Lighting...
 
I will have a 40G breeder. I would like to keep softies and an anemone. How many watts of CF lighting would I need?

totally depends on what your keeping, cf lighting would be a mistake, spectrum shifts very quickly and will lead to algae issues, cf will limit an anemone choice by 99% ie maybe a rock or flower anem, seriously look at T5ho, 4 bulb minimum, 6 would be perfect, and on the anem? most people say 6months to a year of stable tank conditions before attempting an anemone, I disagree with that and will add that it takes 6 m to a year for the tank keeper to become stable lol

+1 and when that time comes your going to want t5s at the bare minimum if not halides for the health of an anemone. the softies can be kept under PCs but the nem will take better lighting.

ok t-5's it is stand by for fixture. How many watts of halides would i need for a nem?

fishesfriend 08-06-2010 11:46 AM

can I use a halide flood light thats ethier 500 or 300 watts?

its more about the color temp than watts in salt water from wha ti have been told.... for example 6500K will give great growth but awful color
10000K will give a bit more color and ok growth
20000K will give your great color and very little growth
so its really what you want out of the light and also how "blue" you want the tank to look 6500K is very bright and yellow 20000 is more white and blue
hope this helps some

the 300 watt would work, depending on the type of bulb. just watch your temps with only a 40 breeder and such a hot light. watts, or even more importantly the PAR rating of the light is what counts. for example you couldnt have a 10w 6500K bulb and expect great coral growth, if any at all.

I'm not really knowledgeable about lighting for fish tank. But this thread gave me the light.
