brown

Over 6 months ago I started getting a lot of these particles on the bottom of my tank and sump. I'm not a new aquarist and even this current 400gal system is over 3 years old, but I am stumped on identifying and eliminating this rapidly accumulating brown dusty particles in the sump and tank...

I don't know if these images are clear enough. New Zoa frag in the tank four days. Starting to open, but struggling a bit. Noticed these brown strands wrapped around the Zoas with these little black heads. Are these just zooxanthellae from an acclimating coral or something more sinister? The...

Long story short, no clue what I was doing but amazed that I got some pics. Not sure the magnification is. It's kind of a reddish brown hair algae.

what are these little brown like clear worms? and are they good or bad? Sorry can’t really get good pictures they are tiny.

Hello I added a scopas tang and a midnight angel last week into my tank, everyone was well, and is, my fox face is happily swimming, my claws swimming my cuc cleaning and my tang was very lively too until just 10 minutes ago, I came and I saw it lying flat on the ground, breathing very rapidly...

Hey everyone! Had this tank running since January, and have only just noticed how large these brown algae spots have gotten. They were originally quite small, thought it may be diatoms, but I’ve attempted to take the rock out and scrub them off, as well as peroxide them, but they stay...

Hi all, I’m new to the site and semi new to reefing. I’ve always taken care of Discus and African cichlids. I still have a fear of putting in corals but hopefully this forum will help. I just have a bit of concern with my newly acquired Bangaii Cardinals. One of them has a brownish...

Hello, I’m newer to saltwater tanks and have absolutely loved everything about it. I’m having trouble, and could really use suggestions. I have a Waterbox Cube 10 that is going on 3 months. The tank currently houses a clown, purple fire fish, shrimp, mini conch, and 2 turbo snails. Levels...

Can any one id this anemone

I have this fairly nondescript 5-6" Chalice. I saw one similar/same to it in some YouTube tank video panning across that didn't say anything about it, but don't remember who. Under normal lighting conditions it's fairly basic brown/burgundy'ish with white spots. Under blues it starts to...

Hi all I’ve been fighting this stuff for a while now and can’t figure out what it is it’s wavy and comes off pretty easy

Hi all! Yesterday morning I noticed my foxface had a large mark on its right side that suspiciously looked like a blenny kiss. After looking at the forum, it must be. I got home in the afternoon and noticed the Fox now has a Brown ring on the same side as the blenny kiss (blenny kiss has faded...

Hey folks This will not be a new topic, but I need ideas. I have a Waterbox 130, running 8-9 months now. I have big Acropora dreams for this tank, and it was going well there for a while. Growth, color.. but then everything seemed to stop on me. Acros went brownish, polyps are unhappy. Nothing...

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...

Softies and everything else seem to be OK, but hard corals (SPS, monti) just brown out within 2 weeks of putting them in. My nitrates were high (60) for awhile but I've brought them under control (10). Lights are mostly blue at this point, no white, red or green (AI HD26). Any ideas? It's...

Hey guys! So two days ago my weeping willow toadstool looked normal and happy as can be. I did a water change and now today, it has this brown spot on it. That is the only change that has occurred since. Other corals are looking perfectly fine and fish look good too. I don't know if it's just...

Hey #reefsquad, I noticed my grape coral frag had some of this brown algae stuff growing on it. It doesn't seem to be getting any better so I was wondering what I should do??? Nervous that it will spread to neighboring torch corals so please help!! Thanks so much!!

Hello folks! I got this acro from a friend. It was completely brown and so far has not shown any color. What kind of acro is it? Help me with the posible ID. Thanks in advance!

Hey there Long time reader, almost first time poster. I've been keeping marines for about 6 years now, and one thing i've always struggled with is SPS colours. My latest tank, a TMC signature 600 has been up and running for 2 years, and is mainly SPS based. I should say, my other corals are...

These guys on the rock survived the phosphate crash, came back to life, but have lost all color. Other palythoas I have still have their colors. What should I do with them? I don't even remember what they originally looked like, part of the 2nd rescue tank I think.

I spotted this 'thing' and I have no idea what it is. It is growing in a couple different spots on this particular rock, the one pictured is by far the longest. It is slightly translucent, brown in color, ugly as sin.

My entire life I grew up in a muted world. I grew up in a brown brick house, didn't understand why street signs were so dull, and never understood why people were confused with my fascination with neon colors (neon pink being my favorite). Then one day while at the doctor's office it all made...
