LED or flourescent
LED or flourescent
I recently set back up both my 29gal nanos after a long distance move, and was seriously considering converting both to LED.
However, while there is a huge amount of choice available with LED, I wasn't able to find what I thought was an authoritative answer on what type of LED system was best for which corals.
Also, as most people using LED are on DIY systems (and only likely to post their sucesses rather than their failures), its hard to know if I will be able to replicate the sucessful systems exactly. I have just started to see lower cost LED systems for sale (MarineLand, others) so I am hoping to switch out to one of these in a few years.
FYI, as someone else mentioned, NanoTuners does have alot of great stuff including some kits that would make it fairly easy. In the end, however, I ended up just switching to the internal reflector flourescent lamps they sell and plan to use these for the next couple years until the LED situation settles down.
