I basically already know my tank is in shambles. I posted recently about hair algae, i think i got that under control. The phosphates and nitrates are working there way down. Now it seems like bubbles. They come back daily, so i thought they were air bubbles, but couldnt fiqure out where they were coming from. Now i am starting to wonder if it is algae. They blow right away, easily with a powerhead. I can put my finger on them without bursting, but i have had those bubble algae things before and they were attached better to the rocks and they took a little squeezing to pop. What is it algae or bubb;es. and either way how can i get rid of them? I also have been recently tackling the red slime algae, like i said, shambles. Any advice would be apprecitaed, in my 10 years of reefing, i have never had suych a poor span of events.

Those are air bubbles, produced by the thick mat of cyano you have all over your rocks.


I assume your tank is fairly new, and this stage is one most of us have been through.

The trick here is patience. Keep doing water changes, and try to siphon out some of that mess every time. Keep the skimmer running and do not despair.

Now a few questions:

What is the flow like in the tank?
Do you have any livestock?

the tank was setup for years. Lost everything in Katrina. Restarted with everything new, cept for rock, which was left on in sun. Take has been setup for about 6 months with no rpoblems. Suddenly this algae after a hair algae attack started.

I do have a yellow eye tang and a clown, no corals.

I have my return water flow and 3 power heads in a ninty, same thing I have had for years.

My questions, is that my only attack is water changes?

Can i siphon the water into the sump with the net on the bottom of the hose. I would like to really attack it, but if I did it into buckets i would lose all of my water?

Any suggestions appreciated.

Yes, Do you do water changes at all? That is the best way to do it and it will help remove the excess nutrients the algae is feeding off of.

Also,

Did you recure the LR after rebuilding the tank? I bet there is allot of die off on those rocks from the Katrina disaster.

You can put a filter sock on your drain and storm the crap out of your tank. Wait a couple of hours and storm it again. After another couple of hours, do a water change and syphon any of the loose cyano you can see. Then leave the sock for another couple of hours and finally take it out and clean it. It'll work like a charm. Repeat in a week if necessary. :)

Like Rob said, your rocks are probably dead. How long did you leave them out of water? Do you have any additional live rock in there? You might want to add some in efforts to seed your dead rock.

Lighting and lack of flow also has an impact on cyano growth.

Yes i have always done water changes between 2 weeks and a month.
The rocks setup in my tank with saltwater for about 6 months after they were dried out. I never really went through a cycle though.

I believe it most be coming from the rock, it was just weird everyhting was fine for about 6 months with fish in it, now this. I did leave them out of the water for about a week. I do not have any additional live rock in there, i was fully stocked before the storm.

The lighting wa sall replaced, i thought that may have been a problem. Water flow is powerful, shouldbnt be the problem.

My problem with siphoning was I would siphon for hours and lose all my water. I usually do 10 gallons at a time, not tankfuls, that why I was asking about the sock, and HTH answered that..thanks

gotcha on the amount of water changes.

I would try a fine mesh sock and siphon the water into the sock and back to your sump. This way the water stays in the tank but you are catching most of the cyano. on the areas that are covered with the cyano trying aiming the a powerhead at that area for a while.
