ID and help.
Can anyone help ID this? It's in a friends tank and he is nearly ready to give up. My first thoughts were dino's but all his snails are still living. The algae seems to be photosynthetic and re-appears within an hour of syphoning out. He has had this problem for about 2 months now and the tank has been set-up about 5-6 months. After about 3 months there was an outbreak of hair algae which died off and seems to be replaced by this. Maybe this was caused by the h.a. dying off??
I've tested his water and all parameters seem reasonable- alk-8.2 ca- 380 (bit low) no3 2-5 ppm ph 8.2 solid. tested and re-tested with 2 calibrated meters. all tested on salifert kits (except ph) p04 was 0.1 2 weeks ago Since testing p04 we've added 1lt of p04 remover and it has been 0 for over a week now. p04 tested with deltec kit. tank is 120 gal eco- system to which we've added a skimmer in the last 2 weeks to try and help problem. very light fish stock and just a few softies and lps plus a clam and some sps frags. I searched and read through countless dino/cyno posts and seems to be the only thing we haven't tried is raising ph. Any help even just ID this stuff would be greatly appreciated. Thanks.

I tried to fix your image tag, but there is no figure at that link.
Try posting it in your gallery here.

That does seem to look like dinos, and if you haven't tried it, I'd try, but there is no easy cure-all.
All I know about dinos is in this article: Problem Dinoflagellates and pH http://reefkeeping.com/issues/2006-11/rhf/index.php

That's what I first though it was.
 Can snails survive certain types of dinos? He has nassarius, ceriths astreas and mex turbos, all doing fine. This only appeared when the hair algae started to die off, do you think that could be the cause or connected in some way?It's a really thin film which is very difficult to syphon, he called today to say it's back with vengeance after spending hours on sunday cleaning. |

Dinos can release toxins, as can other organisms, but I would not draw any conclusions from snails not dying.

I agree, not dino but more than likley diatoms or cyano. Take some out and rub it between your fingers and see if it feels like grits of sand. If so Diatoms.
