So my 125 has had numerous lights over it, starting with MH that came with it (along with a huge power bill). Then not knowing any better (but originally running a FOWLR tank) using cheap marineland LEDs from PetSmart. Then MarsAqua black box LEDs and now finally, one of the last upgrades, Hydra 26HDs. Original Mounting of MarsAquas on PVC: (I'm a broke teacher with an expensive hobby) Then with a canopy frame: (about 4 months after PVC frame) And now (drum roll) Hydra 26Hd with HMS rail system: Questions for all of you: -How long do you set your acclimation time to within myAI? -Is anyone running their Hydras with a similar setting to the BRS Investigates - Prime HD AB+ setting? What have you noticed in the tank? -Is there a reason to alter the intensity/spectrum throughout the day rather than just a ramp up/down? Thanks in advance.
