When it comes to high-performance nano aquascaping, managing a small volume of water requires precision, reliability, and efficient filtration. At AquascapeGuide, we designed two distinct compact filtration powerhouses to keep your miniature underwater worlds pristine.
While both filters are designed for small footprints, they serve very different roles depending on your tank size, layout, and how much you love to customize your gear.
Let’s break down the ASG Nano Gen2 and the all-new ASG PURE Mini so you can choose the exact right fit for your next aquascape.
The ASG Nano Gen2: The Battle-Tested, Ultra-Customizable Classic
If you love fine-tuning every single detail of your setup, the ASG Nano Gen2 is your dream filter. Standing at just 6 inches tall, this compact workhorse is a battle-tested, highly repairable classic that has been curated and perfected over time with a wealth of custom modifications.
Why the ASG Nano Gen2 Shines:
Ultimate Flow Control: Equipped with a 4-speed variable pump, it allows you to dial in the perfect turnover rate. This makes it incredibly versatile for ultra-small setups ranging from 2 to 8 gallons.
Unmatched Customization: You get to choose your style. Pick between three different versions of premium glass lily pipes, or opt for a sleek stainless steel set. You can even add our custom 3D-printed lily pipe holders to keep your rimless look perfectly dialed in.
Ready to Plug & Play: Out of the box, it includes a vibration-dampening mat, two 14-inch sections of tubing, and comes pre-loaded with filter media (coarse pre-filter, bio-media, filter floss, and custom 3D-printed spacers).
The Verdict: Perfect for bookshelves, tight spaces, and aquascapers who want variable flow control and extensive aesthetic options for smaller nano tanks.
The ASG PURE Mini: The Sleek, Next-Generation Future
The all-new ASG PURE Mini represents the next generation of the AquascapeGuide filter lineup. Standing at 8.5 inches tall, this premium stainless steel canister is built for aquascapers who want an elegant, minimalist, and powerful "plug-and-play" solution.
Why the ASG PURE Mini Shines:
Designed for Larger Nano Layouts: Featuring a robust, single-speed pump, the PURE Mini is optimized specifically to provide flawless circulation and turnover for 8 to 10-gallon aquariums.
Premium Stainless Steel Build: No plastic clunkiness here. The PURE Mini features a gorgeous stainless steel canister body and comes standard with its own matching stainless steel inlet and outlet lily pipes for a seamless, high-end look.
The Ultimate Blank Canvas: The PURE Mini comes with two internal partition trays and zero pre-packed media. Why? Because high-end aquascapes often require specific biological parameters. This design gives you a completely blank canvas to curate your own advanced media layout.
💡 Pro Tip: To maximize the biological filtration capacity of your PURE Mini, we highly recommend packing it with premium Seachem Matrix Bio-Media, which fits perfectly within the internal partition trays.
The Verdict: The future of the ASG lineup. It’s a sleek, simplified, premium stainless steel powerhouse designed for gorgeous 8-10 gallon layouts.
