These Popular Fish Tank Products Are Completely Useless

The aquarium hobby is packed with overpriced products, misleading marketing, and straight-up scams—and beginners are the ones paying the price. In this video, we break down 15 aquarium products that are a complete waste of money, don’t work as advertised, or actively make fishkeeping harder than it needs to be.

After 25+ years of keeping fish, making mistakes, and wasting thousands of dollars on junk gear, I’m calling out the worst aquarium products sold by pet stores and big brands—from bottled aquarium water and betta beads to feeder blocks, disposable filter cartridges, chemical algae killers, and more.

This video isn’t about being cheap—it’s about keeping fish healthy without falling for aquarium industry hype. Many of these products are marketed as “essential” for beginners, but in reality they cause unstable tanks, water quality issues, stressed fish, and unnecessary frustration.

If you’re new to fishkeeping—or tired of being upsold at the fish store—this video will help you:

Avoid common aquarium beginner mistakes

Save money on unnecessary aquarium products

Build a healthier, simpler fish tank

Spot pet store aquarium scams before you buy

Fishkeeping does NOT require a chemistry degree or a second mortgage. You need good fundamentals—not $20 rocks and magic bottles.
