Power Head

[kennygater]

hi i am setting up a marine tank and need about 6000- 7000 lph. is it better to have a few powerheads moving in different directions or is it better to just have one? thanks

more than one is always better, you will find you will get a more even flow the more you have . also it will not be as harsh on your coral/fish

Agreed, 2-3 seems to be the magic number
