How to choose filter socks and reactor parts
Extras must match your reactor model and the size of your filter system.
Mesh size
A 200 µm sock catches suspended dirt; a 500 µm bag holds filter media.
Change often
Wash or swap a filter sock every couple of days, or it starts adding nutrients itself.
Right model
Hoses, strainers and bypasses fit a specific reactor model – check it in the product name.

What is an air CO2 scrubber for?
It removes CO2 from the air going into the protein skimmer, which helps keep pH higher. It is most useful in a closed room.
Can a filter sock be washed?
Yes, it can be rinsed and machine-washed without detergent. Keep a spare so you can swap it quickly.

Marine equipment needs maintenance and spare parts over time. A worn hose or clogged strainer cuts the flow through a reactor, and a full filter sock lets dirt back into the system. The extras here keep the system running or extend it.
A filter sock is the simplest way to remove suspended dirt before it breaks down and loads the water. Keep a spare so a full sock can be swapped at once and washed later. A media bag holds carbon, phosphate remover or other media in one place, so it is easy to take out.
In a closed room the air is often rich in CO2, which pushes pH down. An air scrubber removes carbon dioxide from the air going into the skimmer and helps keep pH higher. When ordering a spare, check the reactor model in the product name; parts do not fit other models.
