lighting help needed

Hello everyone, I have finally upgraded the lighting in my tank to the AI prime HD. I have had it running for a few weeks at low settings so I don’t bleach my existing livestock. I am being gifted a christmas tree rock which is porites coral with bismal worms living in it, so that would be my...

I'm moving soon, so I've taken both of my 120 gallon tanks down, however, in preparation for the re-build, I want to get one 48-inch light to go over each tank for more complete coverage. With my current lighting, I'm not getting full coverage (Got some dark spots). So what are your...

Hello everyone!! this is my first post here. I have a 75 gallon reef tank that has been running for 3 months. There are no fish in this tank yet but there are 10 hermits, 10 nassarius snail, two mushroom frags, GSP, and two zooanthid frags. The lighting on my tank is a 48 inch Coral-Life HO T5...

Hi all, Need a quick help on T5 lighting. I am very newbie , just started my tank 2 months ago, it's a 75 gallon with 20 gallon sump. I have current USA orbit Marine 48 inch fixture. Seems like there is not enough light to cover the tank and I was thinking to go for an extra T5. ATI T5's are...

I just had a random thought/question about lighting and please correct me if I’m wrong: Let’s say that your tank’s chemistry/flow and everything is on point. Will having a longer photoperiod of LEDs that don’t have the best PAR/PUR do the same as lights with high PAR/PUR lighting that is only on...

I set up my new tank in April. It's 8x2x2 = 240g with basement sump in the basement. There is a full build thread in here as well (https://www.reef2reef.com/threads/new-tank-build-for-a-new-house.322041/). On the recommendation of the person I retained to build and install the tank I went...

Friend is coming to help hang lights (2 x XR15's) tomorrow. Question is how high should I hang them? BRS lists the recommended spread for this light as 18" x 18" and I have two, but that doesn't help me decide how high to hang them, right? Do I need to have a PAR meter to figure that out? Is...

I'm looking for insight on lighting for my Tank: 12.75 in L x 48.5 in W x 25 in H. It's a 60 gallon. I'm new to saltwater and want hard and soft corals to grow in this tank. Prefer not to spend over 350. I'd prefer something that's not noisy or super wide. I've looked into getting a fluval t5 ho...

I have just bought a 4 foot 120 gallon aquarium and I need to purchase lights for the tank. This tank is going to be a fish only tank with artificial reef and coral. My question is, what kind of lighting should I get for the tank? I really want something that will make the colors in the tank...

Trying to decide on doing two used radion xr30 pros gen 3 or better to go with two brand new radion xr15 pros gen 4? Planning to run one of these options over 30x32x14 frag tank It's going to be SPS dominate but also will have some lps grow out to frag up.

Curious if anyone has/had experience with the Current Orbit Marine LED(any length). I will be getting a 72" tank 125g and need a decent light that wont cost an arm and leg. This seems to be the best compromise between price, coverage, controllability and reliability. Any light spectrum charts...

I posted this in another section but am not getting as much attention as I hoped. I am starting a 72x18x22 125 gallon tank. One problem I am running in to is finding a light source to cover 72" of sand. I've decided for now that I want to go with possibly 2 or 3 Kessil"s. My question is would...

I am starting a 72x18x22 125 gallon tank. One problem I am running in to is finding a light source to cover 72" of sand. I've decided for now that I want to go with possibly 2 or 3 Kessil"s. My question is would the maximum spread of only 60" be sufficient or should I really consider spending...

Been lurking for a while now but made the decision to finally join. I am in the midst of planning out my 125g tank. I've decided I want to go with LED's due to controllability, heat, reliability and functionality. My question is what's the best LED fixture for the size of my tank that wont cost...

Hello everyone! I have a well-established IM Nuvo 40 that is predominately LPS/Softies with a clam and some RBTAs. I have had a Chinese LED fixture over it for the past few years and it's decent, but I would like to upgrade. Historically, I bought a Halo pendant, but didn't like the coverage...

So I decided I want a single Ocean Revive t247 but am unsure how it would look on my setup. I have a 29 gallon bowfront aquarium with mirror background. Problem is, the light would be directly above my support bar thing on the top of my tank. Would this bar create a shadow with the Ocean Revive...

Without switching to a full hood gut lighting system ( nano-box/steve's ) does anyone know of a good way or if it's even possible to supplement the in-hood Biocube 32 lighting this way ? The lights are okay for what's in the tank now and they're doing well, but if I can easily add some sort of...

I have been out of the saltwater fish world for over 10 years and I am now finally back. I have purchased the Red Sea 525 XL Aquarium and now looking into lighting and a skimmer. My ultimate goal is to have a mix of corals and fish. I am not looking for the best of the best right now, I just...

Hey everyone, I'm new to the forum. I purchased 2x SunSpect 165W LED fixtures with 90 degree optics probably around 6 months ago now. The fixtures are hung about 5-6 inches from the water's surface. I'm having some trouble dialing these suckers in and would prefer to avoid dishing out 100+...

I have a 75 gallon mixed reef tank and I'm looking for a new LED light. I plan on using two 16" fixtures. Which of these two lights would be better? SB Reef Light https://sbreeflights.com/sbox-reef-lights/3-sbox-elite-16-ramping.html Euphotica...

Hey anyone have any ideas as to a good base line for a 24" x 16" x 12" 20 gallon reef tank? I have search thru the web with no real luck. Any help will be great!!

I received my Starfire lighting system from Reef Radiance. Problem is I have two friends coming tomorrow to help me take out previous lighting system from my canopy, and retrofit the Starfire boxes in. My question is how much clearance do I need from the top of thr canopy down to the boxes...
