Hello, I'am a newbie here and found this thread to have a lot of good information. Thanks
My tank is a 150 gallon with fish, a few corals and about 150 lbs of LR. I also have a 30 gallon refugium
I do have a small issue with some random green hair algae patches. It's not long hair or really taking over the tank and it pretty much came out of now where. I thought perhaps the lights were needing to be replaced as they were getting close to a year old. (T5's) so I replaced them then went thru a 3 day lights off session which helped a bit but not fully. I have been watching my feeding amounts also. I have added about 100 red leg hermits and about 100 cerith (?) thinking they would help. This stuff is more of a nuisance than anything, I have cleaned the powerheads and some of the rock that it's growing on when I do water changes thinking that'd do it in. But noo.
So here I am looking for ideas, TIA for any offered help.
