Conquer Heavy Waste with a 25mm Aquarium Pre-Filter
Keeping monster fish like Oscars or giant Plecos? Transform your tank maintenance with our custom-engineered 25mm aquarium pre-filter. We designed this Monster Edition magnetic fish toilet specifically for extreme bioloads.
Perfectly Matches 1-Inch (25mm) Plumbing
Standard pre-filters restrict water flow and overwork high-end pumps. We built this Monster Edition exclusively for 1-inch (25mm) tubing. It seamlessly connects to massive canister filters like the Fluval FX4 and FX6 with zero bottlenecks. This 25mm aquarium pre-filter extracts heavy organic waste before it ever clogs your delicate biological media.
Instant 3-Second Cleaning
Stop wasting weekends tearing down massive canister filters. By installing this Monster Edition unit, you solve this instantly. Simply slide the outer magnetic ring to flush the collected sludge. Purge days of thick, stringy Pleco waste in just 3 seconds—without getting your hands wet or turning off your main pump.

1″ kit is the same kit only you are supposed to connect the pipe with no adapter. The flow isn’t enough to feed an FX6 so I will be ordering a second one. Great product otherwise, just don’t expect an FX6 to get enough intake from one.

Got it in about 8 days. Works perfectly for my big tank.

Finally solved the flow rate drop on my Fluval FX6. My massive Pleco creates so much waste that my canister media was clogging weekly, but this 25mm pre-filter handles the bioload with ease. The wide-mouth design maintains full suction and the magnetic cleaning feature is a total game-changer for quick maintenance without getting my arms wet.

Overall, a fantastic addition to my custom filtration system. I ordered this because my old pre-filter kept clogging and couldn’t handle the high flow rate. Shipping to the US took 11 days, which is perfectly fine for specialty gear. The larger pipe diameter is exactly what I needed—water flows through it smoothly without bottlenecking. You can tell the design is focused on maximizing water volume rather than just making the walls thicker. It traps debris like a champ and keeps my main tank crystal clear. Very satisfied with the purchase and the build quality!

The larger pipe diameter makes a huge difference in the flow rate. No clogging issues so far.
Chris –
Love the larger pipe diameter! Flow rate is excellent.
Danny –
Plumbed this into my existing setup this weekend. I love that it connects directly to standard 1-inch PVC lines without needing any crazy cut modifications or extra adapters. The upgraded 1.0mm heavy-duty mesh is perfect—it stops the big solids from my Oscars but doesn’t clog up instantly. The magnetic flush is super smooth.
Renee Johnson –
Solid construction and the stainless steel mesh is much better than the cheap foam sponges that collapse under high pressure. It took me a few minutes to plumb it into my 1-inch lines, but the unrestricted water flow makes it worth the effort. My water clarity has improved noticeably since I started catching the heavy waste early.

Finally a pre-filter built for real monster bioloads! The larger diameter lets the water rip through while the magnet traps the heavy sludge perfectly. A massive time saver.

I was upgrading my plumbing and had a question about whether the 25mm Monster Edition needed extra filter floss inside to work properly. Emailed their support and got a reply in like 2 hours. They clarified that the heavy-duty stainless steel mesh is all you need for the primary filtration so it doesn’t restrict the massive flow. Hooked it up yesterday and it handles my high-flow pump easily. Great customer service and engineering.
