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

amen to that. changed everything for me.

[quote=Blom;648607]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.[/QUOTE
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?

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.

Im not to sure, but I know you can change out the optics. Standard is 4 outside pods with 70 degree optics and the 4 inner pods are 40 degree optics. I know from my single ai sol unit that there is a lot more light directly under it which I could see leading to a "spotlight" effect if multiple units were used. When you order you can specify that you would like 70 degree optics all around and no additional cost. (pretty sure its no additional cost)

Thanks for the reply Blom. I might just use my 3x250 halide inconjunction with 3 ai sol units and see how that goes first.

You should be good with 6. My tanks 57" long, rounds out at the front 29" and is 25" deep. There's SPS, LPS, zoas, a clam anemone and all doing great. You'd be better off supplementing with purple or pink T5s to bring out your reds. I like mine but this algae thing is my only complaint and i'm positive it's due to a setting that I have yet to figure out.

my 230 has them mounted 12 inches off the water, and is an additional 30 inches to the bottom, with 24 inches wide.... I have 5 units with a fully stocked SPS tank, and no spot light effect at all....

Thanks guys for your reply.
