    Bacteria? Algae? Rip clean didn't fix it (need help)

    Hi! I have an IM lagoon 25 that has been running for about 2 years now. I have this weird fuzzy growth on the rock (for about 6 months, doesn't go away on its own). It only grows in the light so its photosynthetic. It has a brownish tinge to it but also can be closer to white. It doesn't grow...

    Dino X and Cyano?

    About a month ago I determined I had a Dino outbreak. Started using Dino X and now after 6 doses my Dino is fading, but now there’s a thick maroon algae building up. I believe it’s cyano. Has anyone had this experience?

    Brown stringy algae on rocks

    I’ve noticed this type of algae that has rapidly starting to grow on the top of my rocks. Tank is almost 6 months old. Phosphates: 0.05 Nitrates: 5 Could I get an ID? And possibly a cause and a way to get rid. I’m also adding a new lawnmower blenny this weekend after being quarantined for 6...

    My Easy approach to Amphidinium dinoflagellates

    I have a 50 gallon cube, sump, sand, ATS, radion LED, Protein skimmer, my aquascape is fairly easy to remove in sections. My troubles with Dinos coincided with overzealous Iron supplementation and low nutrients. I lost many corals and anemones to the infestation. I am not sure if my approach...

    ID This Snot Please?

    Have some snot on the back glass, that's growing in an interesting pattern. It's ONLY growing on the glass, and both the turbos and nerites are eating it, so I don't think (fingers crossed) it's dinos. Some of the strings are nearly a foot long, but no bubbles. Where it's growing best is on the...

    Ultra life blue green stain remover

    I just purchased this to treat my reef tank but now that I read the pictures it doesn’t say reef safe, does anyone know if this is reef safe or safe for corals? I have used the red slime one but not this one I don’t know if it makes a difference or not

    Another Algae ID Thread

    Yet another person in need of an Algae ID. I have reviewed things online, and I'm just not skilled in the art of ID apparently. I do have a microscope, but I'm not sure what areas need to be photographed that would help. So, here are some in-tank, on a white paper plate and then under a...

    Advice on hair algae with undetectable nutrients

    Hi guys, I have had 0 nitrate/phos for a while now (salifert kits). It lead to a pretty messy Dino outbreak, I'm pretty sure I have now beaten the dinos through a combo of Refresh/waste away, siphoning through a filter sock, running only blue lights and HEAVY feeding. I have a 56G tank, and...

    What are these white round spots spreading across my live rocks?

    My tank is newly cycled. Sat up 2 weeks ago. It looks like the white dots are out competing the green/brown algae. Those rocks were white when I got them and were turning brown initially. What are they? Bacteria? Coralline? Just curious...

    So, I’m coming up on a year in June for my first tank and there have been so many ups and downs. The one down I just can’t seem to shake? Algae. I’ve improved filtration, flow, removed stock, reduced feeding and light exposure (time and intensity). I just can NOT shake the algae. A couple...

    Freshwater dillema

My fathers freshwater tank has been having some weird issues, no matter how hard we try to increase the ph whenever we test it, its back below 6 (way too low), some fish have died from cloudy eyes and...
