Would two 55watt PCs with reflectors be enough for a 50 gallon aquarium, the dimensions are 36 * 18 * 18.

Want some nice looking forground plants. are any of the common ones like glosso going to be out of this range?

I am by no means a guru, but I think glosso likes a little more light...3+wpg ops:

2.2 wpg would be fairly decent on your tank. Many people grow plants fairly well with just two 55w PC's on a standard 55gallon tank, which is 21" tall. With a fairly deep substrate (3"-4") your glosso would only be 15" away from the light so you've got an ok shot at growing it, but glosso generally likes a lot more light. E tenellus would be a lot easier.

Personally.. I would go with 2 x 96 watts instead...

If only for positioning of the bulbs...

55 watt PC bulb is 22 inches long.. so it only covers 2/3rds o fyour tank

96 watt PC bulb is 34 inches long... full length pretty much...

That would also give you more then enough light for anything.

I would love to go with Dual 96's but they are a little cost prohibative.

rates from AHS.com...

2x 55 = $65 without bulbs

1 x 96 = $60 without bulbs

2 x 96 = $115 without the cost of bulbs

Now would a single 96 be better than 2 55's laid in an overlapping fashion?
like this (each - represents 1 inch of PC, each * is open space)

hard to say... I generally prefer to have a single tube run the length of the tank so you dont end up with a light "hot spot" in the tank somewhere.

I'm not sure how having the extra foot of CF in the tank would affect heating as well... 2 x 55 watt tubes is about 4 feet of glass vs the 3 feet of glass that a single 96 watt has.

I would go with the overlapping arrangement. This way you could try and grow a patch of glosso in the foreground smack in the middle of the tank.

I am growing glosso in an 18'' deep tank with two overlapping 65 watt lamps. It stays nice and low to the ground and forms a neat carpet.
