Re: [APD] Help With My New Tank!! -- or - Bravely into the Shadows
Thanks everyone again for providing me with all this
Now I know this is a kinda crazy question; but since
you mentioned it...
How many white LEDs would be required to provide
enough light for my tank? I know 3 LEDs provide one
watt of output but that is about all...
These LEDs are really cheap (50 for 15bucks) - I
thought it might be interesting to try making a hood
with a grid of these. I have a degree in compsci and
my friend has one in compeng. I'm sure we can rig
something up :)
The other option I am considering is using a few of
the 13watt cf tubes from ah.
I have already laid down the soil and sand into the
tank. I'll try to post my pain or happiness as it
In case anyone is interested I have posted my DIY
Stand build here:
