Lighting for a 20Gallon?

do PC's create much heat? i know PC's aren't good fixtures and people prefer T5 or MH but i'm not looking at high quality for this tank and don't want to spend a whole lot, especially since all i want to grow is weeds that can grow under pretty much anything

 

T5's. You wouldn't need like a nice tek or anything, but a 2 bulb T5 will give you what you need.
T5's in the long run will be cheaper than PC's. T5's are more energy efficient, have cheaper bulbs, and the bulbs last twice as long.

 

I would like to try the metal halide pendant with the 2 t5s at aquatraders its only $99. Why not give it a shot it has good reviews.

yea 2 bulb fixuture is what i was thinking. Do you suggest any kind of brand that's not to expensive?

 

only worry with MH is heat and i just worry about odyssea brand

 

For the price I have heard good things about the Nova's and Sundials. They are not the best out there, but at least they don't have the reliability or safety issues of oddysea.

 

Well from what I have read they have improved alot and you could just get a fan to blow across the top of the water.

 

I like the t5s cause they give of not that much heat and about the aquatic life there pretty good cause i have one myself but just with a timer. the bulbs arent that good but always replacment bulbs

 

they are not high end lights,but i personally beleive the issues they had are behind them,you do pay for what you get,mine get warm,but not hot,i also have cooling fans built in

 

Hmm thanks all for the help. I still have a few months before I'm ready to buy the light but at least these options give me a starting point
