Algea growing on coral!

[salgas]

Hi everyone.
Hope you can help me on this one.
I have algea growing on my corals and don't know what to do....
I already lost a gorgonia and a turbinaria on account of algea growing on them.
Tryed to scrub them but no use algea keeps growing till it finally kills the coral.
Still trying to save my Duncan but the algea Wont stop growing, only one head left... :-(
Help please!
Thanks

I think the issue your having is with excess nutrients, to control the algae and promote the longevity of your coral you need to get the nitrates and phosphates as low as possible. So the algae wont grow at all... I recommend a refugium with cheatomorpha for nutrient export, or I also run GFO in a reactor to absorb phosphates. Also cut back on feeding if you havent already done that. Depending on the algae some extra CUC can keep your coral algae free, ceriths and nerites or however you spell them are good choices. You'll get mixed opinions on this but turn all the lights off over the tank for a few days to kill the algae (more of a temporary fix) also to really help we need to know more about the tank. Parameters, lighting, age, skimmer, sump, volume , and well a ton of stuff actually but my suggestions are at least a place to start.

Let's begin then.
120lt aquarium, cube, rear sump.
Radion leds
Vortech mp10
Bubble magus nac qq
Rowa fos and carbon in "socks"
1.5lt siporax
No3 =5
Po4 = 0
Been battling algea for a while now, there's less and less as time passes, but the ones growing on corals is the problem.
I think they will disappear if I continue like this but till then IM afraid I'll lose more corals....

Hmm you could siphon all of it off the coral during a waterchange, or use a tooth brush and gently scrub it off. What does the algea look like? Increasing flow would probably help too.

I do that every time I do a water change but in the tine between out grows back...
Can't scrub any more then I do without hurting the.coral..
That's what happened with the turbinaria, it began to lose tissue and dyed...
It's a mix of gha and.ciano...
The flow is as high as it can be.
If I turn it up more I'm afraid my Duncan and Euphylia will blow away! :-(
I syphon as much as I can from sand and rock and I notice that it grows less and less every week and my turbos are.doing a good job but still...
Is there any dip I could.give the corals that would help?

Thanks a lot for the input! ;-)

Well I know dipping corals in like lugols or however you spell it is really good for them, that or coral rx but Ive never dipped corals so I cant help you there. I had a cyano outbreak that killed my pink pavona so I feel you pain. My phosphates are only .02 and I still have cyano that I cant seem to kill haha its frustrating, but dipping the corals that are already stressed may backfire on you. Have you reduced your photoperiod at all? That could really slow the algae down.

No problem I know its annoying when everything seems perfect but your tank is still have problems.

 

[jcarey]

I agree on reducing your photoperiod. Do what you can to starve the algae out... That certainly stinks to lose coral like that.

 

[salgas]

I had ten hours photoperiod, reduced it to 8...
Gonna try a dip in rx to see if it helps, can't hurt to try.
By the way, just received an email.from my lfs about a new product by korallen that kills cyano!
2 drops for 100lt per day is supposed to do the trick in a week!
Has any of you guys heard of it?

Algae wont grow on a healthy coral, when the tissue recedes the algae takes over the exposed skeleton. You cut try cutting the algae covered parts of or hydrogen peroxide drip kills algae pretty well, 10 parts tank water to 1 part Hydrogen peroxide for a min or two depending what type of coral. Either way you should look at what's killing the coral other then the algae.

Coral rx dip then H2O2 dip? Rx for parasites and stuff the H2O2 for algae?
