How GC Tek Sizes Our Bead Filters

  • 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.
