    EMERGENCY Corals bleached overnight

    Excuse the long post but I don’t understand what happened, I’ve been reefing for almost 2 years now. I research for hours daily to better my chances in this hobby. I have a waterbox frag 165.6 that’s been up for about 6 months now, I let it cycle for over a month before adding coral. A week ago...

    Beating dinos

    What do you guys think of this idea to beat Dinos? I have 2 tanks, both waterbox frags. My 105.4 is going on one and a half years old doing extremely well and mature. My newer Waterbox Frag 165.6 is about 5 months old and now it’s getting a Dino outbreak and my nutrients bottomed out. Can I do a...

    Dino’s help

    Hey fellas i have a tank with no live stock in it that had Dino’s. I plan to restart the setup with live sand and live rock. I wanted to clean the whole system before adding new rock and sand. My plan is to drain the tank fill it with freshwater and then run vinegar through the whole system for...

    Battle with Ostreopsis Dinos.....

    Stringy Algae, Dino’s, or cyano(no bubbles)???

    Does anyone have an idea what this could be? I have had them pop up on the past and I thought it was Dino’s, but it disappeared for a while and now has made its way back, but now more than ever. Should I dose vibrant? Thank you!

    When you basically have a refugium in the display tank....

    45 AIO is currently beyond overrun with GHA and dinos. Any and all help would be appreciated, because this is about to drive me out of the hobby entirely. I haven't bothered testing nitrate and phosphate because they're likely zero'd out given the sheer amount of algae in the DT. FWIW, is an...

    Dino fight...

    My son just upgraded his 4 year old 27gallon tank to a 80 gallon, as of today we are at the 5 week mark. We cycled the new tank, seeded with the filters from his old tank. It took about 3-4 weeks for ammonia, then nitrates to drop close to 0. We added a bottle of copepods, BIO-spira, a damsel...

    How long do Dinos live?

    Hi, I have been battling dinos in my 95g tank as both my phosphate and nitrate kept bottoming out. I finally raised my nitrates and phosphates and notice that they are starting to die. How long should I keep my phos and nitrates elevated so they completely die? if anyone can help thanks!

    The last resort: Dino X

    I’ve been battling Dinos for about 9 months in two reef tanks: 13.5 gallon LPS 2 years old and 40 gallon mixed 1 year old. In the 13.5 just prior to the outbreak I had used Vibrant which I believe crashed my nutrient levels after rocking my barely established bio filter and eliminating the small...

    Dinoflagellates ID (Microscope photo)

    Which strain is this? 40x magnification. I looked at images of Ostreopsis and Prorocentrum on Google but they look similar to me. Thanks

    Dinos over 1 year

    I've had dinos so long I feel my self giving up a little, been so long can't remember 1 year maybe more? I've read many things before. I maintain nitrate 4 ppm , phosphate 0.03ppm. So I dont' understand why it remains. Here's a pic and my aquarium logs...

    Dinoflagellate relapse

    Some of you may know me, and unfortunately I am a recurring theme on these threads. School started for me two days ago, and since then I’ve had to wake up at 5:45. My lights are usually set to about 8:30 to 9:00, but they came on at 6:30. When I got home from school there were more...

    GHA suffocating corals

    Hello, I am currently battling prorocentrum dinos and am making solid progress. I have a forest of GHA now, but it is now becoming problematic. It is housing stray dinos in it, while also suffocating my Xenia. Even though it is a competitor for the dinos, it is also a major nuisance. I want to...

    Stringy algae growing out of control and hurting corals! Please help.

    Hello, so I have been into the reefing hobby for about a year and a half now and about 4 months ago I purchased this 30 gallon tank and cycled it, and placed a few fish and corals in. I am at about the 3-4 month mark and all of the sudden this strongly algae began to grow very quickly and in a...

    Diatoms, Dinos, Cyano, and Hair algae?

    Hello to anyone who's here (and thank you for reading)! I think I've encountered my first issue with my reef tank, which is whether I've got dinos, diatoms, cyano, and hair algae - or maybe all four of them at the same time. I don't have a microscope on hand so I'm aware that the best ID I can...

    Second Opinions Never Hurt - Dinos?

    Hi, all! First time posting but here’s another algae ID post. I don’t believe they’re diatoms. They sorta look like dinos but don’t have the characteristic trapped air bubbles. It’s brown, it covers the rocks, tank walls, and only the sand that is in the light. What do you guys think? Tank has...

    Diatoms reforming?

    Not sure if I had dinos at first which I thought were diatoms but if these are diatoms then they are reforming. Does adding more dry rock make diatoms reform? Also it's really only taking off on more of the older rock. Tank is about 1 month and 1 week old.

    Dinoflagellates - do you want them?

    I was thinking about something a little different here, we surelly do not have a simple solution that works for all dinos, unfortunatelly, but for a long time we started to understand what are great conditions that predict dino problems in the future. So this list is kind of a joke (many items...

    Is it toxic dinos?

    Hi, A soft algae-like something has appeared in my coral tank since yesterday.:eek: (mov. 1) I'm afraid that it might be dinos. :confused: I took the piece of it and poured oxydol on it, but its color did not change. (mov. 2) I've heard If it's dinos, it turns purple. Is it unlikely that...

    I’m pretty sure these are dinos, just want to double check.

    If these are dinos in my pics, what should I do to get rid of them? I was thinking dosing nitrate and phosphate but I don’t want to end up with other algae problems or over do it. Any tips? The bubbles do go away at night when my lights are off and they do come back when lights are on. I don’t...

    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...

    I finally beat dinos!

    So my tank has had dinos for a few months, going from good to bad good to bad to worse, with recently being REALLLY bad. Here is a pic from a month or two ago. And here is what it looks like now. To be honest, im really not sure what I did. I manually removed it now and then. the biggest...
