    I'll be buying 2 used 600 watt metal halides for my 55 gallon tank... I have 2 angelfish, 10 red eye tetras, 1 rubber lip pleco, and 3 apple snails.

    Can too much light harm my fish? What about my plants (I'll be doing a heavily planted tank)?

    Usually metal halide are only needed for reef tanks. (Correct me if I'm wrong)

    What kind of troubles will I run into? I mean, besides algae? The guy I bought them from said he to leave them on only 4 hours daily due to their intensity.... is this ok?

    I know reef tanks use a different end of the light spectrum then plants do, so it may not do anything for your plants. I'm not positive on this though. ( thinking about the actinic blue bulbs they sell for reef tanks made this thought come about.)

    What kind of bulbs are in the haldes? The bulbs will determine if the light is right for your tank.

    Do you know what light spectrum? like 6500k, 5000k, 3200k? You could do an uber planted tank with co2

    I have no idea... well for now, until I get the money for a planted setup, the lights will be hanging out in the closet. LOL
