Energy-efficient reef circulation — wide flow, quiet magnet mount, three flow attachments included.
Hydor Koralia 3G (G3 / Third Generation) is a high-efficiency circulation and wave pump built for reef aquariums and suitable for freshwater tanks too. A new motor, propeller profile, and intake spiral grid deliver strong continuous flow at very low wattage — about 1 W for every 1,450 L/h. The patented Dual Magnet Support System (DMSS) mounts on glass up to 15 mm, pivots in virtually any direction, and uses vibration-absorbing silicone for quiet running. Spiral cable protection helps with puffers, triggers, and similar fish; three included grids customise flow shape and protect small livestock.
Three sizes cover 5,000–9,000 L/h for reef circulation, coral and plant movement, and timer-driven wave patterns on marine and freshwater displays.

Quarantine
UNPARALLEDED QUARANTINE PROCESS
Our comprehensive quarantine process utilizes a powerful combination of copper, prazi, formalin, and antibiotics to tackle even the most stubborn diseases. This rigorous treatment ensures our fish are free from common ailments like Ich, Velvet, Blackspot, Brooklyenella, Flukes, Tapeworm, Uronema, and Vibrio, which other treatments like TTM and hypo may not cover.
Fish are fed 3x a day and will be transferred to a sterile system with UV for their remaining stay.
Tangs are treated more strictly with quarantine and will hold any fish for longer if symptoms are still displayed.
2 WEEKS
Two weeks is just a minimum, you are welcome to quarantine further if you wish. As most of the work is already done for you, rest assured that the fish received from REEF HAVEN AQUARIUM are very healthy.
PLEASE NOTE: We DO NOT guarantee 100% parasite free fish. We still recommend that you quarantine regardless, but the time taken to do so may be a lot less than usual. If you purchase fish that have not been quarantined, they may still be a carrier for parasites. Parasites can lay dormant in your tank until a new stressed fish is introduced. Corals & inverts may also introduce disease if coming from parasite infested waters. Natural sea water WILL introduce parasites.
ERROR-FREE MEDICATION
Our medication process is handled by a single expert, Hazel, guaranteeing zero room for error. This personalized care ensures our fish receive the precise treatment they need, without the risk of human error that can occur with multiple handlers.
HEALTH STANDARD, NOT EXTRA COST
At REEF HAVEN AQUARIUM, we believe healthy fish should be the norm, not an added expense. That's why we incorporate our quarantine service as a standard health practice for all our fish, at no extra cost to you.
