Watch how our Magnetic Aquarium Pre-Filter (The Magnetic Fish Toilet™) completely automates your tank cleaning in just 3 seconds!
Are you tired of constantly cleaning your messy canister filter? First of all, this innovative device offers the perfect solution for your tank maintenance. Because fish waste accumulates rapidly, you need a reliable system to keep the water crystal clear. Therefore, we designed this waste extractor to trap heavy debris before it reaches your main biological media.
Core Benefits of Our Magnetic Aquarium Pre-Filter
Essentially, this system uses magnetic technology to trap and isolate fish poop and uneaten food. As a result, you get a clog-free experience and visibly crystal-clear water.
- 3-Second Waste Separation: Indeed, it eliminates the need for manual scooping. Instead, you simply slide the external magnet to drain the trapped waste instantly, cutting 30 minutes off your weekly cleaning routine.
- Reduces Main Filter Load: Furthermore, by acting as a powerful inline filter, it prevents your expensive canister filter pads from clogging. Consequently, you will perform fewer messy filter cleanings and save money on replacement media.
- Hassle-Free Setup: Best of all, it is universally compatible! In addition, it fits most standard fish tank hoses (16/18/20mm). Similarly, Model A installs easily via suction cups, while Model B connects directly inline for a seamless, hidden look inside your cabinet.

Love the minimalist look. The Model A suction cup mount is clean and unobtrusive. Does its job silently and incredibly well. My water has never been this clear with so little effort. Smartest purchase this year.

Been a sorta new tropical fish keeper for about 6 months now, and I grabbed this fish toilet pre-filter for my 55-gallon tank—setup could not have been easier. Just pressed the suction cups against the tank wall and they stuck solid, hooked it right up to the 18mm tube on my canister filter, and wrapped it up in 5 minutes flat. No tools, no taking parts apart—even if you’re totally clumsy with this stuff, you can pull this off.
It’s only been 3 days—though let’s be real, most canister filters don’t clog up that fast anyway. Here’s the actual win, though: the bigger bits of fish waste and leftover food (the stuff that’d pile up right before my filter’s cartridge and gum it up by day 5) are now getting trapped in this pre-filter’s collection chamber. I can see those chunks piling up in there every day, and cleaning it’s no hassle—no tearing things apart, just slide it open and done. Gonna test if that “3-second clean” claim’s actually legit this weekend.
Locking in 5 stars for now! Gonna check back in after a week to talk about how it handles steady gunk buildup—so far, this $42 pick’s totally worth it!

At first, I thought the price was a bit steep, but after using it for two months, it’s totally worth every penny. I save 30 minutes every week on tank cleaning, and I’ve cut down a lot on filter pad replacements and water change costs. It basically pays for itself in just a few months! My only small suggestion is that it would be even better if they included an extra pipe sealing cord.

Been using this in my tank with lots of fish for a few weeks. Setup is simple, it cleans fast, works great with my canister filter, and cuts down maintenance time a lot.I just have to drain the waste more regularly since my tank is heavily stocked, but it’s absolutely worth it and a solid pick for aquarium care.

I was on the fence about this at first, but after a week of using it in my tank, I can honestly say it’s worth way more than I paid for it. Super happy with my purchase!
