Thanks GC:

I think I'll probably have my lights no higher than 18" above the tank then. My plan now is the 32" Photon V2+ about 18" above my 48"x20"x24" display tank.

Hoping this will work out OK.

Hi, it should work out just fine. Is your tank 20" front to back, or 20" tall? You will really like the Photon light, as it has most of the bells and whistles most people use, they use high quality LED's and have rally good customer service.

Hello all ✌️. I have the oceanvivell t247 over my 36x18x22" aquarium. Been running for approx 8 months. Mixed coral and fish currently stocked. Right now I have the Blues at 75% & whites at 25%, what would you all think my settings should be at? Everything seems to be doing fine just curious.

I think I'm sold on using LEDs - low power consumption and minimal heat. I think there's enough evidence out there to support they do in fact work.

If you are still unsure about leds, let me put your mind to rest. I've been using leds exclusively for the last 5 years. Early on I had Chinese black box leds that I bought directly from EverGrow in China (now Reef Breeders in the US sells the EverGrow made fixtures under the RB name). That was a mixed reef 180g tank and everything grew just fine. They were a basic 2 channel fixture with the ability to do sunrise/sunset, but as far as the light they produced, any 100% black box fixture like MarsAqua will produce virtually the same light and grow coral.

For the last 3 years I've been using Reef Breeders Photon V2 fixtures (still made for them by EverGrow in China. I had a new 120g DT and it was full of sps corals (mostly Acros) and they were colorful, healthy and growing. But I lost them all due to a chiller failure to turn off. So now I have a 40g cube as my DT and I'm still using a RB Photon V2. But this tank is full of zoas and RFS'a (Rock Flower Anemones) that all fluoresce colors like crazy when the blue leds are on. And my RFA's have even spawned 3 times in the last 18 months giving me dozens of babies!

Do I think leds are OK for corals? What do you think?
They make good light, they are able to adjust the look of the tank from white to blue at a touch of your finger, they can do sunrise/sunset, they run very cool, they virtually never need replacement bulbs... I'd only consider t5 or MH if they could get to that level of flexibility (never).

One last point, if budget is an issue, the $100 Mars Aqua basic led fixture can do the job just fine. If budget is less of an issue and you want more features, Reef Breeders Photon V2+ is by far the best value in a full feature fixture. And if money is no object, you are welcome to spend more on EcoTech Radions oe AI Hydras. Although they offer very, very little more in quality or features than the Photon V2+ and cost 50% to 100% more!

Hi Ron, long time member, but not much on posting. I've been out of the hobby for about 10 years and certainly learned a lot from this thread.

I'm starting up a 75g 48x21x18 soon and was intrigued by your comment on using the 32" Reef Breeder on a 4' tank. So, you really think that is a good option? It would save $110, but not sure if that is the best way to go.

Thanks for everything you add this is board!

Hi NormanB. I don't post here much anymore. I moved to a different website forum that is a lot more interactive and has a lot more info and help. In fact they even asked me to volunteer as a 'helper' in a squad of about 50 people to answer the questions the general membership struggle with.

The 32" will work but you need to be clear about a couple of points.

So you'll have 8" off each end of the fixture to the ends of the tank. If you raise the fixture it can certainly light all 48" of tank. HOWEVER, if you are going to have light loving sps corals from wall to wall in the tank, the PAR may be a bit too low for you. It's even possible, if you are really a stickler for appearances, the ends of the tank may be a tiny bit dimmer than the center.

On the other hand, a 48" fixture will have leds all the way out to the extreme ends of the tank and with 120 degree lenses, it will be throwing light outside the end glass. Yes, some of it is reflected back in by the glass. The other difference is the 48" fixture has 4 more blue leds (good), 4 more violet (OK but not a big deal) and 8 more white (and in my humble opinion it has too many whites already, especially since they are 5 watt Crees and not 3 watts like most fixtures.

