Cyano and LEDs?
Woah! Just switched out my T5s with LEDs this morning, and the cyano outbreak I've been battling has become way worse in the last two hours. It is all over the place now, where as before it was limited to a few places on the sand bed.
Coincidence? Am I just seeing it more clearly now? Or, does cyano just really like LEDs? Everything in the tank looks good, so I think my light setting are probably pretty close to what the tank's inhabitants are used to.

What do you have the led's set at %? if you just put them on the tank today then they should be at a low % for awhile them increase it over time so everything can adjust to the increased light.

They're at 45%, and 12" above the tank. I had them at 11" above the tank, but I didn't like the way a couple of my SPS were looking. Moving it up to 12" the SPS look better.
The t5s were 2" above the tank.

cyano algae is caused from high levels of nitrate and or phosphate so control them and you will control cyano algae. What are you using for water? tap or RO? What is your bio load? The leds aren't causing it but might be able to see it better now.

High bio load. Zero phosphates using the Hanna Checker. 0 Nitrates on the ELOS test. RO/DI water. Changed carbon and ROWAphos last week. Not skimming, as the skimmer still isn't producing foam since I changed the reactor media.
Haven't had to remove film algae from the glass in five days. The cyano issue was very close to being resolved, so this is a bit shocking. Nothing has died. Everything is accounted for. The LEDs have 40 degree optics.

Do you have a sand bed? How old is your set up?
