So the question is, is it better to replace my main pump (that runs 24 hrs/day) with a DC pump. Or replace 500w of MH lighting with LED (that runs 8.5 hrs/day).
What are peoples thoughts?
My Sedra KSP-7000 claims to use 70watts (versus 25watts for the DC pump), but my AquaController says that it lies! It uses at least 100watts probably due to the head pressure (and maybe more. I think it commonly uses 1 amp or more)
