metal halides

  1. General Reef Discussion
    Good morning everyone! I am currently running an Coralife Aqualight Pro with 10K Halides and True Blue Actynics. I've been pondering changing up to 14K's to get more of the blue spectrum just for aesthetics. I figure if i miss the more natural look of the 10Ks I can always switch back. What...

    do not get me wrong here. i know that LED's should be the future, but for now they still see way behind MH's in what we need for our reef tanks. what am i missing? they produce less light per watt. it makes little sense to me to replace my 150W MH with a 180W LED, if the LED is producing less...

    I had a 6x39 t5 fixture that I'm switching to 2x250w. Using 2 icecap ballast with 2 20k DE hamilton bulbs. Where should I start to hang and how should I adjust so I can eventually get to 6-10". Seems like overkill for a 40B but I plan on having clams and lots of sps. As well as some Lps at the...

    Anyone know firsthand facts about the quality of these bulbs? http://www.lightexports.com/servlet/the-Aquarium-Lighting-cln-Double-Ended-HQI-Metal-Halide/Categories Even if I have to replace them every six months, that would be 2 x $20 = $40 ....where brandnames like Hamilton, Ushio, Phoenix...

    So I cant afford LED's yet, but I am going to pick up a set of 175w MH's for pretty cheap. I am curious how this lighting schedule sounds? The theory sounds good in my head but no clue how it will work in reality. I have a set 4 bulb T5HO that are 2 Actinic and 2 White I am not positive of the...

    This is my first posting to thereeftank.com and i am pretty much a newbie to saltwater tanks. I currently have a 36 gallon tank but i am upgrading soon to a 60 gallon rimless and reef ready tank. the dimensions are 4 feet long, 2 feet wide, and 1 foot high. i have a sump, protein skimmer...

    Just a quick question, I think. Should my t5 actinics be on at the same time as my metal halides. I start my t5's a couple hours before the metal halides and leave them on a couple hours after, is this correct? Thanks in advance for the response.

    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 have just bought two 175 watt metal halides for my regular 55 gallon. I also plan to use two 65 watt power compacts to supplement this. My question: Is thuis too much light? I do not run a chiller and do not want to run one. Am I going to burn up my corals. Thanks

    so i finally decided to go and try LED's. I found a company that I have already purchased from before when I got one blue LED to get that "glow" look. I've been very pleased with their product so i decided to get more and go completely LED. my question is, i notice a different in the tank I'm...

    My tank is generally in the 76-78 temp range. With the new MH lights I instsalled with the legs it came with, the temp increases to 80 after 3 or 4 hours. I've read the lights should be on (14k) about 10-12 hours for the corals. Isn't 80/82 too much fluctutation and heat? Wondering if its...

    I just ordered my first set of halides :banana: to switch from T5's(I just love the shadows and shimmer) and I am just curious to see what the majority is using these days to power their halides. Are you using traditional magnetic ballasts or digital? Have you noticed any significant...
