Light for 5.5 gallon? Lamp vs. hood

I'm going to be setting up a 5.5 gallon planted tank. I'd kind of prefer for it to be lower tech for less maintenance. It looks like my choices are A) Hampton Bay desk lamp (assuming I can find one) with a 27 watt compact fluorescent bulb; or B) standard hood with 14 watt 15 inch fluorescent bulb.

Is the 27 watt going to necessitate serious ferts and CO2?

Someone is selling this Hagen CO2 system on Craigslist. Is that at all better than standard DIY CO2? Would it be a good option for growing more challenging plants in my new "nano"?

Thanks for any input!

yes you will need ferts and DIY co2 with 27watts. i didnt dose or use CO2 for a week to see what would happen and i had a green dust algae and a hair algae outbreak.

you should get the desk lamp. growing plants will be so much more rewarding and will make up for the added effort

I have several 5.5gal tanks. One has this the 12" model while another has a DIY hood I made with the CF spiral bulbs. They both are high light with DIY co2 and ferts. The one with the 70 dollar hood looks more professional but they both grow plants equally well and pearl about the same.

The DIY hood cost me about 20 bucks to make but I can upgrade to two CF bulbs pumping out close to 10wpg in the tank. I think you can get the desk for about 20 and not have to make anything, which would be my choice.

OK, I got the lamp today and, as advertised by all the fish enthusiasts, it was $19.97.

And I learned from some searches here that the Hagen CO2 setup is not really any better than a DIY setup. But I'm afraid I might not be DIY enough to do the Coke bottle sort. So I'm going to sit on it for another day, but at $20 for the Hagen stuff (minus the airline tubing I think) plus three kinds of fertilizer, I might just snag it. We'll see.

Thanks again for the input! I hope no one gets sick of me as I overthink every aspect of this new tank -- I'll try not to ask any REALLY stupid questions.

DIY CO2 is easier than baking!

1 cup o sugar
1 tbsp of yeast
(some people add 1tsp of baking soda i think. i dont, but i still get a lot of CO2 and it starts up in about an hour)
enough water to fill your bottle 3/4 the way
shake it up, cap it, put the hose into a diffuser, and voila!

thats the recipie that works for me in my 1 liter gatorade bottle. lasts about a week. for a 2 liter i just double it and it lasts 2 weeks ish.

and ive seen people running the tube from their CO2 bottle into another bottle filled with just water and then the tube from that bottle into the diffuser.

Hm, I don't mean to jack this thread (doing it anyways, hrhr!), but is there a foolproof way to keep the connection b/w airline and bottle tight? Would I use glue or silicone? And couldn't I just get by with Excel? I also have a HydroII sponge in this 5.5, so I'm not entirely sure how much CO2 would survive even for a minute...

I am using a Hagen system on my 15g with great success, so I'm not against the DIY idea altogether.

i use this stuff i call roof goo(idk the real name ) my dad used it when we put up our metal roof. its like gum that doesnt harden over time. silicon would probably work too.

excel might be better than injecting co2 since you have so much surface agitation, but im not sure so dont take my word for it

i use the Clip on "shop lights" from Ace hardware with a 6500k "twisty" bulb from wal Mart for my smaller tanks. the fixture is like 9 bucks and comes with the cone type reflector.

I will have to dig for the post. But there is on on the web about DIY Co2 that is one of the best. In it he describes how he does it. This is the easiest, most foolproof way I have found.

http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXG849

I tried to find these fitting locally but couldn't. Tower Hobbies is fast on the shipping and the cost of the fitting is cheap. Drill the hole in the cap and screw in the fitting. I use a little aquarium silicone to be sure but it probably isn't necessary. The nipple is the size of you tubing.

this is how i have mine hooked up..



cut the airline diagonally so the hole you put it in doesnt need to be bigger than the tube itself. then, add something to seal it (soft putty, silicon, roof goo , etc) you only need to seal the outside of the cap.
