Question Where do I put the light?

I just planted my new 55 gallon tank. I am using shop lights for my lighting. T-8's. 32w bulbs. 2 fixtures, each holding 2 bulbs, for a total of 4 bulbs. I am using egg crate for a cover on my aquarium. Where can I put these light fixtures? can I set them directly on top of the egg crate? should I hang them? how high should they be hung? I don't want to make a hood... ANY advice is welcome. I am completely new to this. Do you think this is adequate light as well? Thank you for all your help! :)

agreed.

You can set the light directly on the egg crate, as long as the egg crate won't fall into the water with weight added to it. I have my twin-tube sitting right on the glass for the aquarium. you should be fine

on a side note, where did you read that you need 4 bulbs for your aquarium? Most planted tanks will do just fine with half of that lighting, some even thrive with a single tube.

do you know the wattage on each of your bulbs? or what type they are?

congrats on the new plants what kind did you buy? we love pictures!

they are 32w bulbs t-8's... 2 are daylight bulbs so they have a higher light spectrum and the other two are just regular old florescent light bulbs. I added 2 because from everything I read low light=1-1.5wpg and medium light=2=sometimes pushing 3wpg. 62w of light for A 55 gallon tank just didn't seem light enough to me, I wanted at least 1.5, preferably 2. I also read that since they were shop lights and I didn't have reflectors/a hood that I would lose a lot of light "power". I know, I probably looked FAR too deep into everything lol. But it did worry me that it seemed that everyone else's shop light fixture had 40w bulbs in it. I wanted to make up for that. I'll post a pic asap.

I have wisteria, sprite, penny wort, crypt, hornwort, a moss ball, amazon swords, jungal val, twisted val, dwarf lilly, dwarf sword, java fern on drift wood, and i think bacopa. Along with some drift wood and river rocks.

You're fine with just 1 of those lights. All of your plants are low to medium-low light plants.

with 4 bulbs your excess of light is likely to cause problems (probably algae) due an inbalance between available nutrients, C02 and light.

your tanks looks very nice btw

I agree with the others, which is what I was getting at, with all that light, you're bound to have problems, you could try and cut in half, or even quarter the amount of lighting you have.

As I stated before, I have two 32W lights on my planted 55G, all the plants are thriving and doing great...some of our members have a single 48" bulb over their tank.

sik80 brings up a good point regarding the inbalance of nutrients, what is your fertilizer schedule?
