i'm not sure which catigory to post this ? so i'm coming to you. I'm noticing GDA still, after a couple blackout periods decreasing photo period from 11 to 8 hours along with light from 4 t-5HO's to 2 t5's. i've been using a modified EI now for over 9 mo. 50 % H2o changes weekly. extensive questing to achieve optimal co2 which has reduced BBA or (red algea) which i'm still working on with a new entry into the diy co2 mixer, showing promise. my tank is an 80 gal with 68 gal of h2o heavily planted w/some 32 species of mostly very soft h2o plants erios, belem ect.. and seen much change in the last months for the good. my ? is what effect does strong ambient light (from windows) have on a photo period in reguard to the spore known as GDA. in my observation i think lots. what do you and the guru team think?
