are HALF the speed obtained on the Mac Mini when connected via my OWC Hub. All PC data transfer rates were measured by CrystalDiskMark utility One interesting anomaly worth mentioning is that the PC will not eject USB drives if they are connected directly to the single USB C port on the PC BUT it WILL eject any/all USB drives if they are connected via the Satechi Hub. This particular PC has never been able to eject USB devices correctly. The Mac Mini ejects all these same USB devices correctly no matter how they are connected. All USB drives are formatted Windows NTFS whether connected to the Mac Mini or the Windows PC (for those who care) Conclusion: An interesting experiment, but for me the Satechi Hub is not worth what I paid for it. I can easily see it being a worthwhile investment for many, assuming undemanding use cases, however

Fantastic, stylish, and easy shoes!
Size: 2.5 Little Kid, Color: Aqua/Multi
My daughter LOVES these and wears them daily. She says they're really comfy and they slip on easily. They've held up for several months of daily wear so far and are still going strong!
