I have a 75 gallon planted aquarium. I am running DIY yeast C02 through an AquaClear 50 powerhead filter. The plants were added about 2 weeks ago and everything looks fine except for now I am accumulating green spot algae on the glass and on some of the rocks/flourite. I am at 78 degrees and water conditions are perfect. I have 11 swordtail at the moment and it is heavily planted. Running 3 power compact flourescents for a total of 195 watts. Actual water volume is about 52 gallons.

any idea how to keep the green spot algae from growing or any fish, etc that may take care of it? I recently added about 50 nerite snails that I had in a 1 gallon tank. Going to see if they help at all..

Please post any ideas. Thanks..

Also, I was running the lights for 12 hours on, 12 hours off with an air pump running when the lights were off. I have cut back to lighting to 8 hours on, 16 hours off in hopes of cutting down on the algae..

any help is appreciated.

Lol patience will reward you my friend.

You are highly unlikely to find any kind of critter that can eat green spot algae. Algae eating fish and snails use a rasping motion with their mouth to get algae off glass, and green spot is stuck on way to well for the fishes little muscles to gnaw off. Your best bet to get rid of it is to be very diligent about scraping it off with a good algae scraper, and then add a few fast growing plants to compete with the algae for nutrients.
