and maybe LPS
.. what would anyone suggest lumen/watts for a 55?? I know google would be a refremce but who better to ask than other salty divers?!?!?
Lumen is total amount if visible light and watt is a unit of power. But your question was what light to go with for a 55g? Depends on budget, metal halide will work but you pay over and over again on the electric bill and bulbs, T5's again bulb cost, so in my opinion, LED
is the way to go now. They are cooler, cheaper to run and have advanced significantly.... I have clams, SPS
all under LED
. Started with T5's and wasn't impressed with coral selection for my tank. Will cost upfront but it's worth it
congrats to your brother!!
