I've decided to switch fully over to T5s on the 55. Just bought the ATI dimmable Sunpower fixture. My question is on bulb replacement time. Does a quality fixture extend bulb life? I've read of some people using this fixture using bulbs for 18 months. ATI claims "Superior design and high-end...

My first post, how's everyone doing! Yet another "which bulbs" question. Currently have a 36" Aquaticlife 6 Lamp T5-HO fixture. The fixture is about 4 years old and i'm ready to replace the bulbs (quite overdue, i know). Looking for specific recommendations on which bulbs to use. For anyone...

Hello All. Still planning my tank relocation. Concerning lighting only for my 75G DT: I currently have (2) Ecotech Radion XR30 Gen 2's and was never impressed with my coral coloration. I plan to build a hanging canopy to house the Radions lengthways of the tank and add (2) 48" 2-bulb T5HO...

Hey everyone, I'm looking to replace my bulbs and i noticed that there 46" not 48" I have 2 marine glo bulbs and 2 power glo bulbs in it now and I am looking to switch to ati or something like that. Is this the normal actual size of the bulb or do i have an odd fixture? Thanks

Hey guys! So a friend of a friend had to pack up and move out of town with little warning and decided to sell his whole 180 set-up DIRT CHEAP to us because he didn't know half of what he had or how it worked and knew we could "enjoy it." (For the price he sold it to me, I'm ecstatic!) The...

I was just wondering if anyone had any information on T5VHO bulbs. Can't seem to find much info online about them. It seems that the VHO bulbs are more for the T8 style. Does anyone have any info on these? Maybe some first hand experience? They should utilize the same ballasts as T5HO correct...

So here goes another (more than likely) ignorant question. I have a T5HO Quad Coralife light with lunar directional lights. It came with 2-54W 10,000 daylights, and 2-Actinics. Now my question is what bulbs should i replace these with? I hve heard the ATI ones are very good? As for the corals...

I had some issues with corals bleaching, so I started testing my water.. ph, mag, dkh, cal, etc.. everything has been in acceptable ranges. The issues started when I replaced my bulbs in my ATI 6bulb fixture. The fixture itself only sits about 2 inches off the water level, and I run 2...

Anyone out there using ATI bulbs? Our plans for SPS tank, along with mushrooms and anemones and we have heard that ATI are the higher quality of bulbs. Right now we have the 48" Deep Blue bulbs that the light came with 4 bulbs at 54W 2 10000K and 2 Actinic. The ATI has a 15000K and then...

Just a quick question concerning my t5 lamp. Its been about a year and its time to change the bulbs. My question is do I have too much blue end spectrum or do I need to a 6500-10k lamp? I have 2 UVL 454's in the actinic slots ($20 for the pair... good deal?) and a Geissman aquablue + (crisp...

Hey everyone! So I found a good thanksgiving day deal on coralife t5ho bulbs, 420/460 actinic and 10K for $9.99. I am already buying a koralia evolution from the site so in addition to bulb saving will also save on shipping. My question is how are these bulbs? I know the suggested best are ATI...

I have two question about my lighting. first- How often is it recommend to change out these bulbs? Second- I noticed that Current USA has discontinued their 10000k and is now using a 12000k bulb. I have two actinic + two 10000k now, would having the 12000k make my tank look to blue?

I have a Nova extreme pro fixture, 12 bulb, and I want to change out the stock bulbs. What are the best bulbs for the price, and best combinations? Right now I have a mixed reef, but moving more towards sps. Thanks
