cloudy new aquarium and low light

Hi,

I picked up a used aquarium, 75g with a penguin 330 filter, and a light hood
with two 20 watt fluorescent bulbs. I bought new bio wheels and filter media
as they were missing. I have two plastic buckets things in the back that are
empty though what should I put in those? I also got an air pump and a 48"
bubble bar. I bought 65 lbs of the epoxy coated gravel. I rinsed it in a
small bucket a couple of times before putting it into the aquarium, it
didn't seem like there was much debris aside from chunks of plastic that was
not attached to rocks. I put the gravel in the tank along with a few
decoration and filled it up with water. Then I treated it for chlorine. It
was a cloudy when I filled it up. I assumed this was dissolved gasses and
that it would fade away, or that it would settle.

The biowheels don't turn very well, but regardless the filter makes a lot of
small bubbles which I can see. The tank is still pretty cloudy when I look
at it from the ends, but it's almost clear when looking at it from the
front. Will this eventually clear up on it's own or is there something that
I need to do to make it clear up?

I have been reading this forum for a few weeks to get up to speed on
aquariums, I haven't had one in several years since I was a kid. So I went
out and got some cycle by Hagen, and 8 danios and 6 glo light tetras to
start my bacteria cycle off. The ph of the water here is around 7.8
according to the city. I tested mine and it was 7.6 in the tank The ammonia
was .9 and the nitrites were 0 after 24 hours. One fish died so far but the
others seem ok.

I was wondering about the lighting as well. I assume that 40 watts of light
is not enough for live plants in a 75g tank. My tank has glass tops, the
larger piece of glass is about 9" deep with a smaller liftable lid in the
front and a slot in the back with some plastic. It's possible I suppose that
I could put a second tank top light on it, it would be a tight fit as the
light I have now is about 4.5" wide. I was looking at petsmart and it seems
that they were wanting 78$ for a light hood. That was sounding pretty
expensive to me for a fluorescent light. Are there any inexpensive
lighting options or should I just buy a few plastic plants?

Thanks
