We are talking major algae bloom in all cases where photo-period exceeded 8 hours and light intensity exceeded 2.5 watts/gallon(equally good results were obtained with 2.0 watts/per gallon with all other things being equal). This happened even in tanks that were jam packed with plants, which kind of surprised me. |
I been reading up and when your plants start to close up shut the lights off. They had their photoperiod. The rest of the light goes to the algae.
