I can add a couple more OctoPulse 2’s and run 4 pumps…Flow is more important for SPS then PAR. IMO.
I run an 80G cube, I run 2 mp10's, 2 jebao pp8's, 2 nero3's, and RFG nozzles on my returns. Granted I don't run all these on 100%, but I do run them all at the same time to create random flow patterns. Corals do not like laminar(one way) flow.