So if budget is important, super even lighting isn't critical to your eye and you aren't doing sps corals end to end, yes, the 32" can do the job just fine. But I'm just one opinion in a sea of opinions!

Ron, I appreciate your quick response and thoughtful insight.

For $110 I am leaning toward the 48"

Thanks

Hello I have a question about lighting. I am currently working on a 75 gallon predator tank what was wondering what the best led all in one lighting system with remote is? My price range is up to 300$.

Well, for a fish only tank, almost any white light will do, the blue is much more for coral and anemones that use the blue to do photosynthesis. You might look at a Current Orbit fixture. They are less powerful but have way more than enough light for a fish only tank and they have lots of controls and are the least expensive in a full control led fixture.

If you intend to have corals or anemones in the tank, this light will be a bit weak on a 20" to 24" deep tank. The least expensive, full control led fixture would be a Reef Breeders Photon V2+. It will be more expensive than the Current Orbit because it uses 3 and 5 watt Cree and OSRAM leds rather than cheap 0.3 to o.5 watt leds.

Starting a 40 gallon reef tank
So I am pretty experienced regarding freshwater tanks and have been doing some pretty cool tanks for a while. But I recently bought a 40 gallon tank and decided that I want to try something new (I know saltwater tanks are a whole nother beast). So I am starting a reef tank and for the past week I have been vigorously studying reef tanks but I still feel like I don't know enough. I don't really want to spend too much on lighting and im seeing that a lot of the lights are really expensive. Does anyone recommend any cheaper lights?
Thanks so much in advance!

I'll assume your 40g tank is a standard 36" long version. And that your plan is to keep corals as well as fish (corals make a huge difference in how much light you need).

You can get any number of t5 fluorescent fixtures and I'd recommend thyou conside at least a 4 bulb version. These have been around in the saltwater aquarium for many years. Or you could use the newer led lights which have come down in price and are fairly compatible to t5's in cost. Google Mars Aqua (probably selling on Amazon). Their 165 is about $100 and you'll likely need 2. They also make a 300 version that is 32" and still about $200. If you really want economy and are willing to have slightly dimmer light at the ends of the tank, you might try this unit.

https://www.amazon.com/WillsLed-Aqua...W6WA26EAT4YHS1

It looks like most other Chinese black box fixtures, but it's a different shape. At 21" it will probably leave the ends of your tank dimmer, but you probably won't have coral out there anyway. And it's only $79. I don't know of anybody who has used this brand before, but the Mars Aqua has been around for more than 3 or 4 years and lots of reefers use them.

I hope that helps some? Good luck with your foray into the world of saltwater. It's really not as hard as it looks, but it can be quite expensive. If your budget is really tight, you may want to do even more research.

Getting back into the game after being away for 15 years! This thread has been super helpful - when I left, LEDs were just starting to come around.

How well do the Mars Aqua fixtures stay level when you have them daisy chained? Seems like you'd need to zip tie up the power cables, too? I'd like an open top on the 90 gallon, but that requires two of the Mars Aqua 24" fixtures... so I'm probably looking at a hood.

It can be hard to keep any led fixture level when they are hung rather than hard mounted. You might look into doing a DIY pair of flat bars that could go between the 2 fixtures and be held in place with the threaded mounts that stick up off the top of the fixture and then tighten down with the hangers themselves.

Fantastic input, thanks Ron!

I may end up pulling the trigger on the 48Ē Reef Breeder system - itís much slicker and higher-end looking if I do end up going without a hood.

Definitely want to run some sunrise/sunset programs - so looks like thatís the way to go instead of the cheaper units?

That would be an excellent choice IMHO! I have Reef Breeder Photons V2+ over both my tanks. I can't say a single bad thing about them. They make great light, are very controllable and run very cool. As far as I'm concerned, if you want an led that has sunrise/sunset and 6 channels of color control, these ar by far your best bang for your dollar.
