Which pumps should I use? Wp25 or wp 40 (90g mixed)

[scason]

Mainly a softie/lps tank. But planning on a few sticks at the peaks bit after lighting is upgraded. Currently have it fed by a mag 18 split to both corners. Is have a wp10 I plan on keeping in there but want to ditch the koralia pump. Equipment was originally used in a 37 bow but need more flow. So 2x wp25 or 2x wp 40 opposing each other with the wp10 in the middle. Standard 90g

I have a 5 foot 100G mixed reef with two WP25's. Love them. They will move sand at the opposite end of the tank if not aimed properly so have plenty of flow.
I originally bought a WP40 but it looked huge compared to the 25's so I sold it.

As suggested above though, you might want to consider the newer RW series pumps, even smaller, more flow and more features for about the same $$.
