Flow rate in display

[jascymcl]

My question is, how much flowrate is needed or recommended fo a 75 gal that will be set up for Z&P's and lps. Some soft. Will 2 Koralias 750 work. Which koralias would you recommend and how many.

I have (2) of the older K 3's on my 75 along with the return. They put out about 850 gph and I have lps, sps and clams so I would say it is enough. I also tried a K4 initially with those and had to take it out cause it was too much flow. I could not place my frog spawn anywhere in the tank that it did not get blown around too much and wouldn't open all the way.

I use two Tunze 6025s in my 90 which I think are the same as Koralia 2s.
