Love MH’s so much I've stocked on Radium bulbs until end of 2021. Ran G4 pros, orphek, ATI t5s, Hydras. MH’s best fulfills my taste on coral growth and color, and visually I just love the look of the tank.
I run them on a giesemann spectra so the sharp look of the fixture doesnt make me miss leds at all.
My tank is a 150 in the basement so the house AC keeps the tank at a cool 79 in the summer without use of a chiller. I supplement it with blue led bars so I have all I need.
Which LED bars are accenting your MHs with? I'm about to do the same. Either Reef Brite XHOs or Orphek Blue Plus.
