cyanobacteria is killing my zoas

[juanmanuelsanch]

hi all ! For some reason Im having a cyanobacteria bloom, I dont have many corals, but it seems its going after my zoas colony.

Im doing water changes, params are as following.

Ammonia 0
Nitrites 0
Nitrates around 20
Phosphate is not 0, but thats coming from an API kit. Probably its a little higher.

I have chaeto in the sump along with a reactor with phosban in it.

I dont know what else I can do.

Im not overfeeding or anything.

Its a 1 year old tank. I did have some troubles in the last month. Taking extreme measures that wipe out some of the micro fauna.

Any help is appreciated !

You could try siphoning the areas of where the cyanos are and reduce the amount of lighting you provide.

cyano is a bacteria. keep up with water changes, and try microbac7. worked good for me. kindof a good vs bad bacteria thing.

Exactly. Some bash it's use but it works and has minimal if any negative side effects for your tank.

Just siphon it out and top off with saltwater. You may have to do this several times, but each time you are exporting the bacteria and some of there food. So each time it comes back weaker and slower until it doesn't come back at all.

If it keeps coming back, you have bigger issues.

Along with siphoning the Cyanobacteria out you might want to get yourself a soft brush and use this to kind of clean the polyps so to say. It will definitely p!$$ them off and they might not open for a day or so, but removing anything that the siphon may have missed is definitely a good thing.

Just out of curiosity what's keeping the Cyanobacteria from coming back again? The conditions are obviously favorable for it. This kind of just sounds like a quick fix to an underlying problem IMO.

I had a pretty bad outbreak as well, I vacuumed as much as I could using a bucket and an old pillow case to save the water/sand I sucked up and.increased the flow in my tank. Haven't had a problem since..GL

This is so true and i think once the polyps get larger the less often you need to brush them.
(I use an inch wide brush that's tapered after removing the crud with tweezers and or a pick)

Give the area with cyano more water flow if you can.
