Works like it says. Clears your water and filters great.

I have used many other filter pads in my reef aquarium, and these are the best by far! I have used blue, green, and red filter pads they all worked about the same. When I bought these, I assumed it was just going to be the same thing as well. I mostly bought them because I figured it might be better to use a filter pad that did not have any color dye. Wow, was I mistaken, these pads are way better. There are two layers, and the layers are different, one side is made to catch larger particles, and the other one is made to captures finer particles. You want the tighter weaved section on the bottom if not it will clog quickly and defeat the purpose of the pads. The pads last longer, during the standard period which it would require me to replace the pad, these pads are not even halfway utilized. My unfiltered water comes in from one side on my Nano tank and then runs over the pads. So now instead of replacing the pad once a week, my process is replacing the pad, then next week rotate the pad and then the following week replace the filter pad. I could even go longer than a week between the process how when I replace the filter pad, there is still a large section in the center that is clean. I have been using the pads now for about a month, I could not imagine a month ago claiming that I suggested a filter pad for anyone in the aquarium hobby how I felt like they all worked the same, but these filter pads are great, and I would highly recommend them. While I gave the five starts for easy to clean, I do not clean these pads. They are cheap enough that I can toss them when they are done. I mostly gave them five stars on this one because I was just amazed at how good the pads work.

Works great for rainwater harvesting filter.

I have aqueon hang-on-back filters on my 75 gallon tanks. This filter product lets me cut filter pads that are much cheaper initially than those sold by the manufacturer. The fact that they are washable and reusable adds to the economy. And they work!

I buy a roll a few times a year, cut it up in rectangles and use it along with other foam media in my hang on filters. It can also be used around an intake filter for odd ends. They go in white and come out brown. Because of the low price I usually throw out the rectangle and replace it instead of rinsing and reusing. It helps keep the other foam media from building up as well. Before I found this, I spent a lot more money buying other things that the pet store tells you to buy which don’t last as long.

I cut the filter to match my filter device and works great. My aquaria are heavy planted, and with natural wood, plush fish and snails so theres a lot to filter. I rinse the filter pads (weekly) and use them for 2 - 4 weeks depending on load. The water flow may be reduced before water getting cloudy or dirty looking. The filter rinses very nicely, doesnt lose structure as other filters when rinsing for reuse.

For clear fish pond water

It takes a lot of time cutting it to shape and size of filter and in the end it doesnt make a difference, Ive been in this hobby for 10 years and I bought this once and I will never buy it again

Works perfect.

I cut out sizes for my caddy in my Nuvo 60 gal. Got around 8 or 10 out of one sheet. Absorbs very well catching the bigger particles on the more open rougher side than straining through the finer side of the pad. What is nice is that you can easily wash the pad and reuse. Washes out easily under a kitchen faucet. I try to change out pads daily. I am set for a long time with this purchase.
