Here is some reading I was able to dig up.

Also if you do a search on "dinoflagellates" or "dinos" you should get some reading, several folks on Canreef have been through this. I've suffered dinos blooms twice -- the first time I was able to knock it under control by starving the system of light for as long as I could stand (my goal was to make it a week, but I got impatient). The second time, starving the system of light didn't really work, but then I moved and the tank was so badly disturbed that the dinos just kind of went away on their own.

I really, really hope this is not what you have.

Now I think if I left it alone and didn't do the water changes it would turn to cyano but it is brown not red but acts the same way with the air bubbles when photosynthisising (sp). Maybe it is cyano trying to get hold but not able to? Just before I do a water change I blast the areas with a small power head to wash off the outer layers. It seems to help a bit.

That sounds more like cyano then. There are a lot of different colours cyano can be, red, brown, green, black (and, presumably, "cyan" given the name although I haven't seen that particular flavour).

A dinoflagellate bloom is rarely, if ever, contained to a few sporatic spots .. they can double in population in a matter of hours (if not minutes) so you can well imagine how fast a tank can be completely overwhelmed. Then they completely disappear at lights-off only to start again the next day at lights-on. Cyano, on the other hand, will also ebb and flow with the photoperiod but seems to be a lot slower.

Cyano feeds on nitrates (maybe to an extent PO4 as well). Do you grow out any chaetomorpha anywhere? Chaeto can be useful tool for sucking up some of that NO3/PO4.. (If you want some let me know I can get you a handful of it .. that's all you'd need. I grow mine in an aquaclear lit by 2x9w PC's and the stuff doubles in size about every two weeks.)

Unfortunately I don't have a refugium. But that might be a great idea for my frag/sea horse tank. I will look into that.

Snappy! Im new to SW...Really new. I noticed that you had mentioned in the first post that you said "at the reef meet on the 14th". I was wondering about that. I live in Calgary and i didn't know there was any such form of meeting about SW. I am still in the process of learing all i can about SW Tanks and i think it would really help me out by being able to talk with people one on one and in the same area as well. Anyway to make it short, i was wondering if you could tell me about that. Where it is, what i need to do, etc etc. i would really appreciate it.

We had a reef meet on Jan 14. Sorry you missed it. We get together about twice a year for frag swapping etc. You can look at the Frag meet at Snappy's threads to get an idea.

If you are dosing iodine, make sure to keep a close eye on it. At higher levels, it's toxic. See Jim Barry's thread in the Buy/Sell/Trade forum....

My level is low. But thanks for the heads up.
