What a tank! Those corals remind me of weeds growing wild. Very good job thereAnother vote for the Spectra, truly an awesome fixture. MH/T5 is hard to be IMO, I’m running Radiums, Blue+, and Actinic.
Also believe it comes down to preference, especially if you’re having success with the type of lighting you’re using. My first tanks were MH/VHO, so I prefer that type of look.
Who knows, if I were starting out in the hobby today I may think led is the only way to go. I have seen a few awesome tanks lit by led but it’s just not for me.....yet
