so the last 3 weeks ive been seeing an increase in green algae on my sand. i dont have a picture of the sand with it on as i am at work right now. but i do have this photo to show you where the algae is located. its all in the middle of the tank between the two pieces of drift wood. i only feed my fish every other day or sometimes ever 2 days ( i tend to forget sometimes) and i also have reduced my photo period down to about 7.5 hrs a day now and it seems to be doing just as well as before when i was running my lights for 10-11 hrs per day. im not home often so the only light it is getting is from my aquarium lights (2 48in t8 6500k) im confused whats going on? i dose half cap of flourish comp once a week and iron every other water change. ive always had algae on my drift wood but that doesnt bother me. i like the way it looks but this bright green algae on my light colored sand is driving me nuts! help? please and thank you.
