MAX-Nano Thin Mesh Filter 100 Micron by Red Sea

• Stage in Filtration: The 100 micron thin mesh bag is used after or instead of coarser mesh (or as an optional finer replacement) to “polish” water—i.e. remove fine suspended particles that remain after the bulk mechanical filtration. It’s typically not the only filter medium, but one stage in the chain.

• Flow Behavior: Because it is finer, it tends to clog more quickly than coarser bags (especially the 225 micron versions). As clogging increases, water flow through the bag will reduce, possibly leading to increased head loss, back pressure, or even bypass if the unit allows. Regular cleaning is required to maintain good performance.

• Effect on Water Clarity: It improves visual clarity, reduces visible suspended solids, and helps reduce organic load in the water column. This can help downstream filtration components (skimmers, bio-filtration) perform more efficiently.

Advantages

• Excellent polishing—good for mature, well-cycled aquaria where you want very clear water.

• Improves overall water quality by removing fine particulate organic matter, which might contribute to unwanted nutrient accumulation or cloudiness.

• Thin-mesh construction means easier cleaning and less “bulk” clogging (at least until loaded).

• Compatible with the MAX NANO system, so good fit and design integration (holders, sponges, etc.).

Limitations

• Faster clogging / more frequent cleaning required compared to coarser micron bags (e.g. 225 micron).

• Because it’s very fine, water flow restrictions can become an issue if the bag is not kept clean. This could stress pumps or reduce circulation in certain setups.

• Less capacity to trap larger debris; if used without a coarser prefilter, might overload or require too much maintenance.

• Thin mesh will not catch tiny dissolved organics, very fine colloids, or particles smaller than ~100 µm; for those, you’d need even finer filters or chemical/adsorptive media.

Recommended Usage of MAX-Nano Thin Mesh Filter 100 Micron 

• Use the 100 µm mesh bag after a coarser mesh (225 µm) or some mechanical prefilter to reduce bulk load, especially in new tanks or after disturbances/maintenance.

• Regular inspection of flow and water clarity; when you notice flow drop or obvious debris build-up, remove and rinse or swap with a clean one.

• When cleaning, avoid aggressive scrubbing—just gentle rinsing, possibly with aquarium water first to avoid shocking system with fresh water if there’s residue or trace elements in the bag.

• Keep a spare bag so you can rotate while one is being cleaned. That way you minimize downtime or bypass.

• Ensure correct installation in the filter bag holder so that all water is forced through the mesh (no bypass paths). Also ensure sponges or other buffer material around the bag are correctly positioned (if used) to prevent air pockets or flow irregularities. The MAX NANO manual shows the bag holder plus small sponges.
