More flow in my 75?

[vette.tech]

Right now in my 75 i have a wp25 thats on one end, its on the corner overflow because my tank is in wall and i don't have access to the sides, well i can slip a koralia magnet behind on the opposite side but i kind of want a vortech and that would not fit and would have to go on the back wall, i was thinking of putting an mp10 on the back wall on the opposite side of the wp25. I currently have a bunch of koralias like the 1150 and 1050 but they are too much flow when added into the wp. It just blows sand around and the coral flesh hangs on for dear life. Do i even need any more flow than i already have?

Also have a return pushing about 700 but thats on the same side and flows into the path of the wp

was also maybe thinking about turning my return into a second drain and running the return up to the other side of the tank and putting on a sea swirl or something...???
