I'm worried something stupid might happen with my RO system because I'm positive houston water is filled with copper from our plumbing.

LEDs seem like the Hybrid cars...They are more efficient, yes but the regular gas cars cost so much less that they are the best still.

Will LEDs grow SPS corals? If not, then absolutely no reason to not go PC here with such a small tank.

You could build your own LED driver and save even more money. They arent all that hard to build either. Just a constant current driver that can put enough voltage across your LEDs to forward bias them. A beefy voltage regulator could be used. Some capable of several amps of current draw with a 37v operating voltage.

EDIT: Doesnt 6500k grow algae like nothing else? Seems to me these LED setups will likely have algae problems to deal with. Might just offset the benefit to having LEDs...

Out of all the options, a PC light would be better? I really have to disagree. While its true, not much is known about LED's several things are known. When you do it right, you get about the same PAR as a HQI bulb at about half the wattage. They also have a lifespan of 50-80,000 hours or something before the spectrum shifts. Even at the low end, that 13 years of 10 hours a day. In the same span you would have to replace your PC bulbs over 75 times at 20 dollars a piece. yikes. Not to even mention how much they save you on electricity.

LEDs will grow just about anything, again provided its done correctly. Not to mention when he is done with this tank, he can pop off the LEDs and carry them over to a new project with ease.

I'm not sure about the LEDs in that package, and i havent looked at the spectrum chart in awhile, but i know they are not yellow, and do not grow algae like crazy.

Seriously? You might want to get an actual tank up and running for a year or two, then you can tell us all in your vast experience why float hydrometers are better.

id honestly want to see more success stories before i sink this much into lighting when i could get something alot cheaper and know it works for a fact

Yikes copper in the water? I wonder if DI resin will remove it? If so, better add a DI filter to the RO system...(easy to do).

As for the LEDs, some of the referenced LEDs stated 5000k (YIKES) to 8000k as the possible range. Thats a terrible accuracy. Id sincerely hate it if I spent $200 on LEDs and got some that were 5000k...I think I would poop myself in a fit of rage over that. Seems better to make certain you know the exact color temp before handing over money like that.

As for LEDs reducing algae, I dont see how they could do unless they are guaranteed at a specific color temp. I dont think algae grows well above 10,000k. Maybe if you got true 12000k LEDs it would stop the algae from getting the light it needs? I think t5, PC, and MH all produce some amount of various color temp. besides the main one speced. That may be where the LED has the advantage as they are SUPPOSED to be monochromatic.

I would have to agree that t5 would be a great way to go here. PC would be easier and likely a bit cheaper. LEDs would be the hardest to use and cost much more than anything else (MH included).

That should be enough to get you started. I have about 50 more bookmarks if you insist.
