Not really, depending on what you plan to stock the tank with you might be fine. My friend uses 1 mp40 in a reefer 350 with a good amount of acros and his tank is killer!! It all depends on placement and how you stock itwhat the??? I am way underpowered comparing to some people here. For my 95g cube I am setting up, I plan on two mp40. I guess I need a third. LOL
I have a current 29gal tank and using a Tidal 75 as my hang in filter and the flow is pretty strong I have 3 torches and they love it, I wanted to frag a birdsnest from my main 175gal and see if it likes it in the 29gal to experiment if it’ll survive. (Ofc if I see any issues with the frag during the process he’ll go back in the 175gal)Water movement in a saltwater reef aquarium is important on so many levels so using the right powerheads in the right configuration for your tank is a pretty big deal! That being said there is not a "one size fits all" solution when it comes to the number of powerheads you need, which brands you use or where they should be placed. For the most part anyway. But it should still be interesting to see how many powerheads are members are using!
1. How many powerheads do you have in your saltwater aquarium? (what size tank do you have)
2. Which powerheads are you using?
