2 Disappointed!	01/18/2009 - by Anthony S from Ridgefield, CT US
I purchased the Koralia1 which lists a flow rate of 400 GPH.....not even close. The flow on this pump is very weak. Your money would be better spent on another brand of pump. I have several Maxijets and $ for $ they are hands down better than this pump for water flow.
5 love it...	12/27/2007 - by tom mcmahon from southfield, MI US
i am using both the hydor 1 and 2 in my 29 gallon cube using a seio controller which allows them to be operated in a surge/pulsating pattern with your choice of time intervals ranging from 15 seconds to 60 minutes. they are very quiet, reliable and move a lot of water in a broad swath than conventional powerheads. the only drawbacks to some might be their size and the distance they protrude into the tank and at times i do have a polarity problem where the impeller spins in the opposite direction after being turned off for a while ( reversing the plug in the outlets corrects that). overall i think they are great pumps for the price.
3 Not bad...but	10/23/2007 - by michael weiler from fargo, ND US
These pumps are not bad but flow is weak due to uneven output and V shaped flow. I would not recommend using these on anything bigger than a 40 breeder. But because of there size using them on such a small tank would aesthetically be not so pleasing
3 decent for the price	09/20/2007 - by brassmonky from florida
the price is right but has some drawbacks. the flow is uneven on the output. forms more of a V then a cone. kinda long and hard to position in a cube, but not a problem with normal shaped tanks. one started to rattle after a few months.
5 Awesome & Affordable	03/01/2007 - by Jason from Michigan
I love this thing! I replaced a SEIO 620 that was a little too much for my 30 gallon mixed reef with the Koralia 1, which is just right for my tank. It moves water in a wider swath than the SEIO. Best fo all, it won't break the bank like some of the other high flow/low velocity powerheads!
5 Great Deal!	02/28/2007 - by Ryan from Ohio
At half the price of a Tunze Nanostream 6025, these are a steal! They are nearly as good build quality as the Tunze, and I like the design of the magnet holder better.
