So what are we thinking they do to the coralline? Alk and calcium good, coralline no good. Can Dino's give false reading on our tests or are they directly stopping the growth and turning it white?

if the dinos are covering the coraline algae then it could be a light issue, even if a small layer it could be blocking or filtering out some light.

I thought it was a common thing for people to notice a change in coralline when Dino's popped up

My coraline receded quite a bit while I was battling and has come back quite nicely now in only a few weeks, I noticed a brown film on the rocks, barely noticeable, and it wouldn't blow off with the baster that could have blocked some light. Could be a toxin thing as well.

I'm sure Salifert is not consistent as the kit ages.
Below is from this thread.. http://www.reefcentral.com/forums/sh....php?t=2273650 14 months have passed and today I got 3 new Salifert test kits. The old calcum test kit gave a reading at 340 The new calcum test kit gave a reading at 375 The old alkalinity test kit gave a reading at 5,7 The new alkalinity test kit gave a reading at 5,7 The old magnesium test kit gave a reading at 1185 The new magnesium test kit gave a reading at 1350 There is a tendency for the calcium kit to drop as it gets older. Three comparisons have revealed 40, 20 and 35 lower numbers in the older kits. The kit that showed higher value the year before will become the lower next year. Alkalinity stayed at 5,7. Magnesium I'd say is more correct for the old kit compared to my Ca and Alk levels. --- This issue with my low calcium readings and the massive amounts of added calcium without any coral growth is a side effect from the dinoflagellates combined with the Saliferts kit inconsistency over time. For a very long time I had white coraline coverage on all well lit areas and purple everywhere else. For the last few months everything has turned purple like it's meant to be. I've had a derasa clam for more than a year. It seems to be healthy, but I can't tell if it has grown at all. |

The coral would turn light gray and could stay that way for months. Most reefers would think it dead and throw it away. When the coral finally dies it would turn bright white. |

In my tank I noticed that the brown film that was growing on my glass was also on the rocks and coraline, and when I swabbed it and put it under the scope they were the same, about 90% diatoms and 10% dinos and I couldn't blow it off but I could wipe it off.
This was after I removed the sand bed, before it was probably mostly on the sand. |

is dinoflagellates or cyno????
is this dinos or something else? to be clear…i don't see long strings or air bubbles and this is mostly on the sand. although i have seen some spots of the ruby red stuff on a few rocks. i can blow it off with the power head. also, if i use a power head on the stuff on the sand, it will roll up like its one piece…almost like a mat….

You got both.
Purple Cyanobacteria and brown dinoflagellates. |

Doing a simple Google search using "cyanobacteria in a reef tank" reveals that the most common cause for cyanobacteria in reef tanks is dinos.
A lot of diatom pictures seem to be dinos as well. Does anyone have a solid way to eyeball diatom mats from dino mats on the sandbed. A microscope would be the best way and there could be a mix at any ratio of the two. If fish are eating the stuff and staying alive it's sure to be diatoms. Not to forget that diatoms stay for the night. Last edited by DNA; 07/20/2015 at 02:49 AM. |

And then obviously the bubbles can mean either cyano or dinos. I think that comparison is a little harder to make because it can also be both dino with cyano. However, my cyano mats have been a lot thicker than when I had a bad dino bloom. |

I was more thinking of a fast id from a decent picture.
The reefing community is oblivious to what dinos can do to reef tanks. Reefers keep struggling and don't get it why their corals don't thrive. Cyano and diatom problems are much more common than dino problems, but are they just that? It does not take a big dino bloom to do havoc, a few patches here and there can make the SPS experience miserable. We are not doing enough about it. It will take more than a hobbyist from Iceland to get the blue whale in the lagoon out of there. |

When I was fighting dinos two years ago in our propagation systems, the Ca and Alk were wonky. Couldn't add enough Ca to budge it. We were dosing up to 10 gal a day of kalkwasser into a 400 gal system and couldn't budge Ca from 320 or so. We weren't sure if something was consuming it at an enormous rate or something was affecting the test results. Test kits were typically API with Salifert tests run and a professional lab analysis to confirm. There was no precipitation.

Does anyone know if some dinos kill Shrimp or is it only snails?

Didn't mean that. Lost fish and snails, but my harlequin survived. Also my maroon clowns have survived everything.

Perhaps someone smart could make a simplified key? Does it kill your snails, go away at night, like light/flow etc etc Ivy Dinos Club never going to be as popular as Diners |

tampasnooker,
interesting comment you made about the calcium. i have nearly the same issue....i can move my alk around with simple two part solution (soda ash) but calc will not move if i dose the same amount of calk...i have no SPS and only two LPS...good coraline algae growth though....wonder if there is a connection.?? |
