Cyanobacteria

I have had some cyano and i cant get rid of it but now it is turning brown

 

[fishmaster818]

How did i get the cyano

 

[mrcoffee2]

Part of the cycle? Low flow? Lots of nutrients?

 

[Reefing Madness]

Happens. Just keep waving the stuff off, net it out, it will go away.

How old is the tank?

How do you export nutrients?

Its about 2 1/2 months and im exporting with filter sock chemi pure elite and a skimmer. My phosban reactor with be here friday

I would kill the lights and stop all feedings until it dies off.
then readjust both so good things thrive and the cyano stays away.

Will my corals be fine

 

[beaslbob]

Will my corals be fine

yes.
the cyano will die off much faster and return nutrients in the correct ratio so the corals, coralline algae, and macros thrive.
then by adjusting you can keep the bad stuff away for good.

Okay my Phosban reactor will be here friday that will help right

It's supposed to.
But then in never used one.
I just used macro algae to consume the nutrients then coralline and corals left behind.

Yes, reducing nutrients is a good plan.

How much gfo should i start with that way i dont harm my sps

How much gfo should i start with that way i dont harm my sps

Or lps

I would go to bulk reef supply's website and use their reef calculator to determine how much GFO to use for your tank, then I'd start with half that amount and slowly add more over a couple of weeks, assessing your corals response. In my experience adding too much at once can stress corals, for me it has been mostly evident with my LPS especially acans. Same procedure when replacing spent GFO too.

If they begin to seem stressed should i leave it of for a little while and then cut down on the gfo

You could, but if you start small and gradually add GFO it is unlikely to stress your corals; adding a bunch at once and quickly lowering your phosphate a significant amount is more likely to cause stress so if you slowly add it you should've have any problems (kiss of death I know!)

Brs says to start with 11 tablespoons so im going to do 5.5 -6. That should be a good start right

 

[WindeyD]

I would think so, we want our phosphates down but don't ever want any dramatic changes in any parameter quickly; them corals just don't dig that!
