We found that a circulation pump with adjustable flow and low heat transfer provides the best balance for fish and coral health, with the Hydor Koralia Nano 425 leading in versatility.
The Options
Types Explained
Powerheads
Compact pumps that attach inside the tank, providing directed flow. Ideal for smaller tanks or spot circulation.
Circulation Pumps
Designed for high flow with wide dispersal, often used in reef tanks to simulate ocean currents.
Wave Makers
Programmable pumps that create alternating flow patterns, mimicking natural wave action for coral health.
Inline Pumps
Placed outside the tank in the sump or plumbing, these pumps are powerful and reduce clutter inside the display.

Before You Buy
Key Buying Factors
01
Flow for the tank
Match the flow to your tank and its inhabitants, since reef tanks need strong turnover while calm-water fish need gentler flow. Aim to eliminate dead spots without creating a torrent.
02
Controllability
Adjustable or controllable pumps let you tune flow and create wave patterns, which is valuable in reef tanks. Controllable wavemakers give more natural, varied water movement.
03
Reef versus freshwater
Reef tanks generally need much higher turnover than freshwater, so match the pump to your tank type and corals. SPS reefs want high, varied flow, while planted tanks need gentler movement.
04
Placement
Position pumps to spread flow across the whole tank and lift detritus off the substrate for filtration to catch, avoiding blasting corals or plants directly. Good placement makes the flow effective.
05
Safety and reliability
A well-made pump with a secure mount and safe low-voltage design runs reliably without coming loose. Reliability matters, since water movement is essential to the tank health.
Living With It
Care, Cost and Maintenance
Regular Cleaning
We recommend disassembling and cleaning the pump every 2-4 weeks to prevent algae buildup and maintain flow. Soak parts in a vinegar solution to dissolve calcium deposits.
Impeller Inspection
Our team advises checking the impeller for wear or debris monthly. A damaged impeller can cause noise and reduced performance.
Cable Management
We suggest securing cords with clips to avoid tangling and ensure safety. Keep the power cord away from water sources to prevent electrical hazards.
Pro tip
Our team recommends positioning the pump near the water surface to create surface agitation, improving oxygen exchange and reducing biofilm buildup.
Frequently asked questions
Why do aquariums need circulation pumps?
Water movement distributes heat, oxygen and nutrients, prevents dead spots where waste settles, and keeps particles suspended so the filter can remove them, which is vital for a healthy tank. Reef tanks especially need strong, varied flow for corals, so a circulation pump or wavemaker is an important part of the setup.
How much flow does a reef tank need?
Reef tanks need much higher turnover than freshwater, often many times the tank volume per hour, with SPS corals wanting strong varied flow and softies preferring more moderate movement. Match total flow to your corals, spread it to avoid dead spots, and avoid blasting corals directly.
Where should I place a wavemaker?
Position wavemakers to spread flow across the entire tank and lift detritus off the substrate so the filter can catch it, avoiding pointing them straight at corals, plants or sand. Aim for even, varied movement with no dead spots for the healthiest tank.
