Not necessarily. 600 gph
with a Koralia is very different than 600 gph
with a Maxijet. The Koralia flow is waaaaaay more dispersed. I have a Koralia2 in my tank and using the "hand in the water a few inches in front" method of sensing flow, I'd say it's more like a Maxijet 900 (230 gph
) when it comes to generating current in a tank. Yeah... not very scientific, but you get the idea.
Bavass... don't necessarily base your flow requirements on what you see in other folk's tanks. Base it upon your own needs. It's not a bad thing to have some low flow areas of the tank - there are a lot of corals that don't like a lot of flow, and that gives you a place to put those. If all your tank is like the ocean in a hurricane, it really limits what types of corals you can get. With that said though... I don't think 2x K2 in a 55g is too much flow, depending on your rockwork. I can easily see putting another one in there, no problem. If you do and you don't like the effect, then you can always pull it back out and just use it as a spare for the others!
