After I left my aquarium store I started designing one. I went back and forth testing, went to some factories, and finally developed the ultimate pad called our premium dual density filter pad.
What makes this one so special is it has dual layers to it. It has a top layer which is an open weave to trap large and medium sized particles and then we created a dense network of fibers down at the bottom and this traps fine particles. So as water flows through the top layer of the filter pad, plant leaves and uneaten fish food gets trapped in this side. The smaller particles are trapped in the dense bottom layer of the filter pad to ensure pure water.
If we turned the pad upside down and run the water through the bottom layer first what would happen is because the filter pad is so fine, it will trap large medium and fine particles the filter pad would clog up very rapidly.
So, when we developed this system it worked very well. This filter pad is very durable you can rinse it several times and reuse it or you can replace it. It is available in a six-foot, twelve foot, twenty-four foot size or even eighteen inches long for the wider filtration systems. The premium dual density filter pad will work in wet dry filters, sumps to, bio ball filters, canister filters and hang on the back filtration.
