I want to add more flow to my tank because I am mainly keeping SPS Corals.

Current set up has my two return lines (3/4" each) have penductors/educators on the end. The pump is a Mag12.

Option #1 above would be to add two powerheads to the back of the tank and point them either forward or on a slight angle toward the left and right side of the tank. The two powerheads I'm looking at are the Tunze Nanostream 6025 or Hydro Korilla 2.

Option #2 above would be to change my return pump to a Mag18 and T the 3/4" return lines so that I have four 3/4" eductors/penductors.

What are the pro's and con's of each? Which option would provide the best flow inside the tank?

Thanks,

this will give you more water turn over. your overflows will only handel 600GPH so adding a bigger pump will not help as much.

I would do Option #1 too but if you choose Koralias, do the 4. I've got a 120gal as well and the 2 K4s are perfect. I may add one more.
