Default Cyno outbreak after changing lights

I've just upgraded my lights to MH from NO fluorescents and now I have a huge Cynobacteria outbreak. Is this normal?

Did you acclimatize your tank to the lights? Or just pop em in? I made that mistake and had the same problem =(

It only lasted about a week,

Yeah (I think) it's fairly normal to have an small outbreak if you up your lighting. It should be temporary..

I followed an acclimitisation procedure of 1hr on 1 hr off for two days and then upping the on time by 15 minutes every two days.

I'll relax about the cyno then and see what it looks like in a week's time.

Thanks guys.

I guess that explains my cyano then, as I was a little impatient with the "ramping up" part......

I definitely feel that my cyano problem is a mixture of insufficient skimming and flow.

It is normal to get an algae outbrake soon after changing lamps or moving to a completely new type (ie. to MH's). However, usually this is indicative of a problem present with the nutrient levels in your tank when you made the switch.

Think of the light as acting as a catalyst to fuel the even faster uptake of nutrients from your tank in to the given form of algae. This is essentially what is happening.

Interesting to note here is that cyanobacteria is not algae, however it relies on similar imputs of nutrients to spread. Once established, it has the unique ability to assimilate dissolved nitrogen from the water, as part of it's tissue! Thus it is important to remove cyano when noticed, and even medicate to kill it if it becomes substantially established. You really don't need more nitrogen input... you have enough in your food!

watch your corals, 2 days is a little short of the recomended 4 to 5 days but things should be fine.
