I have a 10gal fully cycled tank with 4 female guppies (and one lucky darn fry), and 5 ghost shrimp. 0 amm, 0 nitrite, 5 nitrate, temp is about 78F. I am starting to see algae growth on the substrate and some of the plastic plants. My cleaning is not getting it all out. Does anyone have suggestions before this algae gets out of hand. I leave for work about 5am and get him about 5pm, the lights are on from 5am until about 9:30pm. Do I need to turn the lights off earlier and just not enjoy my fishies when I get home from work to reduce the algae?
