  • How does GC Tek size bead filters?
  • How do we know how much bio conversion can be accomplished with a bead filter?
  • Is there a standard to go by, or do we just take a look at the competition and then add a few points in our favor?

This is how!

University tests have shown that a cubic foot of beads that have 400 - 450 cu. ft. of surface area will handle 50 lbs. of fish being fed 1% body weight per day @ 38% protein.

This is the formula that we use, even though our beads have 500 to 550 sq. ft. of surface area per cu. ft. and in theory should do more, we refuse to stretch or make claims beyond what has truly been tested.

GC Tek's AlphaONE filters are known for their superior filtration efficiency and low energy consumption. The company has developed a unique formula to size its filters, ensuring each filter is optimized for its specific application.

The Science Behind GC Tek's Sizing Formula!

The primary function of a biological filter is to provide a large surface area for beneficial bacteria to colonize. These bacteria break down organic waste and convert it into less harmful compounds. The more surface area available, the more bacteria can grow, and the more waste can be processed.

Why Choose GC Tek's AlphaONE Filters?

GC Tek's AlphaONE filters are designed to be the most energy-efficient filters on the market. The filters feature more than double the lateral surface area of other filters thanks to proprietary Omnifuser technology. This design allows for better water oxygenation and provides a larger surface area for beneficial bacteria to grow.
Additionally, the AlphaONE filters come with the highest flow multiport valve on the market, which reduces energy costs by allowing for a smaller, more efficient pump. This feature alone can save the end-user hundreds of dollars annually in energy costs.
