    (Good link!! Just for anyone following after this.... #chrysophytes are not a fungus, but an algae. You can click that #tag to find other posts that have been similarly tagged in the past, BTW.)

    Either run a R2R search for the term or hit this tag: #chrysophytes

    (or both!)

    Can you post a full tank shot that also shows the scene in this pic? I'm having a hard time seeing this as diatoms (even if it is). LOL

    Color would suggest #chrysophytes (which are diatom-like in some ways), but the photo still doesn't have enough detail to say for sure.

    Diatoms should also not look that color in the photo real?

    If you can, I'd like to also see results of a "shake test" for confirmation. (lots of details for testing on the dino sticky thread...even for cyano too)

    Put a sample in a vial, shake it up to homogenize it....leave it alone (ideally under a light) and see if it regroups in a mass or if it stays shaken up. Dino's are the only common thing that will regroup. Cyano or diatoms will not.

    I suspect that might be #chrysophytes. Check out some of the posts under that tag and see what you think.

    Is the tank pretty new and do you know what led up to the chrysophytes blooming like that?

    You missed that metro doesn't work.

    Try the search of this thread I put at the end of this line and look at more than 500 posts worth of metro attempts, not one of which ended in a dino-free, side-effect free tank at the end: metro

    IMO, make your current metro dose your last and keep reading! :)

    To make the current strategy even worse...

    Your bloom looks more like chrysophytes than dino's to me.

    But maybe another pic might look different. BTW, you can get a $12 toy microscope (what I have!) and get some great cell phone pics with it if you don't mind holding off further "treatment" until you get a more positive ID.

    In the mean time, I'd suggest starting to search on #chrysophytes. @taricha , @reeferfoxx what's your take? Dino's, or...?

    Also even though your stuff doesn't look like dino's IMO there's a good chance the treatment situation will be the same or similar.

    If you have a thread for your tank already, link it in that Dino thread or PM me if you want. (Make a thread, if you don't have one! :))

    If things overall seem to be improving, then cyano IMO means you could be out of the woods. Keep the nutrients at reasonable, non-zero levels.....if you feel like you need to keep after mechanical removal to save corals then do what you need to. I had to use my judgement to know when, but after I felt I was out of the woods I had luck ceasing KNO3 dosing and just feeding much more regularly than I ever had.

    I would think of this cyano like your tank is going through another cycle just like at the beginning....only this time it's processing a much larger nutrient load. So give this the same kind of timeframe for the tank to "get past it" least 4+ weeks IMO. Just a case of the uglies now! :)

    Are you starting your tank with activated carbon, bio-pellets/vodka/vinegar/similar and GFO by any chance?

    If that's dino's, there has to be something about your process that's provoking this situation for it to be such a consistent outcome on different tanks, IMO.

    Click this tag for some good info: #chrysophytes

    But, generally, it seems like they respond similarly to other harmful algae blooms to a correction of the environment and nutrients. So fix any contributing factors you can fix, including dosing liquid nutrients in the short term, if necessary. And otherwise stabilize the presence of dissolved nutrients until the tank turns around.

    It's still probably nutrient driven...but regardless, post pics of what you get under the scope! :)

    Also, Brandon's quote up there is on the old side now – we're amassing new information on these topics daily, so it's not really fair quoting him from then. :)

    Chrysophytes are most certianly nutrient driven just like every other critter in the microbial food web, they could be a normal background component of most healthy reefs.

    And mine seemed happy "eating" my Hydnophora during the peak of my bloom. I didn't let them take my tank down, but it seemed to be heading that way. That coral went from the size of a dinner plate to almost nothing. Even after this much recovery time, the largest pieces of regrowth are only about the size of a quarter.

    If you haven't already read the Dino thread* and/or the Nitrate dosing thread, now would be a good time for it! Likewise for this post on my blog: A Nitrate Dosing Calculator For Better Tank Health (And Better Coral Color!) Maybe check out any posts that got tagged with #chrysophytes

    Your tank needs a steady nitrogen source and a stable phosphorus supply. Tanks like yours and mine that get ignored probably have not had a bulletproof record on either side of that equation.

    I hope this helps! You're welcome to PM me or post here with more questions! :)

    *Just go to that thread for the background info and photo ID's that so many folks have posted. None of the chemical-based "possible cures" the thread drags you through actually work. In the end you've got to restore a normal nutrient balance.

    Sounds like it's about gone then, eh? Love it!!! :) Great pics and movies too.

    If you can post them, I was curious about the details of any nitrate dosing you tried. (Dose rate, observations you made along the way....anything/everything.)

    KNO3 worked on mine and from what I've been able to read, there's no reason to expect that it would work less well on other chrysophytes.

    (Look for my posts and pics in my Member's Tanks thread, the Potassium Nitrate thread, the Dino thread, as well as one of the Diatom threads I think...and my posts tagged #chrysophytes. was an adventure.

    But I'm now happily tending a crop of plain-looking cyano and a little bit of green hair algae while some of the coraline algae grows back. The Hydnophora has almost doubled in size (from almost nothing left). In fact all my corals have been growing like crazy since. :) NO MORE CHRYSOPHYTES.

    If those colors are accurate on my end, that almost looks like pictures of #chrysophytes that I have seen.

    Not completely dissimilar from what I had going on in my tank either.
