Dinoflagellates

How long did you have your lights out for and was there any ambient light hitting your tank during that period? They came back within a week or so the two times that I only kept my lights off for 2 or 3 days and didnt cover my tank to keep the room lights from hitting it. It took a 5 day blackout to rid my old tank of them. I just did 4 days on my new tank and things were still looking good when I left for vacation earlier this week. Im keeping my fingers crossed that I come home tomorrow to a dino free tank.

I really dont think that high nitrate and phosphate levels are necessarily at the root of the problem. In my paticular case I dont think it was the issue and there seems to be others reporting anecdotal evidence along the same lines.

I only did 2 days no lights. That didn't really do much. I think the lack of WC and syphoning them out was the way to go. Went home for lunch today and I'm not really seeing any long strings with bubbles. I'm going to give it another week of No WC and if still no sign of them I'll start with my WC's again.

It happened to me every time my Diamond watchman started excavating in a new area. I think it was the substrate. Thankfully it ran its course and doesn't happen anymore

That can cause a bump in your cycle with a nitrate increase as the end product so that makes sense, especially if it's a smaller system.
 
So I'm going on week 3 with no WC and they're still in there. I did stop dosing peroxide as the bta was mad and so were a few of the lps. I'm not getting the long strings but I am syphoning them out through a sock and dumping the water back in every day or two.

I'm probably going to do a WC today as I'm worried that there is a breaking point where the whole thing will crash. I'll post if there is a bloom again.
 
They are a royal PITA. Are they bothering any of your corals? If not I would wait it out and go ahead and start your water changes again. If the are showing up on your sps I would think hard about doing a longer period with your lights off and cover your tank so no light can get in.

Knock on wood... they havent reappered in my tank since I blacked it out for four days. I stll have some cyano but I can live with it.

The only one is a setosa that had a dead tip prior to this. It looks dumb because it can't grow back over the top. LOL. The little frag looks funny.

I would also trade these dino's for cyno at this point. Easier to manage.
 
Id probably wait it out also. It seems to like sps tips for some reason. I had it on severals pieces and it was always on the tips.

Thats why I syphon every day or so.

Whats funny is my corals have never done better. I have great colors and growth.
 
So they are still there even with the syphoning and all. I decided to take a different route. I changed from seachem phosguard to BRS GFO. Hopefully this helps somewhat. If not with the dino atleast with the HA that has started to pop up. :crushed:
 
Got me. I have shrimp crabs snails starfish urchins nems corals. Never had a problem. But then that's why every tank is different.
