I trust GC Tek’s sizing because they use real-world testing and not just theoretical numbers. One cubic foot of media handling 50 lbs of fish feed per day is a practical benchmark, not a sales pitch. Makes me feel confident about choosing the right filter for my pond.

I like their conservative approach. Even though the media can handle more, they size based on actual results. Shows they care more about performance than overselling.
