    Need ID! Longest Algae Ever?

    I've never seen an algae this long. I'd say the longest strand is nearly a foot. Doesn't appear to be hair algae, more like a weird brownish clearish macroalgae of some sort? It's attached to the clamshell. Trochus and astrea snails simply eat whats growing on top of it.

    Found odd white things on base of coral and frag plug

    When my Torch coral closed up for the night I noticed some odd white growths. (Not the white curly worms... I don’t know their name) but I’m wondering about the larger white tube like things. Sorry for the quality my phone refused to focus on the plug. Does anyone know what these are and if they...

    Scolymia turned brown

    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...

    Advice on fish for algae control

    I have a 13 gallon tank full of zoanthids and some snails and hermits and a pistol shrimp goby pair. I’m looking to add a fish that is appropriate for a nano tank and will help reduce the algae. I wouldn’t say algae is a problem but snails don’t really seem to be doing anything about the hair...

    What type of algae is this?

    I got a rhodactia mushroom and this algae came on the frag. Any idea what this is? I just noticed it. I was going to remove the frag and scrub the algae off. It is stringy and stands up. I tried to remove it with tweezers in the water but couldn't pull it off.

    What is this, and how do I control it.

    I have a grainy green algae growing on my sand and rocks. I can't find any information about this, nor what can be done to get rid of it. I've heard opinions ranging from it looks like a green diatom (which I can't find any info on), to it is a silicate based algae. The tank is running the...
