    This is just a general question. I know that when dealing with corals that the change from T5 to LED needs to take place slowly to allow for adjustment. My question is, has there been any thoughts or talk about the effects of LED lighting, compared to T5 or other classic lights, and the benificial bacteria established in a tank.

    Will there be some die off and a mini cycle after the switch?

    I just placed an order with reefbreeders, outstanding customer service by the way, and am curious what I will experience in the switch from T5 to LED.

    The bacteria in the tank should be unaffected by the change over to LED.

    When switching from m/h to led I did notice some algae die off which is good but it did cause a slight rise in nitrates.I didn't have alot of algae but I think there was more in the nooks and crannies than I realized,my m/h bulb was way overdue for replacement.

    If I think of photoautotrophic bacteria in a reef, the first example in my head would be cyanobacteria. I think most wouldn't call this "good bacteria" (although there could be some benefits). Otherwise, I don't think much bacteria in our tanks will be effected directly by light. There will likely be some interactions between bacteria and other organisms, such as algae. So, light could change the ecology and indirectly effect more bacteria. Also, there is a competition for surface space, so, as algae, dies, or thrives, this will likely effect the dynamics of the environment. I think it's safe to say bacterial populations change with slight environmental changes. However, it also seems that bacterial populations can shift pretty significantly with small perturbations, so, much so that it is tough to actually study the dynamics of a complex microbial system. So, we can think about it, but probably don't know enough to do much other than guess...

    Ah, technically I "TYPED" it, thank you very much :p What can I say, it was what was written in the captions of my getting started in reefing picture book :)
