This is one nice power head
I got this for one of my planted aquariums. It helps keep the water moving and clean. My fish love to swim in front of the thing all the time.

Ordered two of these Koralia 1400 and one of them quit after less than 4 months of use. Have sent it in and will be pleased if serviced and returned/replaced AND the replacement lasts. Seems to create good water movement but < 4 months for a powerhead of this caliber and price is very unacceptable.

About Me Long-time Pet Owner
I use three 750's in combination with smaller Koralia pumps to provide awesome circulation in my 180 gallon reef tank. The 750's allow me to target difficult flow areas to defeat dead spots without disturbing my inhabitants. Yet, I'm most satisfied with the energy efficiency. Multiple units haven't effected my aquariums temperature or power bill. You can't beat these for the money...
Moves a lot of water

Does what it is supposed to do. I use 2 with a wavemaker and they start in the correct direction all of the time and are quiet.
powefull pump worth getting
from toms river nj
Korlia 750 was ther perfect solution for my 75g salt tank i purchsed 2 and am happy. 6 months and 1 month on each so far no problems
Great Product. Purchased 2 magnum 6's for my 125 gallon and they blew the fish around. Now with the 2 750's it's perfect. The soft wide range of flow is great for circulation and the fish love it.
Everything reported to be and more.

Good product, much better than original

It can get junk stuck in crevices. I have 4 in my reef so that I can get the direction of flow perfect. Easily hidden. Overall great reliable product.

The one thing thats great about it could also be its biggest downfall. It uses such little energy that some electrical wave timers get fooled by the current draw. You have to use in line lights to help trigger the switch between two pumps. Otherwise a great, cheap alternative to the more expensive controllabe wave timers.
I love my Hydor 1050 powerheads

Hydor powerheads really blow, lol. My LFS sells the exact same thing for [$] each. I ordered from Big Als, paid[...] Great product for a great price. I use three 1050 GPH and one 1400 GPH in my 90 gallon reef tank. Thinking of buying a couple of smaller flow powerheads to put behind the rock work. When I do decide to buy I will definitely order from Big Als again.
