KORALIA is a new innovative range of aquarium circulation pumps. Designed to be super efficient and long-lasting with very low energy consumption compared to traditional circulation pumps. KORALIA’s water flow is both powerful and delicate making it ideal for marine and reef tanks. The unique patented* magnetic support allows free and secure positioning anywhere in aquariums with glass up to 15mm (0,6 in) thick.The special sphere shaped connection makes flow directing quick, simple and fully adjustable.
Been using the evo750 nearly 2 yrs. now. The wide flow never hurt my new baby Labs. Though at times I wish I had went with a pair of 1050's for my 75 gal. I contacted Hydor online and seems the 550,750,1050 and 1400 all have the same footprint. Difference is strength of motor and impeller. Great to know an upgrade in flow does not result in a larger body.
I really wonder who designed this pump. The overall design is great. The power is really good. My only problem is with the impeller. If you look closely at the magnetic part of this piece you will see MANY MANY little seems. Why I dont know. Mine eventually seemed to take on water. That caused a swelling in the impeller!??!??! I have had another type of pump that has performed flawlessly for 20 years. NO LIE! With the same type of impeller/ magnetic drive system. I also dislike the suction cup magenetic "holder", the magent holds but all suction cups fail. ALL SUCTION CUPS FAIL ALL SUCTION CUPS FAIL maybe someone in the hobby supply business will learn someday.Overall the pump really pushes some water.And is easy on power. Just a few little problems I still like it.
This powerhead is a little bulky in aquqrium but it has the flow of a fire hose! It moves all kinds of debris from the bottom of the tank and the FX5 does the rest!!! I would put mine on the side of the tank, pointing the nozzle towards the back and watch it work!!! Fish really like the current it throws. Creates lots of oxygen in the tank as well. As for bulkyness, SACRAFICE A little, BUT GAINED ALOT!!!!! Got them in each of my tanks now!!! Great product!
So far so good. Only minor negative is that food floating the water or plants get sucked into the pump and stuck on the catch screen. Not a big deal though. Magnet so far is strong enough that my 8-10" Cichlids havent been able to knock it off the wall when they attack it. Current is good, easy to change direction. Im happy with it.
Great water movement without the strong jet of a power head. A little over-priced IMO though. Also, as others have stated, they are big and hard to hide. I use mine to provide extra aeration in my 125 gallon sump where you can't see them.
