Metal Halide - can you have too much light ?
After working out that within 12 months of use a metal halide will be
cheaper and more effective to run then the fluro system I was goign to
My question to you is can you have too much light ? My tank is 200 Litres
and is a 3ft tank and the metal halides I can get are 175 watt or 250 watt
for exactly the same price ? Will the 250 watt be overkill and are there ill
effects from having heaps of light ? What should I do get the 250w or 175w
(I dont think I'll get either till ive done some more research and heard you
Another concern of mine is its from a hydroponics shop and the tubes they
come with are rated at 6200K.. is this ok for planted aquarium or do I want
to try and see if I can find something closer to 5000 K ?
Looking foward to your responses and cant wait to have that metal halide
setup when I reach a knowledgable decision :)
Thanks a lot
