First on the tube colour, on one end of the fl;uorescent tube there will be some data printed; sometimes one item will be the kelvin, like 6500K. Tell us what that says.

On the plants: some show new growth emerging, the one in the back I agree does not. I would just leave it and see what happens. On fertilizer, which is essential here, you said you have Flourite in the gravel. Are you using any liquid fertilizer, and if so, what and how often?

No liquid fertilizer. Any recommendations?
There were no markings on the bulb indicating temperature but it is Cool White. I looked it up and it's supposed to be from 4000K to 4200K.

I saw that earlier link, it is not all that accurate. I use full spectrum and cool white on my tanks, and both are 6500K and higher. The Phillips cool white I have on the 70g is 6500K exactly, the full spectrum happen to be Life-Glo 2 at 6700K (one of these on each tank, plus one cool white).

I would recommend a liquid fertilizer. Seachem's Flourish Comprehensive Supplement for the Planted Aquarium, Nutrafin's Plant-Gro, or Kent Freshwater Plant [not sure this is still available, can't seem to find it]. Make sure you get exactly these names, the manufacturers make several products in these lines, but these named are the comprehensive micro-nutrient supplements. If you are getting more plants as mentioned previously in this thread, this will be essential in my view.

I'll be getting that soon. Thanks again.

These are the only markings on the bulb:

From what I read on several sites those bulbs are 4100-4200 K. That's a little low. I would look for something in the 6500-6700K range. If that's a T12 bulb, you can most likely use T8 bulbs in the same fixture. You can always buy bulbs meant for aquarium use but it's usually much cheaper to buy from a home improvement store. Finding the kelvin ratings on the packaging isn't always easy, so you might want to jot down some of the common companies' kelvin ratings by description (cool white, soft white, daylight, natural, etc.) so you have those on hand when you go shopping.

Aside from that, the intensity is considerably weaker than daylight/full spectrum tubes, by half or less. One of these with a good full spectrum--if you have two tubes over the tank--can sometimes be OK, but I still do not recommend them.

You want a full spectrum or daylight type of tube, as iamntbatman mentioned. Phillips, Sylvania and GE make these, they call them different things--Phillips calls theirs "Daylight Deluxe" and I use them along with others; Sylvania is no longer available at HD in Canada, but they used to have a similar (identical to my eye) type, can't remember what they called it. The kelvin is on the box and it is 6500K, perfect. These tubes are high in red and blue but also green to balance. In my experience they are good plant growth tubes for aquaria. Angel079 has mentioned a GE tube in a couple of older threads, much the same thing.

OK I'm looking online but I rarely see the Kelvin temp so I'll go around some stores on Friday. I found a bulb that's sold in a LFS. This is from the manufacturer's site:

http://www.hagen.com/usa/aquatic/pro...01015910020101

I'll also go around the other pet stores like Petco and Petsmart and home improvement stores and check out what they have. For now, it looks like Home Depot only sells them 10 in a pack.

This is good light but not what I would use with a single tube over the tank. If you look at the spectrum graph (the coloured box) it shows high red/yellow light. This is called "warm white" as opposed to cool white (more blue and less red) or natural white (daylight). Some aquarists like this type of light, I prefer the cooler; studies have shown that plants grow slightly better under cool white and full spectrum than warm white. Hence, I don't recommend this tube over another.

In that Hagen (Nutrafin) line of tubes, they are several types. The best for planted tanks is Life-Glo. It is 6700K, natural daylight with a hint of higher blue. As true "full spectrum" about as close to mid-day sun as one can get. I use this over my single-tube tank, and it is one of the two tubes over my dual-tube tanks. But it is expensive, 4 or 5 times the cost of the hardware store tubes which if you find the 6500K tube will give near-identical light.

Another aquarium store brand if you can find them are Zoo-Med. Made in Germany, they are less expensive that Hagen series, though still more than hardware store tubes. Their equivalent tube for full spectrum is the Ultra Sun at (I think) 6500K. Their Tropic Sun is very close to the Sun-Glo you linked, warm white; I have used it so I know what it's like. I prefer the Phillips 6500K.

These tubes would be fine, except they appear to be T12 (the diameter is the T number and these are 1.5 inches which is T12). These tubes are being phased out in North America because the T8 (smaller diameter) consume less energy, produce slightly less heat, use less gas inside, and last longer before they diminish output intensity, and for our purposes are slightly more intense in light--so the T8 is a better tube. T12 need replacing every year, T8 is said to go three years; all fluorescent tubes diminish output over time so while they still "light" the intensity is weak after the afore-mentioned periods and they should be replaced.

My HD here is changing to T8, the last Phillips tubes I bought are now T8 but only in 48-inch, the smaller tubes are still T12 (getting rid of stock I expect). If you go into the store, they may have T8 and singly rather than packages; I buy them in pairs which is one way they have them here as well as boxes of a dozen (more for contractors etc).

I bought a pair of T12 6500K Phillips bulbs. Plants should be here by next week.
