Product Description

The Koralia Evolution 850 gph is one of Hydor's new and innovative wavemaker and circulation pumps for small reef and fresh water aquariums. The Hydor Koralia Evolution design and technology guarantees a continuous and powerful water flow which can be directed freely thanks to the special sphere-shaped connection to the exclusive combination suction cup and magnet support. High performance, low energy consumption and quick and easy maintenance. Includes cable protector and is ideal to use in tanks with urchins, triggers, puffers and parrot fish. Unlike the non-Evolution Koralia pumps, the Koralia Evolution can be connected to a Wavemaker. Please note, if you are using the Hydor Koralia Wavemaker, you will need to use one of the Koralia 12V Controllable Powerheads.

WARNING:

CHOKING HAZARD -- Small parts. Not for children under 3 yrs.

Customers like the flow of the pet supplies. They say it provides a decent amount of flow that keeps the surface moving and the bottom clean. Customers also say it's a great continuous flow pump that runs very quiet. The multiple props move water in a much larger scale and circulate it. The water flow pattern is gentle and wide, and the fish love it. Customers have also noticed that their zoas are enjoying the extra flow and opening more quickly.

71 customers mention61 positive10 negative

Customers like the magnet on the pet supplies. They mention that the magnet is very strong, and the strong magnetic suction cup keeps the pump anchored to the wall. The combo magnet/suction is fantastic, and works like champs. The magnet mounting mechanism is solid, and it's an attractive and functional way to mount it to the tank.

Works, BUT THERE IS AN ISSUE.

Works, BUT THERE IS AN ISSUE.
Bought this Model as well as the 750-850 GPH. Both developed the same problem after about 6 months of use. There is a rubber bumper attached to the inside of the grill which prevents the impeller from going into reverse when the motor starts. If you are going to attach these pumps to a unit like the Hydor Koralia Smart Wave controller which cycles the pumps on and off at the set intervals, ( in my case it's every 10 seconds ) the bumper is eventually going to break off. The repeated hitting on the bumper by the impeller is going to weaken the thin area of the grill where the bumper is mounted. Had to use lots of Super Glue Gel to reattach the broken off parts. So far they are holding up.If you are going to have the pump running non-stop 24/7, then this problem should not occur.Reported the issue to Hydor, they offered to send me a replacement grill. Declined, as the same thing will happen again 6 months down the road. Guess I will be switching brands.

Bomba de circulación trabajando excelente. Al contrario de otros comentarios estas bombas tienen suficiente flujo y son muy buenas dándoles el mantenimiento apropiado. Buenos materiales. Armen bien sus bombas y lean las instrucciones antes de montarla, de ahí vienen los problemas que han tenido ciertas personas.
