View Full Version : How many for 180g

Im in the process of building for my 180 6'X2'X2' and undecided on how many lights.

Im going to use a canopy with holes in the top, an open back and a fan on one or both ends. The tank will be a mixed reef with some sps eventually.

Would two of the 24-v2 be enough at 10" above the water or should I use 3, or would two of the 32-v2 be a better option?

FYI, I used 2 of the 32" V1 fixtures on my 180g tank and they did a great job covering the entire tank. I think 3 of the 16" would work as well (maybe better if you have 2 braces).

Thanks for the reply Ron, Ive actually read your build thread on the 125 after your 180 split.
I tried to find your 180 build thread but didn't find one in the search.

I will probably go with two of the 32-v2 fixtures, but my tank hasn't gotten here yet so Ive got time to decide. I like the idea of 2 instead of 3 fixtures.

How high did you mount you 32"?

I took advantage of the sale and purchased two of the 32-v2 today :)

Chopper, I think you'll be quite happy with your choice. The color control is as good as EcoTech Radions in my book and the fixture is so slim and modern looking. Enjoy.

BTW I didn't do a build thread when I did the 180g system.

Well it was one of your threads Ron
Ive read so many doing research they tend to run together after awhile lol

I now have to figure out a way to mount them. I dont want to mount from the ceiling.
I like the mount that ReeKoi sells, just not the price tag, and I cant find a picture over a 6' tank to see if the middle bows. I guess if I dont go that route I will build a canopy and mount them in there.

Do you have a center brace? Any way that you can set the legs on it? If it's a small or narrow brace, maybe you could make a 'fitting' to silicone onto it so the lights legs could work?

My new tank is the first one in 12 years to have lights with legs since way back when I was using t8 fluorescents... back in the dark ages!

There are two braces across the top at the 1/3 and 2/3 marks. If I lay them perpendicular to the stand I should be able to attach them to the tank walls inside my canopy. Otherwise if I want to put them parallel to the tank I believe I would need to create a fitting.

I have the same kind of 180 brace setup. I'm still playing around with my lighting as I give a setup several years to see how things react and see what I really like or don't like.

Just posted this in my long running tank like journal on what I'm going with next. But I think the reef breeders are a great value and what I hear great support.

And if you have a canopy here's what I did with 3 16" fixtures. You can then adjust left/right and tilt as you want.

Is there a required distance from the water?

If you have a canopy and plan to fix them in it rather than use the legs, it really doesn't make much difference what you do. The way Jayson did his makes perfect sense to me, but I don't think you'd get much, if any, shadow by using two 32" fixtures over 2 braces as long as the fixture is more than 6" to 8" or more, above the brace.

For those of us less familiar with the shorthand, what manufacturer is the "V2" from?

Reef Breeders. This is their sponsor sub forum section.

Thanks for the replies, I like the way you did that inside the canopy Jason.
What size wooden rods did you use? I have the 32" Im wondering if they will sag from the weight.
Im working my way through your build thread, you may have answered this, but I havent seen it yet.

It is pressure treated strip. I cant remember the exact dimensions. Something like .5"x1"

I originally got them to mount 60" reefbrite strips. I have the wood secured on the ends and the middle as the canopy has cross braces there.

Reef Breeders sold a fixture called a Photon for about 4+ years. The new version is called a Photon V2. They come in various lengths, 16", 24", 32", 48" and 50".

Well Ive been slacking on getting my canopy done. Ive been mostly working on my stand, it is finished, it just needs skinned.
On another note I bought a 210 gallon instead of the 180, it is 72X24X29.
What is the best height for two of the Photon 32v? I havent started on the canopy yet so I was thinking of building them into the top of my canopy or run a bar across like Jason and make the canopy 12" tall. That would put them about 11 1/2" from the water, if on top or whatever height if I mount like jason.

How do you tag someone, or can you?

Tagging worked.

I had mine about 7-8" off the water and wished my canopy was taller so they could be higher up. I'd say at least 12" up would be good. Which the canopy would need to be taller then that.

Thanks for replying jason, Im really thinking of building them into the top.
I ran into a snag today, my 30 year old table saw quit working, so I need to go out and buy another. Ive been putting that off for a few years, now I dont have a choice lol.

I could get by without one, but Im cutting down rough cedar I got from my dad so I really need a table saw. Im thinking of 12-13" height and have them recessed into the top with a door in the front.

Chopper, if you ever really want to get ahold of somebody here, you can send them a PM or even an email thru RC. I get quite a few.

I assume your concern about fixture height off the water is related to coverage in the tank and not light intensity (you have dimming for that)? You want the fixtures high enough to cover the bottom of the tank but not so high that they spill light out the ends or front of the tank. I'd make a rectangle that is 24" x 36" which is half the bottom of your tank. Then fire up a fixture and see how high off that test rectangle you need to go to get good full coverage. Given you will have a canopy, consider moving the fixture as far forward over the tank as you can comfortably inside the canopy and then tip the fixture slightly toward the back. That will get you better light from the front of the tank and under ledges and coral shelves that cause shadows, especially with leds. My guess is that over a 29" deep tank, you can be close to the water, like 6" to 8". But that also makes working in the tank with long arms and other tools or getting big coral colonies in or out of the tank more difficult.

I had my old 32" fixtures that were over my 180g tank at 12" off the water and almost right at the front edge of the tank and tipped back about 20 to 25 degrees. The other option is to put the led fixtures up high in the middle (front to back) and add a t5 fluorescent at the front edge for reducing shadows. You could even add a blue t5 at the back and create a bit deeper (thicker) looking tank. The bluer light at the back creates an optical illusion that the tank is thicker than it really is.

I have to admit that I really enjoy my new tanks with the fixtures on legs and no canopy. They are almost high enough already, but if I'm doing serious work in the tank, like redoing the rockscape, I can easily slide the fixture to the back edge of the tank. And I think the V2's are so slim that they look good and the whole system looks more modern, lighter and more airy feeling.

My old 180g with a canopy. BTW, I loved the fabric front and side curtains. It made getting into the tank so easy!

And the new system using the legs and no canopy.

Id really like to just have the lights over the tank and no canopy, but I havent found a way to mount them that I like.

I will try the mock up of half the tank and see what height gives best coverage.
Thanks for all the advice, if I can find a way to mount them without a canopy, I'll prob do it, just gotta keep looking.

I have a 210 that is 72 x 24 x 29 with 2 top braces. I have 2 32 inch v2's.
I built a canopy and made 2 shelves in it for the lights to sit on. The shelves are on the ends and in the center. I can slide the lights front to back if I need to. They only come out enough to allow the lights to slide in, but without covering any of the individual LED's on each end.

Can you put up some photos? I would love to see how you have your lights set up!

I don't have any photos, but can take some later. This is an illustration of the front view. The lights are the blue lines.
The canopy rests on the part at the bottom that goes inward. I made the canopy out of 1 x 4 pine and skinned the door and sides with beadboard and the top and back with really thin plywood (maybe luan?), and painted the inside white.
I have a piano hinge across the to front and one big door that lifts on the hinge.
The wires go out the back of the canopy.
