This will allow the larger debris to be trapped before entering the tight weaved lower section of the pad. Q: What is the best way to use your FilterFirst filter pad and your 100 micron polishing pad together?A: Your aquarium water should flow first through the FilterFirst pad to remove small to large particles from the water, then through the polishing pad to remove fine particles. This layering method will increase the useful life of your polishing pad.Q: How often should I change my aquarium filter pad?A: Most hobbyists rinse the filter pad every two weeks and replace them monthly during a water change. The more often you change filter pads the better your water quality; filter pads remove organic solids before they have a chance to further break down.Q: I am using your Dual Density filter pad in my canister filter. What is the easiest way to make these shapes?A: Take your original filter pad which came with the canister filter and cut out a piece of card board the exact size and shape. Now put the cardboard on our FilterFirst roll, use a pair of scissors and cut around the cardboard template.Q: Would I need to remove FilterFirst filter pad from my filter when treating fish for Ich I Ick, as you do with the carbon filters?A: No, you do not need to remove our Premium filter pad when medicating your fish.

HIGH QUALITY AND DURABLE - Our polishing pad is constructed with interwoven polyester fibers making it strong and durable enough to even be cleaned in a washing machine. This pad’s consistent, the reliable design gives superior filtration. TIPS – To increase efficiency and extend the use of our polishing pad, have water flow through a pre-filter pad such as our FIlterFirst or ClassicBlue then through the polishing pad.   FREQUENTLY ASKED QUESTIONS: Q: Which side of your polishing pad should the water go through first?A: If both sides of the felt pad are soft to touch then water will flow equally through either side therefore, it does not matter which side goes up. However, if one side of the felt feels rough to touch, it has been treated to keep fibers from migrating or piling after cleaning. When using this felt pad, it is best for the water to flow through the soft felt side first.Q: Does the 50, 100, or 200-micron polishing pads trap the finer stuff from my aquarium water?A: The smaller number of microns, the smaller the holes in the polishing pad. In this case, the 50 microns will trap much finer particles than the 100 or 200 microns.Q: How often do you have to clean this filter pad?A: Our polishing pads trap very fine debris and can clog up as quickly as 24 hours of usage alone. To extend the life of your polishing pad, place it below a regular pad like our Classic Bonded pad where water flows through the Classic pad first, then the polishing pad can last up to 1 to 2 weeks before cleaning is required. Q: Should the polishing pad go over or under the regular filter pad?A: You want the water to flow through your regular filter pad first to trap larger particles before the water flows through the polishing pad. This will keep your pad lasts longer before it needs to be cleaned or replaced. Q: How do I clean the polishing pad?A: You can clean our polishing pad by rinsing it in fresh water, wringing it out, and repeating this process until the water runs clean. If you ever need to deep clean our polishing pads, they are durable enough to be cleaned in a washing machine.

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.
