View Full Version : URGENT: dinoflagellates????

09/03/2011, 06:45 PM
Ok guys so my tank is over a month old and the last couple weeks have just been horrible. There is some weird algae growing that I can't really peg or contain. I first thought it was bryopsis, then assumed maybe its just hair algae, and then today I saw a scary snot looking bubble and thought DINO? :(

Please help me figure this out. Here is the bubble I saw. Note, there was only one. After taking these pictures I stirred up the sand bed to hopefully make the algae go away a little. My snails and hermits dont seem to do much with the sandbed!

Here is the bubble (sorry for the out of focus picture)






On glass:


My tank is a very blue color, so the pictures look like it is more red algae (cyno?) but in person the algae is an ugly green color.

BUMP - someone, help me out please!

For the time you have the tank running that is normal.. The bubble looks like dyno or cyano. This will go away after your tank's water chemistry settles in.

Have you tested anything yet?
What do your parameters look like?
What kind of water are you using?

Thanks so much for the reply. I really hope its not dyno. Apparently dyno is really slimy on rocks. Luckily, I have very little if anything on my rocks. My sand is just a mess. Also, I researched that dyno doesn't "clump" it just oozes over stuff.

I'm hoping its just a bad case of hair algae or cyano. Yes, I have tested my tank. Everything looks great.

Ph: 8.2
Temp: 78
Ammonia: 0
Nitrates: 20 (I need to do a water change)
Nitrites: 0

I do not have a phosphate test kit. I was thinking of using chemi clean. Do you suggest I do?

Better pictures under whites?

I have no clue what that stuff on your glass is though!

Is it on the rocks? I have had Dinos twice so definitely know what they look like, does not look like it to me.. looks like a standard algae to me due to a system spike. The one on the glass is very common as well. Give the system 3-4 weeks and should clear up given you have the right amount of flow and adequate skimmer. Looks like the system is right on track.

Thank you so much for the replies. Glad to hear they aren't dinos. No they really arent on the rock, just predominantly on the sand clumping like in the pictures.

And unfortunately, the pictures are with the whites and actinics on - I went for a blue look but the camera makes it look WAY BLUE! Wonder if that color spectrum has anything to do with the algae.

I'll try and get a pic today of it with just whites. Maybe that'll get a better picture. This algae has been here for 3 weeks now....shouldnt it have been gone already?

More info that I forgot to mention, we currently do not have the sump and skimmer set up. Maybe thats why it is taking forever to go away?

Depends on the maturity of the system/live rock. You must reach a balance were your good bacteria is balancing out the negative bacteria causing the spike. 3 weeks is not that long considering the age of the system. I have also had this clumping algae and went away eventually. If it is still there in a month then something in your system must be adjusted. I think its right on track

Look at this thread.


This should help you. If I had to guess I would say it is the start of Dino. It might clear up though..The algae on the glass is Bryopsis pennata and is very hard to pull off of a rock if gets established.
