I'm in the process of a 120 reef ready build. I acquired a tank that the previous owner removed one of the two monster overflows and used the holes as a small closed loop system. I was thinking of capping the two holes and putting two durso overflows on the remaining overflow(I like the extra space of the removed overflow). One durso could be the main and the other an emergency perhaps. I only plan on running 400-500 gph through my sump. I have to mp40's for the rest of my flow. But back to my original thought, I was wondering if the sea swirl would be worth my while. It's not a ton of flow but I like the idea of the oscillation. When facing the tank the left overflow has been removed so water would go through the overflow on the right and I can put the return on the left pushing the surface stuff towards the overflow. Any experiences on this or suggestions would be greatly appreciated. Oops almost forgot. I plan on doing a mixed reef some sps maybe more as I progress. Thanks in advance
