I am getting green algae on the side of my 29 gal. Which I know is normal but it builds up in a matter of 12-24 hours! I recently went from a single lamp t12 that came with the tank to my 36" 4 lamp t5 by aquatic life, the lamp is for my 75 gal. That is down right now, I have a 30" 2 lamp fixture coming. Will this fix the problem, or should I get some Siamese algae eaters or what? It's just getting to be a little much to clean it every day.

Which bulbs that you use does play a part in it but not that big of a part.
There are about 4 types of fixtures for that 30" tank so which is it ?
24" or 30" bulbs ? T5HO or T5NO ?
If it is an NO fixture it may not give you any algae problems though you may need to shorten how long you use it each day.
The HO fixture, and more so/w the 30 bulb one, will give you problems/w algae unless
you A have lots of plants and injected CO2(DIY may be enough) or B you cut the light
by either or both of raising it up or shorter hrs of use per day.
Placing window screen between the bulbs and top of the tank also will reduce it.
No doubt you will get many suggestions on brand/type of bulbs so I'll put in my
2 cents and say that if you did get a fixture that takes 24" bulbs you will get good
plant growth and light with as little glare as possible with one each of these.

As long as there is a window in the room without a curtain, the fish need no other
light. You can therefore use only 6 hrs of light from that mega fixture till you new one gets there.

When the plants are growing well it uses up more nutrients. Light drives growth but
it still needs nutrients. Same for the algae and if the plants are getting most of those nutrients...
Also there is the over all health of it all. Poor, unhealthy plants just seem to attract the algae.
I'm sure that we may have someone else who could explain that part better than I can and perhaps they will read this before long and jump in.
I was kinda hoping you had the 24" bulbs as they have lots of variety in those. Most of the manufacturers don't seem to do the 30" ones. Coralife maes a 30" 6700K but never having used it I can't say about it having much glare. I know that Odyssea has lots of glair
as my fixture came/w them.
In case someone talks you into getting an actinic(blue) for whatever reason, the 460nm bulb is better for plants. They do use the 420but not near as much.

Nah I wouldn't go for the actinic, my fixture that is coming is a coralife and I think it is coming with a 6700k and 10000k so we'll see
