22:34Sponge Filter vs Hang-On-Back vs Canister: Which Filter Actually Keeps Your Tank Clean
Save referenceCuriosity Gap
Most fishkeepers run one of these three filters, so whichever you own, you want to know if it wins. The tanks are identical and empty, which makes it look like a fair test where only the filter changes. The question mark keeps the answer back.
Naming all three types lets owners of each find theirs, and 'Actually' hints that the popular answer might be wrong.
Asking WHICH CLEANS BEST boils the long title down to three words, and the plain labels over each tank let you tell the options apart without knowing the kit.
When you compare a few options, stage each one in an identical setting so the thing you're testing is the only difference. Label each plainly and ask the question as a short headline.
Change only the thing you're testing, and the test looks fair.
Apply this pattern to your next video.
Bring the reference into a packaging brief, then decide what your title and thumbnail should each communicate.
