Battling Green Cyano

[Andrei P]

Hello ,
i have a problem with Green Cyano in my RS Reefer 350(~100 gallons) . The Cyano is covering the rocks and a few little spots on the sand. The tank is a sps dominant with good coloration and growth on all my corals. The only thing that bother me is the look of this bacteria .
The tank is 1.5 year old , and the parameters are:
* PO4: 0.08 ( Hanna )
* NO3: 5 ppm ( Salifert )
* KH: 8.4 dKH ( Salifert )
* Ca: 420 ppm ( Salifert )
* Mg: 1325 ppm ( Salifert )

I only use RO/DI water with 0 TDS.
From the start of this aquarium i've used Rowaphos to reduce Po4.
I have a refugium with Chaetomorpha.

Some observation:
The flow is covered by two Jebao RW8 that are set up almost at full speed
I tried to battle cyano with bacteria ( Special Blend Microbe Lift ) but nothing happend.
I tried to blow the cyano from the rocks with a turkey baster but came back after a few hours.
I tried to reduce the photoperiod , this method it is working but just a little bit.
I've noticed that the cyano is increasing when i dose Aminoacids ( 1 time / week ) .

What i plan to do:
Start dosing No3Po4-X ; 2 ml - 100 gallons .

The only thing i can think of is that my No3 is not balanced with Po4 ..

What do you think ? It is ok to start dosing No3Po4-X for my problem with cyano ?

NoPox is a carbon source and could make cyano worse.
Carbon dosing fuels good a bad bacteria's.

I would not push down your phos and nitrates any lower.

Have you been dosing anything else like Vibrant? It has a carbon source too.

At the moment I am also battling green cyano. Increasing flow throughout the tank long term definitely seems to keep it at bay. Option two is you start using a product like chemiclean that is designed for cyano. Both can work.

I had various algae issues myself over the last few months. Tried chemiclean, tons of water changes, other algae popped up. Finally did 3 days lights out and tank looks great again, and bought lots of cuc. Good luck

My cyano definitely got worse when I tried nopox.

I’ve been having various algae issues over the last month in my established reef. Used chemiclaen did tons of water changes which turned things into Dinos. Finally did 3 days lights out with a rebuffed cuc and tank looks great. Sometimes natural is best. Good luck

Oops lol

No , i did not use Vibrant .
I have this problem for some time already, ~ 5 months ago i've used some pills called Cyano Stop :) . The Cyano disappeared , but i had a invasion of diatoms for a long time.
After diatoms passed away , cyano came back :rolleyes:. That is the reason i don't want to use chemical products again.

I change water every other week ~ 15 % with Red Sea Salt ( blue bucket)

I dose:
Ca , Mg , Kh daily( AquaForest )
A , B ,C from GroTech (trace element) and M ( aminoacids & vitamins ) 1 time / week .

If i go with the blackout idea i have to cover the aquarium with something to stop the light from the room to penetrate or just to shut off the aquarium lights ?

Thanks for helping me ;)

P.S: I've stopped dosing NoPoX , dosed only 2 ml before reading your thoughts.

In the picture below you can see the cyano that is covering my rocks .

You might want to try an ICP report to see where your trace elements stand, or just stop dosing them, and see if it fades away.

Really not that bad from here, but I understand you want it gone.

Corals look happy... :)

 

[Andrei P]

It is possible to make cyano if my trace element are higher or lower than normal meanwhile all my corals look ok ?
I ask you this because the GroTech dosage is based on the volume of the tank.

 

[AngryMike2016]

Yes. Dosing any element based simply on volume of tank isn't something I would be comfortable with. That doesn't take into account the kind of corals, consumption rates, etc. If I were dosing trace elements, I would base it on ICP testing.

Yeah,
Too many water changes can open the door for dino's to take a hold... :eek:

(lol)
Don't want your display water to be like RO/DI, lab water.

Any updates?
