    Unhappy

    I'm going to be purchasing a 20 gallon long tank tomorrow to handle all the new CPs I'll be getting this year (curse this addiction) and I'm wondering what I should use to light the thing.

    I use mostly compact flourescents for all my other tanks and they work really well, but I'm thinking that compacts aren't the way to go for the 20 gallon long. Should I go with some tubes? I was looking at the tube fixtures at Home Depot today and I couldn't really make out which one would fit nicely on top of a 20 gallon long. Anyone have any advice?

    Also, the price of the 20 gallon long was about 38 dollars at Petco. Is this a good price?

    You might want to try this. It produces plenty of light,and is relatively inexpensive.

    You can lay the 20G terrarium over on its side and lay the light on top. This allows for even more plants in the terrarium while also reducing the distance between the plants and the light. Hope this helps. If you have any other questions,feel free to ask them.

    EDIT 1- Each bulb puts out about 10,000 lumens,resulting in excellent coloration in your cp.

    My 20gal is 30"L x 12"W, so I use two 2'-long fluorescent tube fixtures for a total of 80W lighting (4 20W bulbs).

    Hope this new terrarium ends up looking as great as your others! [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img]

    Thanks for all the help guys.

    Hey Chloroplast, would you mind posting a picture of your tank and lights? Did you get your lights at Home Depot? How well do they fit over the top of your tank? Did you have to wire the power plug?

    Why do I ask so many questions in a row? [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_n_32.gif[/img]

    Here's an update on my situation:

    I picked up a 20 gallon long tank at Petsmart today for $25, which isn't a bad deal. I also picked up a 48'' flourescent tube light fixture at Home Depot for $30 (it holds two tubes and it's all pre-wired so I don't have to attach a power cord - I'm horrible with that stuff and am willing to pay a little more if I don't have to wire anything) and two cool white 40 watt tubes for $5. I'm hoping this will be sufficient for my new plants, seeing as I've never really used tubes for lighting before (I mostly use compacts).

    I'll try to post a picture soon so you guys can see how it's set up.

    I would get at least a second fixture. Normal fluorescent tubes have alot harder time pushing the light down to the plants than CFLs do. Fluorescent tubes generally need to be within 3 inches of plants for good coloration and growth.

    Really? That'll be 80 watts of light, which is how much I have on another one of my terrariums, just in compact flourescents instead of tubes.

    Also, I think Chloroplast has 80 watts of light on his terrariums and his plants are sweet [img]http://www.**********.com/iB_html/non-cgi/emoticons/cool.gif[/img]

    EDIT: In "The Savage Garden" Peter recommends that for 20 gallon tanks, two 40 watt tubes should be used. Just food for thought...

    Wow, I don't know about that, my lights are 1 foot away from my plants. (EDIT: I measured It was 13", changed previous statement from 2') Of course I have 6 40w tubes, but I am also lighting a 4'x4' area. My plant colored up within 4 days of having the lights, and keep getting deeper and deeper since then.

    I think you are fine with the 2 tube fixture.

    You could try 2 different color temp bulbs, but this seems to get as much debate as soil mix...
