    Unsure if dinos

    I've had my 20 gallon tank (LS/DR/RODI) for around 2 weeks and I've recently started getting brown growth (with stringly bubbles) on the sand and eventually the rocks. When it just appeared, I suspected dinos so I started overfeeding a bit and removed my chemipure blue. My nitrates and...

    Type of algae

    Hello guys, Can someone help me identify this type of algae? I have been trying and I can’t seem to find something similar! And can algae be the reason why my tank looks so cloudy?

    Web-like Algae

    Hey everyone! I've been reefing for only 3 months now, so still learning a ton, and I'll tell ya, I can't wait until I can sit down and actually enjoy my tank instead of obsessing over learning and trying to figure every single detail when things change. That's a side note though. :p So I've...

    Need help with an ID...

    Well I’m having a little issue. Seems it has gotten out of hand pretty quick. Can you tell what this is from the pics? I don’t see any air bubbles at all, anywhere. So hoping not Dino’s. Was thinking Cyano but chemiclean isn’t doing anything to it.

    New Tank - First signs of Algae

    My new Elos tank has now been up and running with fish for 2 weeks now. This morning I found the first signs of hair algae on the rocks. Is this all normal? It seems to be covering most of the rocks. The rocks (started with dry Marco) have been cycled in a Brute can for the past 10 months so...

    Can I convert cyano to algae?

    I have a tank with consistently high nutrients. It’s not neglected but I do minimal maintenance and for the last while there has been mild amount of cyano persisting around the tank. No algae is growing. I know cyano and algae both thrive on high nutrients or poor water parameters but I’m not...

    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.
