Could I Get Away With 3 AI Sol?
 

So i bought one AI sol to try it out and to determine how many more id need.

here i took a picture of my tank with the light in 3 different positions and then stitched it together

seems like the light spread is pretty good and the bright ness is pretty good.

would probably get a a couple more Par38 LEDs for the ends

I'd be interested as well.

AI has a chart and looking at it for my display since the fixtures will be close to the water I'm looking for 5 units (as opposed to 3 if higher) and that's compared to the 2x250W MH that I know is sufficient for SPS growth.

Guess the issue is spread.

Nice idea the stitching

5 units equal to 2 250watt halides?

i read that 1 unit is equal to a 250 watt halide

Looks good marko

I went and bought 2 more

how high will your lights be above the water?

About 5 inches. Same as my mh where. I'm actually getting more spread from each ai than I did with each halide

Since your AI Modules are less than 12" from the water surface 5 or 6 modules is the way to go on a 72"+ aquarium. I assume you have have changed the way they are mounted. Pics show them parallel with front glass.

I've been debating switching over to the SOLS as well, my heart was hoping for three but my brain is saying five.

Start with 3 and mount them high. (above 12") Depending on coral placement all will be fine....especially for new systems where you are just adding coral.
If you have a well established fully stocked display then go with the 5 right away.
