the led on a budget

[deadrock]

I mounted the fan and the driver to the top of the heatsink so its an aio, much cleaner this way. And its ghetto mounted for now lol

 

[ailachami]

looks good. where did you get the LEDs from?

 

[dirtefish]

Nice build! Love the color u got out of it.

Glad you fixed the problem
those damned pots can be really flakey sometimes

 

[Zooid]

Do you have any red acans in there? I'd love to see if they maintain their
color with your color combination. Mine faded quickly but I'm only using blues and whites.

 

[deadrock]

Yeah I actully have some red ultras ill let you know

And I. Will continue to update the build half to make it clear as possible

What size tank is this on?

 

[deadrock]

Its a 75g on the right side is a 150w hqi and 2x13w t5's and the left side is the led

 

[projectx]

Oh cool, looks great, thought the LED was lighting the entire tank.

 

[KhensuRa]

So are the leds brighter then the MH and the t5's combined.

 

[deadrock]

Yeah significantly brighter lol . I sat and messed with it to try and make them the same brightness ,the led's are as bright as the halide with t5s at about 60% . I think I'm gonna leave it like this for awhile to really see what is better

Now I have observed the the biggist down fall of led's is that people think cw and rb hold a wide enough spectrum to sustain life

Deep water corals respond better to blue. Shallow water corals respond better to white (which is actually full spectrum). See here for more: http://jeb.biologists.org/content/213/23/4084.full.pdf .

My SPS went bonkers under a mix of cool white, blue and royal blue. I saw a sudden surge of growth and coloration I never experienced with any halides. The turquoise and violet might be a good addition, considering the coral photosynthetic response curve below. The only concern with red LEDs is that any micro or macro algae will benefit.

 

[deadrock]

This is actully very simalar to a graph I found awhile back , I want to put a graph of my own together of the spectrum my led's are putting out but my phones not that smart lol

 

[projectx]

Do you have any picts of the tank with just the LEDs on?

 

[deadrock]

No but ill try to get some tonight

 

[deadrock]

Just checked the temp on my heat sink and cool to the touch not even warm? Lmao what a crazy heat sink
