XSiVE's 120 in-wall

[cg5071]

Thanks. oh! PIF,lol. Ok that is great. I wouldnt mind jumping in either. At one point I was actually hoping that mine would die so I could watch it produce but I just let things take their course.

I am looking at a frag tank also. Probably 20 long or half of a 55. It doesnt need to look purty "yet" Maybe if I was doing one for my main tank which has an ugly light system over it now. I would want a deep blue I guess as I am getting into sps slowly but surely and want them to have nice colors. My main isnt really blue atm since I was growing lps and zoas mostly But will probably change the halide there from a 10k. What do people use for both good growth and bluer color for sps? The halide is over the back of the tank and most of the rock, and I have a couple t5s over the front.

Money of course is important and I am sure I can do most of the work myself. Thanks for the guestimate of cost, and no I dont need it to dim.

First glimpse of PAR numbers (Huge** Thanks to Tom, CalmSeasQuest for letting me borrow the meter!) I will have much more detailed analysis over the next few days.

This is a graph of the light level at about 1cm below the water surface. Think of the bottom, flat section of the graph as a "slice" of my water column, The X-axis (labeled A-I) is the front glass, Z-axis is the side glass, labeled in 6 inch measurements relative to the front glass.


Im very happy with the initial findings. It's nothing like ZOMG SO MUCH LIGHT, but when you think about it you realistically dont need much, if any more light than Im pumping into the display to keep everything you could ever want. Sure the 1cm below water surface on a hawaiian reef is something like 1600-2000 PAR but most of the biodiversity happens at significantly lower light levels.


Side note: Im getting ~150-250PAR on the rack, 400? at the water surface in my frag tank with only 8 emitters, going to add 4 more emitters to that pendant so I can have it more focused on growth for SPS either before they go into the display, or after they get clipped and get to wait for sale. I'll have solid data on the frag tank tomorrow.
