The reasoning for the the 4 XR15 is, if you look at the tank it can be divided into 4 18x18 cubes. PLus, if i were to do Xr30's I would need 3 to cover the 7' length and I'd have to figure out how to mount the middle one since the overflow box is there.
Nicely done - great design work
Looks great with the new lights
I'm planning plan for same dimension, following
I was going to ask the same thing about the lighting choice.
I have the same length tank. 7x2x2.
I hung my Radion Pros lengthwise and had 4 of them, which is double your amount of pucks, and I still questioned the amount of light being not enough. It's not the intensity (my lights were around 60%) it's the coverage. I see this tank is in the SPS forum. That's just not enough light coverage IMHO. You will have a lot of shadowing.
After nearly two years, I got tired of the shadowing and poor sps growth and color and switched back to 3 MH and 4 T5's. Color and growth exploded. A result of what I believe is both spectrum AND much much much better light coverage. The undersides of my sps are no longer bald/colorless.
Other than that, great build. Been following along.
How's the "fish room" coming along????
Thanks for your thoughts/review on the lighting. I've not had much time lately to admire the tank as I'm still working on other things around the house. With the rock work fairly bare, I can't see much shadowing as of yet. My lights are still in acclimation mode at 30% of 60%.
Originally I was going to go with 3 XR30 pros, but the 4 XR15 sounded like a better idea because I could space out the lighting equally. The idea of adding a 5th one is not out of the question.
Were you running the 120 degree optics on your lights? I wonder it your dimensions were just too wide for the lights? My tank is very narrow and shallow.
What was your light cycle like and what were your lighting settings?
I'm very new to leds and I'm still looking for more info on manual colour settings.
I've always been a die hard MH guy. But after using t5, found it to be the best. For me anyways. LEDS are hit or miss when it comes to growth and coloration from what I've read throughout the years. I'm hoping I can get great results with this lighting.
At the end of the day, colour and growth is the most important. I hope it can get it with these XR15 pros.
As for the fish room, it's a lot smaller then I imagined Everything in there is kind of thrown together late minute and I've not had a chance to clean it up and make it presentable. But I'll get to it soon!
Thanks for stopping in, I'm a fan of your builds as well

Wow, sick updates! The build looks amazing!
Yes, I had the wide angle lenses.
And nothing against Radions, they are a really nice led unit backed by a great company... i just think, based on personal experience, that with the length of your tank, you will need more pucks than you have now. Due to the narrowness of your tank (front to back) I agree that you only need the single pucks, the same reason i hung my radion pros lengthwise over my tank (i have a coast to coast overflow taking up 5-6" of my 24" of space). I don't know if somehow Ecotech improved the coverage of these individual pucks vs the dual pucks in the the original units, but I had twice the amount of pucks over the same length tank. That's what I was getting at earlier.
Your T5's give the ultimate in light wrap/coverage and LEDs give the least. When you look at the coverage diagrams they have, intensity is really dropping off out at the edges and this is with nothing in the way. Once that light is coming down and hitting coral, the coral will block most of it. Since its a pinpoint light source, the light doesn't wrap around and under the coral anywhere near like it does with T5. Once I switched back to MH/T5 you could see my corals regaining color and growth underneath. Here's an example pic that I had posted in my build thread. You can also see an improvement in the growth pattern, after just a few months.

Here's my last saved schedule if you want to upload it and give it a go.
Just remember to save your current one first so you can revert back to it.

As to the fish room... i'll be redesigning mine and I'm in the same boat! Trying to cram everything into a rather small space. From what I had seen yours had started off pretty good so I'm curious how it turned out.
I just want to get the lights up to 60%. I shouldn't have to go any higher then that right?

Thanks for taking the time to comment on the lighting. The lighting so far seem to be working out for the most part. The tank is still settling in and I'm finally starting to see a how the chemisrty is in this tank.
This is a whole new experience for me. Instant ocean salt and Leds are the two big changes this time around.
I'm hoping I will get great results with this new tank. Only time will tell and I'll be sure to update this thread as time goes by.
thanks again.
Don't mean to make this become an ledxT5 battle(we are all tired of it) but all I gotta say is try it for yourself and make your own conclusions...
Oh good no battle, because I'm one of those guys with 40+ years in the hobby, I have used every lighting system every offered and love my Kessil LEDs. Great color and growth. All the T5s and MH are sitting in the garage.
Do try it for yourself and make your own conclusions. You'll be happily surprised.
Looks awesome!
This has been a great build thread.
I will echo the others that you might want to add some more LEDs over the tank. Most of the best LED lit tanks I've seen dramatically exceed manufacturer recommendations in terms of the number of emitters they use. If you choose to stick with LEDs, keep an eye on the sides/undersides/bases of your corals to make sure they're getting enough light.
Make sure you watch Ca and Mg. IME, plain ole IO tends to be a bit low on both.
Thank you for the compliments and thanks for the point on the extra lighting. I'm far to new to see lack of lighting on my corals, since they are all frags. I'm still in the acclimation stage so the lights are only at 50% of 60% of total intensity. I think they are drawing less then 100watts right now
As for the IO salt, I have noticed the lower numbers in CA and MG. I've been dosing my make up water. Maybe I should swap to Reefcrystals? Same stuff, just a bit more go the Mg and CA right?
Update time!
