Superfish 浮動清潔磁鐵

I was skeptical about the floating design, but it really does stay at the surface instead of sinking to the bottom. The magnet is strong enough to scrub through stubborn algae without scratching the glass.

The floating feature is a game changer—no more dunking my arm in to retrieve a dropped scraper, and the magnet holds strong enough that I don't even have to worry about it drifting away mid-clean. Glass is spotless in a couple of passes, and I've actually started looking forward to tank maintenance.

This little magnet handles the algae on my glass perfectly without me ever having to stick my hands in the tank. It floats, so even if I drop it, I don't have to go fishing for it in the gravel.
