i have algae of every sort it seems. And the only reason i can think is because my aquarium is in a room of all windows. i know, i know...keep aquarium out of direct sunlight...but this is not an option because this is where i want the aquarium. so, since it's my choice to keep the aquarium here, i need advice on how to keep ahead of the horrible algae. I've got it growing on the sides and have been using a tooth brush to brush it off, but i think i'm going to try a razor blade which will hopefully be more affective. I've got all kinds of plants growing that i've been picking off rocks with tweezers, but I can't keep up with them, so any advice for that? I started doing weekly water changes thinking my ph and nitrates were maybe a problem, but this has made no difference. I'm not using ro water, i'm using my own filtered water. and it started spreading like zombies ever since the weather got nice, so i know it's the sunlight. I just need to know how to get either ahead of it so i can keep ahead of it, or in control if possible because my tank looks like crap no matter what i do. please help!
