Plants not growing? Asking again!?

Problem: Bought anacharis and planted them to fish tank a week ago but there are not growing and look unhealthy (yellow leaves, leaves falling off, etc
Facts
-15 gallon fish tank
-Had tank for a year with fish
-15 watts fluorescent lamp made by All-Glass Aquarium
-I have 4 goldfish (tank overstock but goldfish were a gift. I didnt buy them. dont blame me)
-2 apple snails
-Do water changes weekly 20-30 percent.
-Filter for 30 gallons with CARBON
-NO ALGAE the entire time I had the tank.
-Light ONLY received from lamp. No window where I have the tank.
-Turning the lights for 10-14 hours daily AFTER getting the anacharis.
-Used fertilizer YESTERDAY, no effect.
-Water is room temp or cold (goldfish)
Hypothesis
-Activated carbon sucking nutrients / lack of iron
-Light not strong enough
-Not enough CO2
Other facts
- Answers must be from ppl who actually and successfully planted in their aquariums. Why? Im getting too many answers that contradict themselves. I dont know what to believe
Answers:
Thanks for the added info. Now that your tank size is specified, I would go with not enough light and/or iron as the major problems.
The fertilizer you bought should have iron as one of the ingredients, so that will help in the long term, but you won't see any results in a day.
If you can, I'd try upgrading the lighting system. It would help just to add a second hood of the size you already use, although this may make opening the tank for feeding more of a problem. Make the new tube one for plant growth or a full spectrum to be sure you're supplying the plants with the proper wavelengths for photosynthesis. Beyond that, there are double-tube fluorescents you can buy, or you may want to switch to a T-5 or compact fluorescent which will significantly increase your light intensity.
The other choice would be to select plants that have a lower lighting requirement. Three that I would strongly recommend are Java moss, Java fern, and Anubias: http://faq.thekrib.com/plant-list.html...
See below for info on plants and mineral deficiencies and their symptoms - the first mentions lack of nitrate as a cause of yellowing, but with 4 goldfish in a 15 gallon tank, I doubt this is your problem:
It looks like everything is good I think your Hypthesis is about for Not enough CO2 or Activated carbon, Nutrients or lack of Iron. yellow leaves is usually the sign of lacking Nutrients or CO2, other than that I think it could be shock. Also your snails or fish might be eating it.
well it seems like you have everything you need for a good grow maybe with sometime you'll get it
When you take medication is it instant and don't the results build over time?
Keep giving the fertilzer and next time I would go with a bamboo plant because they are cheaper and easier to replace. You have way too many goldfish and so they are tearing your plant apart. I would try getting some more light and give the fertilizer two times a week. Add a bubbler if you can it helps the plants alot, I would think that you are getting enought light.
In the end I would increase the food dosage, get a bubbler and maybe find a way to give away your fish. If they are healthy and good looking some pet stores or maybe some of your friends will take the other 3.
Hope I could help!
P.s. don't remove your carbon or your fish will die! The fish need clean ammonia and nitrate free water more than you plants like I said increase iron dosage and see what happens!
All of those things you mention could be the problem,but before you spend a bunch of money,look up the temperature range for Anacharis,plants are really temperature sensitive.
4 Goldfish should produce tons of CO2,so I wouldn't buy a CO2 system.
The carbon might be removing Nitrates and Phosphates if you are changing it monthly,but I don't think it will remove iron.
Here's something to try: get a piece of nice driftwood,find some Java Fern,gently attach the plant to the driftwood.(I use bands made by cutting the feet out of discarded pantyhose,but any thing that's very gentle will work.)
One more thing,I've got a couple of planted tanks,and I've kept fish for nearly 50 years,and I've never seen Anacharis actually grow anywhere but in my outdoor "ponds"(horse watering tanks,buried in the ground.) So don't be too discouraged with your first attempt.
Don't blame the carbon, it has nothing to do with it. With this new information regarding tank size, the answer is fairly obvious, your plants aren't getting enough light. One watt per gallon from an incandescent light is nothing! Get a 30 watt fluorescent light, problem solved. Also, stop adding fertilizer, the fertilizer is going to lead to algae, and you wouldn't want to break your algae-less streak...

EDIT: First of all, a bubbler will reduce the amount of CO2 the plants recieve, therefore, killing them. Secondly, Bamboo isn't an aquatic plant, and will soon rot in the tank, fouling the water.
EDIT 2: If you don't have enough money to support the plants, just get rid of them, or you will continue to have dying filth in your tank.
you can't expect a fertilizer to work in a period of 1 day, that's impossible
you need to keep your water clean, that means 25% weekly partial waterchanges with a gravelsiphon
The carbon has nothing to do with it
Give the fertilizer time to work, at least a week before you will see any changes and improvements
Also leave the light on for 10-12 hours during the day and turn it off for 12-14 hours at nights
you could als give hornwort and cabomba plants a try

Hope that helps
Good luck

well i dont have a succeful planted aquarium but i do have a somewhat succesful aquarium. i recently got a plant too, not sure what kind but its broad leaved and pretty so yea... what i did as soon as i got home is i putt it in my aquarium in a small pot with gravel in it, i knew that some how my fish were going to uproot it and i would never put it back and the plant would die, or the fish would eat the roots.
you could have bought a tropical water plant, but you have coldwater fish, look up some coldwater plants.
the goldfish could be producing to much waste, and thus killing the plant.
they could be eating the roots, i have herd of incedints were goldfish (and koi) just randomly shredding peoples plants...

oh and im glad you put all of your tank info, no one does that around here
