LEDs Causing Algae on Sandbed

[Cal_stir]

i have some too, it's really sticky and doesn't vac up good, i have been running led for a year now but the algae started a few months ago after i switched to H2Ocean salt, my salt mix pail has the same colour residue in it

Nobody with LEDs having this issue or have any suggestions?

The fact that you are sure your problem is only do to lighting is probably keeping most from replying. Lighting plays a part, but only a part. You need to identify the problem. Pictures would help. Are there bubbles in it? Does it go away every night and build during the day? Copper in color sounds like dinoflagellates or cyano. Either way, manual removal and reduced nutrients is the proven method for either.

I found the same thing with my super blue... but that was when I was running power up to about 80%. I now peak at 70% with out any ill effects on coral, I may even try bringing it back to 65%. Algae growth has calmed right down.

Get a Sand Sifting goby to turn the sand for you.

I got a question for all you guys running the ai units. I have seem how nice the ai sol units look and now I am contemplating on switching over to 6 units for my 300dd marine land tank. I will be going mostly sps, small amunt of lps and some clams, so my question is about the coverage of these units. Would 6 units be enough to cover that deep demension tank or do I need to go with 9 units? I have followed some ai users on rc and it seems that most of them if running a sps tank, they are using 9 to even 12 units for a sizable tank like mine. If this is the case then it might not be worth it for me even at 399 plus tax a unit.

sorry for derailing the thread.

It's calmed down a bit since I backed the lights down. There's no bubbles at all in the algae and it forms during the day when the lights are on. I thought for sure it was due to not enough white light. Just didn't want to crank up the white and fry my corals. As for pics I did try to take some but they turned out cartoonish looking. I'll pass on the sandsifter. They always seem to bury peoples favorite corals. What are others with these lights have your settings at?
