plants overgrown by ALGEA! =(
this is my problem:

i constantly keep getting algea especially on my plants
i have a 5 months old, 130L tank (AR-620T) with 2 x 18 watts of 7100 k (new bubls)
Therefore i have 36 watts for 35gallons, with about 20 plants in the tank.
should i try using CO2 (using the DIY method)

water tested 06/04/07
ammonia: 0
nitrite: 0
nitrate: 5
ph: 7.2

i already have an bristlenose should i get some otos as well, because the bristlenose doesn't seem to be doing the job!

do you know what might be causing this algea, or do you have a solution?

here are a few photos:

I have responded to a post similar to this previously but cannot find it.

Algae is caused principally by:
1) Overfeeding;
2) Lighting of too great an intensity or
3) Lighting durations which are too great.

I believe that only 1) or 3) above are applicable to your post.

In your case another item which may be a cause of the algae is the the 7100K lighting.
This spectrum of this lighting produces blueish light and the frequency range is optimal for algae growth.
(I have a 7100K bulb in my lighting but I also have 3 other 10000K bulbs).

If your lighting duration is currently greater than 10 hours/day I would try decreasing the lighting duration to this value.

If your lighting duration is currently 10 hours/day or less IMHO (and you may not believe this one) the first thing that I would try is dosing with Flourish (a liquid fertilizer distributed by Seachem).
The above may sound like I have lost it but plants are more efficient nutrient consumers than algae and promulgating plant growth will decrease algae growth.

my light is on for about 11hours, so i will reduce it to 9 or 10

i have used flourish excel before and this does seem to help the plants grow much faster and the algea does reduce, but then comes back in a couple of days... and i do not want to keep adding flourish excel as it is expensive...

that's why i wanted to give c02 a try as my parents can by the yeast!!
lol and it'll be less expensive...

i don't think i overfeed my plants.
i give them flakes once a day, a couple of slices of cucumber a week and some peas as well about once a week

How about shrimp? They are a very low bioload and are great for eating the algae.

An additional two cents worth from me.

Should you decide to "get into" fish for algae control I have had very, very good luck with my Siamese Algae Eaters.

I have seven of these in my 110G tank.

Couple other things to ask. Do you have any direct sunlight on the tank? What else do you dose as far as fertilizers?

I agree, get some amano shrimp--they can take care of algae like nothing else. Also, a $10 bottle of flourish excel has lasted my 30 gallon tank about 2 months so far--and it really helps plants and deters algae.
