Orbit 2 or 4 for 75 gal?

[PRReefNoob]

Hey all, I have a 75 gallon tank with my return pump diverted into two "heads" as well as two tunse 6040's. I recently had one of my Tunse 6040s go out and am considering replacing it with an Orbit 2 or Orbit 4. I was going to just go with the 4 because the difference was like 50$, but some of the reviews made it seem like it was too strong for smaller and medium tanks even on lower settings. Was wondering if anyone has any advice or recommendations? Plan is to have Orbit on one side and Tunse on other and kind of play with the two return heads until I get some pulsing action I like! Thanks!

Tunse 6040s go out

Check if it's under warranty....also try replacing the impeller (and of course giving a thorough disassembly-cleaning) if you aren't sure what's wrong with it.
