Review on ๐ Koralia 3G - Advanced Generation circulation and wavemaker pump by Alfreada Leotta
Not the best Hydor pump, poor flow
Bought several of these for my 90 gallons. Reef tank in 2016 with older Hydor Koralia third pump. On the plus side, they're quiet. However, they don't produce much flux, and what they produce spreads very widely and scatters it further. Two of them will not provide enough flow in a 90 gallon tank. The old pump recently failed after 5 years and I replaced it with a Hydor Koralia Evolution 1400-1500 GPH pump which produces more than double the circulation compared to the 3rd generation 3G pumps. I moved down one of those 3Gs that runs the full length of the tank and it doesn't even mix the sand.
- High marks for support and durability from testers
- Crumpled
