Uniclife 64 GPH Aquarium Air Pump with Dual Outlets Adjustable Quiet Fish Tank Air Pump with Air Stone Airline Tubing Check Valve and Connector Accessories for 10-100 Gallon Fish Tank

Setting up a new air pump is one of those chores aquarists learn to do quickly, but living with it is where the real verdict forms. After six weeks of continuous use, the Uniclife air pump has earned a spot in my rotation as a quiet, capable, and unusually complete kit for small to mid-sized setups—and a serviceable backup for larger tanks.

What I tested and how I used it

I ran the pump on three configurations:
- A 10-gallon shrimp tank using a single included air stone.
- A 20-gallon community tank with one outlet powering a sponge filter and the other running an air stone.
- A 75-gallon planted tank where both outlets fed a pair of medium air stones set at mid-depth for surface agitation.

In all three setups, the pump ran 24/7. I mounted it on a flat shelf above the waterline with the included check valves installed in-line to prevent backflow during power loss.

Design and setup

The pump is compact and light with two rubberized feet that do a good job of decoupling vibration from the surface. Two barbed outlets on the front and a rotary knob on the back keep the layout simple. The knob adjusts total output; there’s no per-outlet control, so both lines increase or decrease together.

The kit is generous for the price: two blue air stones, about 6.5 feet of airline tubing, two check valves, and plastic connectors. For a basic aeration setup, you don’t need to buy anything else to get started. Just note:
- The airline length is enough for small to medium tanks placed near the pump. If your tank sits in a cabinet or you need longer routing, plan on extra tubing.
- There are no suction clips for cable management; I added a few to keep the lines tidy.
- As with any porous stone, rinse the air stones thoroughly before use to remove dust.

Setup took me 10 minutes: cut the airline into two lengths, add a check valve to each (arrow pointing toward the tank), push on the stones, and plug the lines onto the outlets. The barbs hold well; I didn’t need clamps.

Performance and noise

Uniclife rates the pump at up to 64 GPH airflow, 0.016 MPa pressure, and 4 W power draw. In practice, it’s appropriately strong for two moderate loads rather than multiple deep or restrictive devices. Here’s what I observed:

• 10-gallon: On the lowest third of the dial, the air stone produced a steady column of fine-to-medium bubbles with excellent surface ripple. I eventually had to turn it down further to keep the shrimp from surfing the current.
• 20-gallon with sponge filter + stone: The pump comfortably powered both without starving the filter. Adjusting the dial let me fine-tune the balance between the sponge lift and the aesthetic bubbles. I would have loved independent outlets, but a simple inline valve on one line solved it.
• 75-gallon: With two stones placed around 16–18 inches deep, the agitation at the surface was meaningful but not dramatic. It’s enough to improve gas exchange alongside a primary filter, but it won’t replace a dedicated high-output air pump for large, heavily stocked tanks.

Noise is where this model shines. On low to medium settings, it’s near-silent in a quiet room; at full output it produces a soft hum comparable to a refrigerator several feet away. Most of the audible sound in my setups came from the bubbles breaking the surface, not the pump itself. Placement matters:
- Set it on a flat, stable surface. On a thin metal shelf I heard more resonance; a mousepad or foam coaster eliminated it.
- Ensure the airline isn’t taut against furniture, which can transmit vibration.

Uniclife’s 25–45 dB claim tracks with my experience—practically inaudible on low, a gentle background hum on high.

Airflow and capacity

The headline 64 GPH rating is useful context, but what matters is how it handles real backpressure. The pump pushed air reliably to mid-depth in my 75-gallon and had headroom to run a sponge filter and stone in a 20-gallon. It’s less happy when split multiple ways beyond its two outlets. If you’re tempted to run three or four stones using T-connectors, expect the bubble output to thin out unless your stones are shallow and porous.

A few tips to get the most from it:
- Use one device per outlet whenever possible. If you must split, keep lines equal length and minimize depth to reduce backpressure.
- Pre-soak new air stones and replace them periodically; clogged stones make even good pumps look weak.
- There’s a small intake filter (cotton/foam) behind the housing grill. If output drops over time, check and replace or rinse this piece—airflow improved noticeably after I did.

Power draw and cost of ownership

At 4 W, this is a very inexpensive pump to run. Continuous operation for a year is roughly 35 kWh. At $0.15 per kWh, that’s about $5.25 annually. It runs cool to the touch; even after weeks of continuous use, the housing was warm but never hot.

Included accessories: good, with caveats

The out-of-box experience is excellent for beginners: you get everything you need to aerate a tank right away. Quality is mostly solid, but I’d flag a couple of small caveats:
- The airline is soft and easy to route, but the length may be limiting for cabinet runs.
- The included check valves worked fine, but inspect them before installation; I swap to my preferred brand for long-term setups.
- The air stones produce a dense bubble field; as with most budget stones, give them a thorough rinse to remove residual grit before dropping them in.

What I liked

• Quiet operation across the range; practically silent on low and tolerable on high
• Enough pressure to run a sponge filter and an airstone simultaneously
• Dual outlets with simple, responsive control
• Thoughtful anti-vibration feet minimize hum on hard surfaces
• Low power consumption and cool running
• Complete starter kit reduces extra purchases

What could be better

• No independent control per outlet; inline valves are a cheap workaround but add clutter
• Airline length is short for some placements
• No suction clips included for hose management
• Accessory quality is decent but not premium; I treat the stones and check valves as starters, not forever parts

Who it’s for

• Beginners setting up a first tank who want a quiet, all-in-one kit that just works
• Keepers running sponge filters in 10–40 gallon tanks
• Hobbyists who need secondary aeration in 55–100 gallon systems alongside a primary filter
• Shrimp, betta, and community setups where noise matters and airflow needs are modest to moderate

If your main goal is to drive multiple deep airstones in a 75–125 gallon tank, or to run several air-driven devices at significant depth, a higher-output pump with independent outlets will suit you better. For most day-to-day aquaria, this unit hits a sweet spot.

The bottom line

The Uniclife air pump is a quiet, efficient, no-fuss performer with enough muscle for two moderate air loads and the manners to live in a living room. The dual outlets and included accessories make it easy to get up and running, and the rotary dial gives you practical control—even if you’ll want inline valves for per-line tuning. After weeks of continuous operation, it hasn’t skipped a beat, and the noise profile is among the best I’ve used at this price.

Recommendation: I recommend this pump for small to mid-sized aquariums, sponge-filtered setups, and as supplemental aeration in larger tanks. It offers strong value, low noise, and low running costs. Just budget for a couple of extra valves, longer airline if needed, and consider upgrading the stones and check valves over time. For the price and performance, it’s an easy addition to a home aquarium toolkit.
