Is my lighting safe?
Hey guys, I recently got a 10Gallon and have 3 live plants inside. Today I changed the lights for 2 daylight compact fluorescents. Each have 14watts equivalent to 60watts(energy saveer), 800 lumens, 5000k.
Is this safe or should i remove 1?
Here is a link to the actual bulbs

Seems a bit much for 10 gallons, you will probably eventually get algae/nutrient deficiency problems unless you supplement, you might want to just go with one for a while and see how it works out, plus the added benefit of using half the electricity.

This coming from someone with 1 plant currently so you might want to wait for another opinion.

Hmm that's also what I was thinking so I just got home from walmart and now bought 2 "mini aquarium bulbs" rated at 10watts fluorescent it doesn't say the K, it just says 120v 60Hz 10W 180mA (499)
I hope this is better since the rule is 2W/gallon?

The watt per gallon rule is very very generalized, with such a small tank I don't even thing I would look to it for a guide.

You should first consider what kind of plants you have and what level of light they generally require (low moderate or high as an example).

Next look up those bulbs online and find the K, they might only be fish only bulbs which might not be in the proper range for the plants to absorb the light, I've seen people here say the best is to stay as close to 6500k or 6700k as possible as this so its close to natural daylight which is what plants want.

I'm sure it will be very helpful for who ever comes along if you post what plants are in your tank and what the fish load is on your tank along with the type of tank such as if its taller then the average tank(like a hex tank).

Those original bulbs you posted sounded like overkill for a 10g tank, plus with the color temperature being not quite optimal that might lead to algae problems as well. Who makes the bulbs you have now? We might be able to track down more information on the internet somewhere.

Here are my plants, hopefully you guys can help me identify them since I didn't pay attention when I bought them. Also I think I have the wrong type of gravel for a planted tank? Also here is a link to the bulbs I now purchased from walmart

Not sure about the other the, but the second picture is a java fern. You should attach it to a big rock or driftwood piece. It doesn't grow roots under gravel it attaches to things. I'm not sure how it will do where it currently is. Java fern likes low light.

I have those lights for my 10g. If you take one light out, it will leave half the tank very dark while the other half is bright. So, I'm not sure that this is an option for you... and the lights wouldn't be evenly distributed anyways.

Don't know much about the others, sorry. But I think those lights would be enough if you can keep everything balanced, which might be a challenge.

So anyways, about the gravel. It is fine for plants I believe, but to me it seems like it is not very deep. The plant in the last and third picture look like heavy root plants, especially the last one. Might be ok though. ^_^

I actually have no idea about those bulbs, to tell you the truth. I do have several of those exact bulbs in some of my tanks and they work really well but I can't find anything about them online (they don't seem to appear on Lights of America's website at all). Your gravel should be just fine for plants; heavy root-feeders might appreciate the use of some root tabs, though.
