It's likely due to a shift in the spectrum, as well as more energy, as mentioned above. You could siphon it, but I wouldn't worry too much about it. A reef tank is a dynamic enironment, and will blanace itself out as long as parameters are maintained. Your levels look fine, maybe test PO4 as well, but I bet it's gone in a week or two.

Can someone post a picture of cyano? Not exactly sure what it looks like.

Here is a link to look at.

I also noticed the same thing when I upgraded my MH ballasts. Huge outbreak of the worst kind: dinoflagellates. Took a long 2 month battle to finally get rid of the stuff, much worse than cyano.

The cyno is getting worse today, a little patches every where and I am not happy at all. I have to do major clean up this weekend when doing water change.

I just recalled, before changing the light bulbs, I took out the ceramic bio and added in like 10pounds of uncured live rock. Is this the reason for the algae bloom? Need your input on this one...

I don’t know what the percentage of rocks you have add from the total weights of your rockery and if you cleaned them or cycled them but…..
Yep! That might be just it.
The introduction of dry rock to the system will cause the rise and build up of phosphate and nitrate (decomposing of dead animals in the rock into ammonia -> nitrite-> nitrate)
The cyano just loves these conditions.

I believe you are right. I don't understand that if it is the case then why cyno appears on the old rocks in the tank, not just the new ones? The question is just for my learning experience.

I tested nitrate with Salifer, it is 0.5ppm. I guess it is the end of the cycle. The cyno should clear up soon.
