Anyone Thinking of Dumping LEDS and going back to Halides

How high where your halides from the water surface. And I know they where no 3 inches. Lets be fair.......................and honest about this.................PLEASE
 
Who says you can't keep MH 3" off of the water level? 2 x 250w SE and 1 x 175 SE. I did cheat a little I had glass tops with a 4" fan blowing across the top. My Office temp was around 73 and the tank 75-76

Alton - what bulbs you got in there? I really like that coloration a lot....
 
Used the cheap chinese LEDs last build. Going old school MH this build. Only way to be sure...

12K reeflux, they lasted about 18 months before each change. If I didn't get the radium fever I would of never changed. If Radium keeps going up I might change back
 
Alton,
Good looking tank! Yea, having the office at a constant 73 degrees does not hurt one bit! And having the lights in a canopy with a fan certainly made a big difference.
Hey, if it's working for you and your happy.....................THEN I AM HAPPY FOR YOU!
All I an say is in my circumstances I love the leds! They are working great and I am growing corals with 95 watts of light! I AM LOVING IT
 
Due to the venting fan design I used it added zero degrees to my water and it sat on the tank.

My first MH generated too much heat, even inches off the tank & I could not use them or else I would kill everything due to heat.

My next MH/T5's were Acquatinics. They were enclosed & plexiglass on bottom & fans on both ends. They sat right on top of the rim of my tank & water temp only raised 2 degrees mostly. On those really humid days, then 3 degrees. So I can vouch for the statement above.

I would have never believed it if I had not seen & experienced it with my own eyes. Even my 150W Sunpods on my 29g generated 2-3 degrees temp increase.

I would call that a good thing, unless you were hitting the upper 80's.

Everyone is so worried about temp swings, yet they are totally natural and happen all day in the wild.

I will say that my tanks with temp swings, have been my healthier tanks overall. I love to see my tank swing 3-4° a day.

The temp swings depend entirely on where you are. out on fringing reefs you will see seasonal swings, but not daily swings. Lagoons can be an entirely different beast.

I don't know that temp swings are either a god or bad thing. It may well depend on what corals you keep.

There's a few studies out there to prove temp swings make corals hardier. I'm on my phone and don't have the link with me right now.
 
Not if your pushing 83-84 in the summertime. Don't get me wrong, I still LOVE MH & the combo of MH/T5's. The only thing I don't like is the 200+ a year I had to spend on the bulbs. Sorry, but that is criminal. Now that a part of the market left for LED's, the prices will more likely go up higher.

I never had a problem with heat or energy cost. I ran my MH for only 8 hrs.

I paid $254 for 2x Chinese LED's......almost the cost of my bulb changes in 1 year. That is sick man, just sick!!!!!

The energy cost coupled with bulb cost is just too enticing for me. I will try & post a pic of my tank today. I tell you what, if the lights don't work out for me I will gladly come back & renounce LED's. I will make a video of me throwing them off the roof & post it in here. I will become a MH Fanboy again!
 
83-84 is a normal temp for most reefs, warmer than a few but colder than most.

Here is an excellent thread, pay attention to greenbean36191, he is not just a hobbyist, but today is a scientist who has spent many years measuring reef temps around the world as well as other worthwhile projects.

With all the water i have in my garage here in southeast texas, i didn't have a chiller the first year and my tank was at 84 in the summer. No issues.

i did get a chiller the following year for peace of mind.
