Three years is what Diana Walstad suggests as viable life for a T8, and I have read the same elsewhere--but not everyone holds this view. I have no scientific data either way. Plants are not likely to up and die on the day following the end of year 1 or year 3, whichever, so I would suggest observation. Once a planted aquarium is biological established and allowed to run itself, in a manner of speaking, things remain stable. If the plants after several months or 1 or 2 years begin to show obvious issues, at that point I would consider the light as a probable cause, assuming I had maintained fertilization, fish load, water changes basically the same all along.

I know I keep harping on balance, but it really is the crucial issue for a couple of aspects in planted tanks. Once that balance is established--and it can't occur with constant fiddling over light changes, adding Excel now and then, changing fertilization routines significantly--it will tend to stay. My Echinodorus macrophyllus that is now more than 12 years old would not be in the tank today if it had not been in a stable environment with regular consistent fertilization and water changes.

i read in Bryons sticky that its better to hav 2 lights but the plants will be okay with just one right?

I dream of a better tomorrow, where chickens can cross the road and not have their motives questioned.....Dont worry about what people think, because they seldom do.......If you cant laugh at yourself I'll be glad to do it for you.....stop trying to impress people, they're too busy trying to impress everyone else to notice

You can use one. You will want to stay with low light plants as well. I believe Angel is experimenting with one now. She is using a "sunlight" bulb I believe. You will want a full spectrum bulb or a plants bulb using one. Keep in mind that a plant bulb will likely give a purplish tint to the tank. This is where 2 are nice as you can add a bulb that has a green spike in its spectrum to brighten it up for human viewing asthetics should you not care for the purplish hue of a plant bulb

First thing is to have adequate minimal light for your setup. Some tanks can manage fine with one tube across them (full length), and up to 55g works fine like this; from 55g and up you are pretty much into two tubes. A 55g itself can be either one or two, depending upon the setup and plants.

I have a single tube over my 33g and for the past seven months, with no fish in the tank, it has been full of plants like swords, pygmy chain sword, pennywort and floating plants Ceratopteris and frogbit. One tube, full spectrum 6700K, 25 watts, a Life-Glo 2 as it happens. The last time I had fish in this tank it was planted with Anubias bits that were themselves more than 10 years old, crypts and floating Ceratopteris. A photo is attached of what it looked like then. The point of this is that you can grow a lot of different plants with the same single tube, as long as it is good light. On your 29g I would stay with one tube, and select a good full spectrum (enhanced daylight) around 6500K at whatever wattage fits the fixture (tube lengths are standard wattages in T8 or T12 with a couple exceptions as I think I noted previously in this thread).
