    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...

    What water heater do you guys recomend for my 90 gallon tank. My current water temperature is around 68 F (I currently do not have a heater).

    I've been looking at LED fixtures as well as a possible DIY LED light. I've taken in a ton of info on spectrum, PAR etc. but one thing that I can't seem to find anywhere is information on lumens. As I understand it, lumens are the measure of how much actual light is produced. When deciding...

    I have a basic 110 watt power compact light on my 32 gallon and I want to purchase a new LED light. My question is how many LED Lumens = 1 PC watt. I want to add more wattage to my tank as well as upgrading from PC to LED. Can anyone help in a very simple explanation?

    What would be a good heater for a water volume of about 145-150g? Im getting a 125g with a 30g sump. Also how many watts would I need? Im using 2 with a controller for my 55g w/ sump and they are 300 watts.

    Setting up a 210 gallon tank. The fuge is a 55 gal. My question is what kind of heating should i use to keep tank at the right temp and not get to cold. I would like the temp to remain around 78.

    I bought a 180 gallon Craigslist tank this last weekend and set it all up. It was a great deal and everything was great as the seller said except the MH lights are 150 watt, not 400 watt. It is a 72" Coralife Aqualight pro, which is what I have on my other two tanks and I think it's a fantastic...

    Ok, So i just set up a 55 gallon hexagon tank. I am planning to keep mostly SPS. i Got everything ready except for the lighting. although its a 48" long tank, I either have a 48"X8" or a 32"X14.5" area to work with within the canopy. Right now i have a cheap MH that i had on my old tank. I...

    What's the point of the watts per gallon rule? What happens when I have a 33 gallon long tank and I want to only have corals in the middle of the tank? If I have so many watts per gallon but not enough for a high light coral, couldn't I just move it closer to the top of the tank? Deep tanks...

    is this a good deal?: $60 for a (2)39 watt T5HO fixture, 6 blue leds(forgot to write dn the brand; solaris- something?) BUT: is it enough for a 20" deep 38 gallon reef (LPS & softies) Right now we have 2 x 96 watt PCs, and everything is growing well. The idea of being more energy efficient is...

    Ok this is a very confusing topic with all the different types of light out there i think a lot of us need help especially when everything revolves around making money any more. there are three things to pay attention to right, Par, kelvin or color temp., and watts which i don't think matters...
