I have just stared a in planted tanks, it is a 36 bow front, gravel, drift wood, and a few plants (not sure of there names). I have a 48 watt t-5 fixture over the tank. will that be enough light for "moderate light needs"?

Yes. How long is the tank?

You'll be able to grow a wide variety of plants including anubias, java fern, bolbitis, wisteria, anacharis, and riccia. You'll have a nice low light tank and won't require additional co2.

I have the same fixture on my 29. No CO2 and very little ferts added, although the tank is pretty heavily stocked. Stuff is growing good, Rotala rotundifolia, java fern, moss, etc. You should be able to grow a lot of medium light plants, especially if you are dosing + adding CO2/excel.

I've been told on other forums that it's too much light for a non-CO2 tank, but it's working fine for me and there is zero algae.

Thanks for the input, it makes me feel a better about buying the light. My next question is what kelvin temp would you use. The light I bought came with a 10000k bulb and an actinic bulb. I know this is a good set up for a reef tank but I did not know if this is best for planted tanks.

The 10k bulb is fine. Supposedly actinic bulbs don't help plant growth; regardless of whether this is accurate or not, I don't like the color they produce. Another 10000k or 6500k bulb would look better. My fixture came with a pinkish "freshwater" bulb along with the 10k. It seems very dim in comparison though.

+1

The pinkish bulb may have been the Coralife Colormax. The bulb doesn't seem at bright, but I like the color it gives to the tank.

I like either 6500k + 10,000k or 10,000k + Colormax.

I assume it's the same brand as the fixture, current usa.

I have a similar "plant grow" bulb in my Catalina Aquarium fixture on another tank, it seems brighter in relation to the other bulbs in the fixture.

My fixture is a nova extreme. I am still trying to decide if I like the blue or if I want to change to some thing else. If the plants will grow well under the actinic I may keep it till I have to replace both bulbs.

I'd go with a mix of 10,000K and 6,700K; it gives the best mixture. Lots of blue light, aka Actinic, will make your plants grow tall and stringy rather than bushy.
