Description
Keep the Whole Reservoir Moving, Not Just the Top of It
The Newave NWA range is a set of high-performance circulation pumps with low power consumption, used so nutrients do not sit at the bottom of the tank. They re-create a natural current, keeping solution in constant movement to avoid stagnant water. Each pump fixes with a magnetic holder on a ball joint, one magnet inside the tank and one outside, giving totally directional flow. Six models cover 1900 L/H to 13300 L/H for reservoirs from 100L to 800L.
Key Benefits
- 1900 L/H to 13300 L/H across six models, for reservoirs of 100L to 800L
- Constant movement keeps nutrients in suspension rather than settling out
- Magnetic holder and ball joint for fully directional flow
- Flow adjuster to soften the current in smaller reservoirs
- Self-cleaning, high-efficiency impeller that works without a strip-down
- Extremely quiet and reliable, with a built-in power cord guide
- 30% improved performance over the older model
What Actually Happens When Nutrient Sits Still?
Left alone, a reservoir separates. Heavier elements drop out of solution, the top of the tank reads a different EC to the bottom, dissolved oxygen falls and still, warm water suits root pathogens. Plants fed from it show weak roots, poor nutrient uptake and slow growth that no change to the feed will fix.
How to Use
- Match the model to the tank: 1900 for 100L, 3200 for 190L, 5900 for 350L, 7500 for 450L, 10700 for 600L, 13300 for 800L
- Mount it: magnet on a clean inside wall, below solution level, with its partner on the outside of the tank
- Aim it: angle flow across the tank floor, where sediment gathers
- Dial it back: use the flow adjuster if the current churns the surface
- Run it: continuously, or on a timer between feeds, to keep EC even
- Maintain it: rinse the impeller housing between crops, and never run it dry
