Added new light

I just installed an Aqualight retro, it is 260 watts 10K at Act. I previously only had a 40 watt single tube 10 K light. What precautions should I take with this light? I don't have any corals, just fish and live rock. I know when going to MH's you need to allow time for the tank to adjust to the brighter light, should I do the same, or just run them?


By the way, this light is awesome compared to what I had. Great light

Wow, you have a lot of fish. I wouldn't worry, the brighter light may make the fish skittish at first but I don't think you need to do any special acclimation. With corals the photosynthetic cells need time to adjust to the brighter light.

e there is nothing in your tank that will be burned by a sudden increase in light...I think you should still acclimate the tank slowly, or you might experience a serious algae bloom.

What if one would be getting an algae bloom from a sudden increase in lighting, say adding 32 watts to 56 watts (which may have been upgraded from 24 without any transition only a couple of weeks earlier)?

What is a proper transition? What should one do now?

Most of what i have read says about that.. Just make sure you take your time acclimating to the new light.. Start slow as 2 hours the first day or less.. then increase 30 mins per day after....

I agree with reefrunner. Algae bloom is your big concern with that type of lighting.
