KORALIA NANO vs PICO EVOMAG: Which Flow Pump Do You Need?

Quick answer

Choose the PICO EVOMAG if you want to aim flow precisely and keep the pump affordable. Choose the KORALIA NANO if you need controller-based interval programming and a compact, energy-saving design.

Flow direction: sphere joint vs fixed output

The PICO EVOMAG uses a sphere joint to adjust flow direction and control flow, so you can point output where livestock and corals need it. The KORALIA NANO's catalog entry does not list an adjustable nozzle, so plan its placement around a fixed flow path. If you rearrange rockwork or want to sweep detritus from a specific corner, the PICO EVOMAG gives you more flexibility without moving the pump body.

Control and scheduling: manual vs controller-ready

The KORALIA NANO can connect to a controller and be set to intervals of seconds, minutes, or hours, which suits aquarists who want pulsing or alternating flow patterns. The PICO EVOMAG's catalog facts do not mention controller compatibility, so treat it as a manually adjusted pump. If you already run a controller or plan to add one, the KORALIA NANO avoids a later upgrade; if you prefer set-and-forget flow, the PICO EVOMAG keeps things simple.

Mounting and positioning

Both pumps include a magnet-suction cup support for free positioning, so you can place either on the glass without a permanent bracket. The KORALIA NANO also includes a cable protector, which helps protect the cord from abrasion or accidental pulls. The PICO EVOMAG is described as suitable for use with a Rotating Water Deflector, an optional accessory that can broaden flow coverage if you want more dispersion.

Size, efficiency, and price trade-offs

The KORALIA NANO is described as compact and energy saving, which matters in small tanks where equipment bulk and running costs add up. The PICO EVOMAG has a lower catalog price, so it costs less upfront. Neither product record lists flow rate, wattage, or maximum tank size, so compare those specifications on the product pages before you buy if your tank is near the upper limit for either pump.

Decision rules: which pump fits your tank

• You want to aim flow precisely: Pick the PICO EVOMAG. Its sphere joint lets you direct flow and adjust output, which is useful when corals or plants sit in specific spots.
• You want timed flow patterns: Pick the KORALIA NANO. It connects to a controller and can run intervals of seconds, minutes, or hours, so you can vary circulation throughout the day.
• You are working to a tight budget: The PICO EVOMAG has the lower catalog price. If controller programming is not a priority, it covers basic circulation for less.
• You need specifications before deciding: Neither record lists flow rate, wattage, or tank-size rating. Check those figures on each product page and match them to your tank volume and livestock needs.

Product facts

• PICO EVOMAG: Sphere joint for adjustable flow direction and flow control. You can aim output at a specific area without repositioning the whole pump.

  

• KORALIA NANO: Can connect to a controller and be set to intervals of seconds, minutes, or hours. This lets you create timed flow patterns rather than a single constant stream.

  

Who each pump suits

Best for

• Aquarists who want directional flow control in a small tank
• Budget-conscious setups that do not need controller programming
• Tanks where a Rotating Water Deflector may be added later

Not for

• Aquarists who want scheduled interval flow without adding a separate controller
• Buyers who need published flow or wattage figures before choosing
