Filter Bags for Aquarium Filtration
Maintaining pristine water quality is paramount for any aquarium or aquaculture environment, whether it's a small home setup or a large-scale commercial operation. Liquid filter bags play a vital role in maintaining water quality within these applications, where the health and well-being of aquatic life depends on consistently clean and clear water.
At Filterbag.com, we understand the unique filtration needs of aquarium water and we’re here to guide you in selecting the right filter bags for your specific application.
POG or PES Felt is the most common media for aquarium bag filters
Our aquarium customers consistently find that either polypropylene glazed (POG) or polyester singed (PES) felt all-welded filter bags offer an effective and reliable mechanical filtration solution. The filter media’s glazed or singed surface treatment prevents downstream fiber shedding, and all-welded filter bag construction eliminates contaminant bypass and provides an exceptionally strong bond for long service life. A nominal 100 micron rating strikes a good balance between capturing debris and maintaining adequate water flow, although it is common to find a range of 25-to-200-nominal micron ratings in aquarium applications.
POG and PES felts are valued for their durability and cost-effectiveness. POG and PES felt bags provide a robust solution for small and large aquariums in both freshwater and saltwater applications.
Addressing common aquarium filtration questions:
1. Why Do I See Bubbles After Replacing My Filter Bag?
If you notice bubbles in your aquarium after installing filter bags, don't be alarmed. The presence of bubbles after replacing aquarium filters is often caused by the release of trapped air in the filter media. Bubbles can be minimized by pre-washing your filter bag. Simply rinse the bag thoroughly with fresh, clean water three times before installation.
2. Why is a range of different micron ratings recommended for filter bags?
This is a common point of confusion. Here's a breakdown:
- Nominal vs. absolute ratings: POG and PES felt bags are typically nominally rated, meaning they capture particles of the specified micron size approximately 50% to 80% of the time.
- Absolute-rated bags, such as those made from nylon monofilament (NMO), provide more precise filtration, capturing 90+% of particles at the specified micron rating.
- Individual aquarium needs: The ideal micron rating varies depending on the specific conditions of your aquarium. Generally, a range of 25-200 microns is suitable for most applications.
3. How do I choose the right filter bag?
When selecting a filter bag, consider:
Aquarium size and inhabitants: Larger aquariums and those with more inhabitants may require more frequent filter changes or higher micron ratings.
Type of debris: If you're dealing with fine particles, a lower micron rating might be necessary.
Flow rate: Ensure the filter bag allows for adequate water flow to maintain proper circulation.
