Cyano problem..

Tank: 65gal Red Sea Reefer
Setup 5 days ago
55lb of live rock

I know the tank is extremely new, but I've had some extremely fast cyano growth in 5 days... What is the best way to stop it before it gets too bad?

Take out rocks with it on them and clean real good. Do a partial water change and possibly create more current in the tank. You must have some dead spots.
 
I might wait on cleaning the rocks, or don't do it at all actually, and wait on water change too. The water is five days old... And.. You may lengthen the cycle if you are getting an ammonia spike. I would do nothing and let the tank run in. Monitor the ammonia lvls and nitrate for the next couple of weeks. You are going to see a lot of changes in the next few weeks. Best thing to do is research and be patient. I'm assuming you used rodi or comparable water....?
 
I used premixed salt/RO water that was mixed at my LFS (75gal of it at 1.025)
I'm not showing any ammonia as of yet, but I've been dosing the tank daily with bacteria as they suggested.

+1 I would not pull the rock just yet.
Three days of lights out will knock it back and should not impede your cycle. Increasing in tank flow is a good thought too.
Cyano is really just a part of cycling a tank so be patient and good luck!
 
Ok cool. It does have quite a bit of circulation. I have a power head on each side and the return pump in the center. One head blows behind the rock while the other blows across the front. The return pump blows from back to front in the center
 
Your rockwork looks like it has a lot of areas that are in the shade. You might have difficulty finding corals to put in the places that aren't getting much light. The reason I say that is because when I created my aquascape I did the same thing. Now that I have corals in the tank I have empty spaces on the rocks that I'd like to fill up but I'm having difficulty because there isn't enough light there.
 
5 days in? Cyano?? Completely normal. You're going to go through a lot of different phases over the next few months. This happens to be one of them! Keep up with water changes and maintaining good water chemistry and your tank will stabilize itself.
 
mechanically removing every bit if it is the best solution.
suck it out during water changes, blast it off with a power head, scrub it with a toothbrush.

get a 1 micron filter sock and place it in your sump while your return pump is on,
syphon as much as you can get, then use a power head to blast off what you missed then do a water change and repeat until its gone.

high flow helps to prevent it from latching onto your rock but high flow alone is not the answer.

maintain low nitrates and phosphates and you should be good!
 
Nothing for a while... I seem to be really successful at killing stuff, so I'll give the tank a few months.
But I'd like a really nice hammer for sure
 
Looks good. Unfortunately leds have a tendency to give us all those shadows to deal with. Hammers look cool. I'd like to pick one up myself.
 
Question:
Would it be beneficial to throw my used filter pads from my other cycled tank into the sump of this one to add bacteria..?
 
You could add some pure ammonia to get it to spike and watch how fast it goes down. I cycled a tank in two weeks using dead rock. I didn't believe it cycled that fast so I added ammonia to get it up to 2ppm. Then 24 hours later ammonia and nitrite would be 0. After doing that a few times I added my cuc.
 
Interesting. I've been dosing bacteria, but from I understand, you still need to have an ammonia spike.

And I'm not entirely sure what this means, but when I turn the protein skimmer on it just overflows with small bubbles. When I place the same skimmer in the other tank, it pulls all kinds of nasty slime out....
 
If your rocks are already cured and you're adding bacteria could it be that the tank is already cycled? It's my understanding that you need to put a source of ammonia in the water to get the ammonia to spike followed by a nitrite spike. I'm not sure what happens by just adding bacteria.
 
Well.. The rock is cycled. I took everything out of my other tank with the addition of some dry rock.
I'll grab some pure ammonia tomorrow and see what happens
