I Have A New Kind Of Algae!
The algae is spreading across the bottom third of the front of the tank. It is brownish, almost invisible but makes the glass look smudgy (no, it's not really smudgy - it's the algae. Promise.) I have the back side blocked out - not a problem. The front of the tank is facing a big south window but it's probably 20 feet away.
I am wondering if the the fluorescent might be hitting it and also bouncing off the gravel. I started fertilizing last week, once, a very small amount. The plants haven't responded majorly. I also added 4 Pristella Tetras for a total of six, but I feed them once a day and very sparingly. They are the only fish in my 10 g tank, plus a population of pond and Malaysan Trumpet snails. The lighting is one 18" 17W Radeon that came with the canopy - I am told the color temperature is 8,000 K, if you can believe that. Water temperature is 78-79F. The tank was started 2-3 months ago.
I really don't want to get into scraping the front glass every time I do a water change, but I would really like some suggestions about how to get rid of the algae. Probably the first one should be, "Get more plants!"
Thanks for the help,
