I might be exagerating a bit when I said the algae looks like it was pearling... I'm sure the bubbles were from the other plants that drifted to the bar.
but everything -- including the algae-- grew crazy while at 40 - 50 PPM for a half a day.
2 new leaves on the lily and a whole spray bar of algae.

This morning I bumped up my CO2 a tad...
After 12 hours, I found my PH was 6.6 instead of 6.9.
That's about 40ppm for my 8KH.
Everything was pearling like crazy...
I also noticed that algae grew like crazy today as well.
Grey hair all over the spraybar now.
There's also bubbles stuck all over it.
So the algae appears to be pearling too.
So my guess is yes, algae responds to CO2 increases like plants do...

|Rolo||I'm guessing you have DIY CO2, since its easy to adjust pressurized. Why don't you just increase surface agitation to get lower CO2?|

|Wasserpest||I hope that's it... seems like you have the nutrients well under control. And the Glosso needs a lot of light, that's true. See if adding more plants will help. And if you can, post a picture of your tank... sometimes that helps to see problems and find solutions.|

|ghettobanana||I started thinking about this and with 3.7 watts per gallon (per say...I have my lights fixed to my canopy so I don't think there is really this amount of light per gallon) I can't see how this is too much. I think my problem lies in balance. It seems that my CO2 was not in balance with everything else. I am going to go and buy a bunch more stem plants and pray to god. :cry:|

Yes all my plants grow great except for the algae. I am dosing with TMG and some additional Potassium, Phosphate, and Nitrate as needed.
I turned the 96watt off so now I only have 110watts on the tank. I don't know about this, but I am desperate.

Do all your plants grow fast, and look healthy (except for the algae?)
What nutrients are you dosing... traces, NPK?

|ghettobanana||i did have alot until I had to trim the plants back to try and get rid of some of the algae. I still have alot and am going to go and buy a bunch more tomorrow. I have some glosso so I worry that if I cut the lights back I will have problems with this not getting the light it needs. what do you think|

Hi gb, welcome to the Planted Tank!
Your CO2 level seem high, but I doubt that this is the reason for algae outbreaks. There is a lot of light over that tank. Do you have plenty of fast growing plants to suppress algae? If not, you might want to reduce those lights until there is a lot of plants, and they start to shade each other.

I am having major issues with algae and I just noticed that my CO2 was too high. Can this be a cause. I am thinking this cause all else seems normal:
Nitrate = 5.0 - 7.0
PO4 = .5
pH = 6.8
I have a 55 gallon tank with 2 55watt and 1 96watt PC's. I am having major staghorn and some green crap on my substrate (this is kinda new though)
