You are essentially running a sponge filter with power head. That's why.The intake sponges on my HOBs do get clogged rather quickly, but on the other hand it keeps the bio media inside the bins cleaner, and it keeps the shrimp out of my pump
If you use high porosity foam, it will last longer. This is how AC style HOB can get away with high power pump, but makes bad mechanical filtration by letting fine pass through, and over shooting if biological filtration is the goal.
That made you a fish keeper, where fish is the focus. Plant focus folks place scape first, display few and small fish, and try to hide all equipment. They favor rimless tanks to blend in, as even rims are distracting.I get it about the Natural folks. Not a requirement for me. I use sponges in every tank, except where I have moved them into a sump. One tank has 2 HOBs but still gets a sponge, and 2 intake sponges. 4 of my 5 largest tanks have sumps,and the 5th has HOB + sponge in tank.
I keep 8 aquariums because they are lovely, even with filters, but fish health comes way before asthestic concerns.
My fish are the show here and I plant tanks, but some fish won't cooperate. Plants give the fish cover, often food, and they clean the water.
The illusion of another little world without plumbing is nice, but if you step back, it's still a big box inside your house. Hopefully you have nice fish in it!
