I happened to find this thread and have been reading through this. There is a lot of pages lol, but great info. I have a 20 gallon long. I have a glass top and my light is set above my tank about 5". I was dealing with some algae, which is getting better. I am dosing every other day with easy carbon. I don't use CO2. I am trying to add more plants to help outcompete the algae. I have java ferns, Anubias, Buce's and stem plants. I also added more flow. I watched Bentley Pascoe's youtube videos and set my light according to his recommendations, and started ramping up slightly each week by a percent or two. Right now I have my lights set for sunrise for 1.5 hours, blue at 2% red at 15% all the whites at 25%. sunrise is at 10:30, lights 12:00-18:00, then sunset for 1.5 hours. I was playing around with the whites today and realized I don't really like the warm white. Can I omit the warm white and just use a higher percentage of the other 2 whites? Instead of 25% each white can I do 50% of the pure white and 25% of the cold white? Today I changed my sunrise and sunset for 2 hours each instead of the 1.5 hours it was.
I was also reading about a dual siesta lighting schedule but have no idea where to even start with that for my 20L. Can anyone suggest settings for a dual siesta for me if I decide to try that?
Thanks for all this great info and this very informative thread.
