brown algae

Can someone help ID and let me know what I should do. I have this brown stringy algae on my tank bed, some pieces starting on my rocks and a little on my coral. How do I treat?

Hi there, brand new to the hobby. Bought a 32 gallon Biocube to “keep it simple” but have something fun and new during quarantine. But then when I learned about water changes and water parameters and such, bought the APEX system to automate the tank so I could take good care of the new pets...

shortly after I bought this Scolymia, it started to turn brown in some patches. Mind you, I've had the coral for months now and it hasn't died, but it doesn't look the gorgeous bright green that it did when I first bought it. Can I fix this? I've not had any brown algae issues in the tank, if...

Hey Reefers- Been battling BJD for about 3 weeks now on one of my Australian yellow hammers. It's been slowly losing flesh for a few weeks and looks to be coming to it's last days. This will be the 2nd yellow hammer I've lost to brown jelly. Weirdly enough, it's only been the yellow hammers...

Just finished a chemiclean treatment which (so far) seemed to work pretty well. No bright red cyano and the rocks look great. But, I'm left with this brown algae on the sand which I'm guessing is not cyano since it did not respond in any way to the chemiclean treatment which included a 48 hour...

Hi all. My IM Nuvo Fusion 20 gallon mixed reef has been up and running since its cycle completed in mid-October (~2 months). I have a pair of ocellaris clownfish and a handful of mostly LPS corals. All seem to be doing well. I also have 5 cerith snails which will come into play later. About...

Day 17 of cycle. Tank has a lot of brown algae which I know is supposed to happen. I think I just need to hear it from someone other than the voice in my head. LOL Also, I've read so many differing opinions on cleaner crews I'd love to get y'alls opinion on how many, types and when to add...
