Our Experience I owned an aquarium store (and separate aquarium maintenance company) for over 25 years during which I spent a lot of time and resources searching out and testing countless filter socks to find the best for my clients. Fortunately, one stood above the rest giving consistent and repeatable filtration performance in all types of aquariums. These long-lasting heavy-duty filter socks are the best the industry has to offer!   FILTER SOCKS FAQQ: Is the 100 micron or 200 micron better for my aquarium?A: The lower the micron rating, the more floating debris it removes hence the filter socks clog up faster. Many hobbyists have both the 100 and 200 micron filter socks which allow them to swap out their 200-micron socks from time to time.Q: How often should I change the filter socks?A: It depends on the tank load, but generally you want to change your filter socks once a week or every two weeks. The more often you change your filter socks, the better your water quality; it removes organic solids before they have a chance to further break down.Q: Is it better to use a longer sock with more socks hanging in the filtered water than a shorter one?A: Ideally the filter sock should be hanging in the water without touching or laying on the bottom of the sump. If a shorter sock is above the water line there may be more noise as water drains from the sock side and splashes into the water In your sump.Q: Is there a glaze finish on these filter socks? the glaze makes them less flexible and stiffer. or are they untreated?A: Our socks are untreated.

Our filter sock material is thick and our plastic ring is slightly too large to drop through the hole in the shelf.Q: What makes Aquatic Experts felt filter socks better than any other brand?A: Owning an aquarium store and service company for 25 years meant that we had to test countless filter socks to find the best ones.
