25 gallon

[littlefishie]

A friend of mine just picked up his 25 gallon tank, and he wants to plant it. He'll be using pool filter sand as substrate.
Problem is, his hood came with a 20 watt lightbulb. While I'm sure this is enough to illuminate his fish, I can't see any plants [short of Java Fern, maybe] growing in 0.8WPG.
Any suggestions? He has no problem buying the proper plant-lighting tube, but he only has space for one light bulb. How many WPG would he need to grow most plants, like Anacharis, Rotala Indica, Ludwigia/Moneywort, etc.?

2-3 wpg is your best bet, anything above that will prolly be more than enough.

He's got roughly 50 watts on there as we went and got a new bulb, so this should work well. Thanks!

 

[Silly me]

50 watts sound right.. no need to get anymore..

How did you get 50watts???
I have the same problem as your original post. My hood has 1 24inch light, which means I can only get 20 watts to my 29 gallon tank. I would like to have at least 45 watt (1.5 watt per gallon)
PLEASE HELP

I have a 30 gallon tank .. 90 cm / three foot? and could easly fit four 25w of 74cm each in there..

you cant see on the foto to well but the tube is only 74cm long and a commanly sold 30g tank is 90cm long

so two of these on a 25gallon tank is 50 watts oveer 25 gallon at 2wpg

Yeh, but what do you put them in, my light fixture only holds 1 bulb that is my problem.

you have to buy another starter unit, it is possible to attach one floursecent tube to the other tube with tube holders.

We found a 50 watt bulb that was 24" long at Petland.. no idea how we managed that, but one of my friends there dug it out for us. I think it's a discontinued item. *Shrug.* Just got lucky, I guess.
