Having a little problem with algae you might be able to see on the right side. Although the plants are growing quite well.
I wacked back both the Amazon Sword and Lilly to keep things balanced and not over shade everything else. Very happy how the crypts are coming back and the chain swords are trying to take over the world.
So why so much algae?
-Light = GLO 24W x1 T5HO 18" off substrate, 8hr/day
-Pressured CO2, Plants pearl every day
-Plenty of surface movement and most the algae is in the corner with good water movement
-Dose one pump of Pfertz daily of N, P and M (was told not to worry about K as not enough light and there was enough K in the N.)
-Dosing 20 ml of Excel daily to help with the algae.
Is this skylight giving more light than I thought even with it covered. I have my office lights off for this picture but it is not as dark as it looks. In fact there is enough light to work comfortable with out the lights on.
