    Cichlid, I told you the job is at Duke University :P

    Fiesta, the LEDs should have 70% intensity at 10 years. If you keep them cool and underdrive them they should last much longer than that. They pay for themselves just in bulb costs at year 5 (add an $800 fixture to that equation and you can see how the savings really pile up). If you factor in electricity savings (not really a concern for me...) it's probably 3 years compared to metal halide or 4 years compared to T5's.

    okay well what i don't unerstand (electricaly) is if i have 100W LEd setup why would it consume les electricity than, lets say a 100W halide light ??

    Heat and water evaporation = running a chiller and using more water.

    Also, a 250 watt halide bulb is roughly equivalent to 24-30 3W CREE LEDs. So you get the same amount of light out of the LEDs but at a cost of 80-100watts. Now, Wattage IS NOT a good measure of LED quality. Lumens and penetration are.

    Re: New job, new DIY

    That is such a great argument point h2so4hurts, a buddy of mine has 2 250w halides over his 130 and is forced to run a chiller because of the heat. Well, the other day I was suggesting he switch to LEDs. Oh and before I forget, his chiller went bad while he was away, end result, losing 80% of his corals. Okay so, like I said I suggested LEDs and he said, "they're too expensive to purchase" Well this point in invalid when you take into the consideration, buying a new chiller, the cost of running the chiller, buying new halides bulbs every 10-12 months, the cost of running halides, also like you said, the water evap from the heat. I really do think in about a year from now there really will not be any solid reason to run halides instead of LEDs. I know some people say that LEDs still lack in some areas depending on what type of corals. But I def think halides are on there way out.

    The only thing that halides have going for them is that some people think they "look" better (I don't think this, but many people do). Corals don't care where the light comes from as long as you hit the right light range to activate the chlorophyll in their algae.

    I think the dimensions are more important than the actual capacity.

    Re: New job, new DIY

    Again, watts are not a good measure of LED quality...

    What are the length, width, and depth measurements. Depth determines how many LEDs you'll need per square foot of LxW. On a 24" tall tank, you want 12 3W CREE LEDs per square foot. So for my new tank, that comes out to 192 LEDs [(8'x2')x12LEDs]. This build has 216 because I wanted a little extra power Click here to enlarge

    Just do length x width=X then X times 6-12 LEDs. Example, my tank is 3ft x 1.5ft= 4.5ft 4.5 x 8 LEDs= 36

    Don't worry about threadjacking. I'm going to just start a new build thread for each part. It'll be easier to follow that way.

    Your calculations were right!

    But they are the top of the line water movers, and with an 8ft long tank, you need powerful pumps to get water moving at the center. Just glad I could get them for 30% off Click here to enlarge

    Wow for $1000! That is about my total investment in my 125g reef tank and my 55g reef tank combined! I couldnt aford this hobby paying those prices. I have a lot of fun creigslist hunting though and I simply dont buy unless its pennies on the dollar. For example I have never paid more then a dollar a lb for live rock and that was live rock covered with mushrooms and polyps. Anyway not trying to go off topic.

    This is one of those few products that doesn't lose it's value. They retail $750 each... so a grand for two is a steal.

    Re: New job, new DIY

    Acrylic sheets will be ready for pick up next week!! I have two huge orders coming in today and tomorrow.

    The one thing I'm still deciding is how to plumb the returns. I'm going to plumb the overflows on the right side of the tank. Maybe it will turn into a peninsula tank. I just don't want to get into a situation where my bulkheads are backed against a wall and I can't get to them if there's an emergency. But then the return lines become tricky. I'm considering plumbing the returns through the top flange of the tank, because I don't want any pipes going through the bottom of the tank. They take up space and look ugly...

    The calculated head pressure with two 90 degree turns, vertical height of 5ft, horizontal length of 8ft, and 4 exits is just above 2000 gph. That's about right for a 240 gallon tank ~8x turn over (maybe a little too much).

    Re: New job, new DIY

    Think florida...Surrounded by ocean on 3 sides. Same idea for a tank, 3 sides stick out into a room. They're nice because then you can view the tank from the two long sides.

    Yes, the reeflo Dart is a brand of external pump rated for 4300 GPH at 0 feet. The reactors hold Granule Ferric Oxide (binds phosphate) and Pelletized activated carbon (ROX carbon).
