OK so I have tried everything to remove cyano. Tried flow, changing gfo and phosguard regularly everything to no avail.....My tank only has 2 eels in it right now and a bunch of leather corals and anemones. What do you think will happen if I kill the lights for like 3 days?
 
add big weekly WC's,& cut back on feeding to what your doing now,& it will go away.

Macro algae in a refugium will help too.
 
Well I do 25 gallons a week. I do not feed because the only things in the tank are 2 eels. I lost all my fish to a disease so iam leaving the tank without fish for a few months. So what do you think about leaving the lights off????
 
Ive heard of no lights working for algae,but not on a bacteria,but its worth a try.

Ive read alot here about the Red Slime Remover working,gut i have no personal expierence with it.

FWIW,a good friend of mine has a 210,& does 45g WC's a week.
 
Yeah your friend is doing more than is neccesary. 20% a month seems to be the norm for most.

Perhaps unnecessary,but he has no Cyano?:confused:
 
Something is fueling the cyano. Lights out may work, but the cyano will come back once you return to your normal lighting schedule. I'm not a fan of adding chemicals to my tank aside from kalk, to deal with the cyano. If it were me, I'd go with increased WCs and macroalgae. Its not an overnight fix, but it does work.
 
Good flow is critical to solving the problem. Siphoning it off does help along with reducing nutrients and increasing flow.
 
People.....please do not take offense to this....My point of this thread was to ask opinions on running a tank with no lights for three days. I was more curious about people who tried it. I am not a new person to this hobby so I know about the flow and the nutrients and of course the RO water. So please if you have run your tank with corals in it for 3 days with no lights please let me know the results. Thank You
 
RBU1, not trying to be snide, but I think what others are trying to tell you is that you're barking up the wrong tree. That's all.

Ditto. 3 days without lights is not going to make the cause disappear, work on correcting the cause and the symptom will go away. And no, 3 days without light will not cure your problem only deprive your corals and anemones of light.
 
Well, to answer your question...running your tank without lights wont harm your corals. I've never done it myself, but there have been many threads of people who have and their corals came out of it just fine. As far as will it fix your cyano problem? Probably not, b/c it will most likely come back. So what's the point in doing it to get rid of a problem if the problem will only come back if you don't address the underlying issues that caused it? That's my logic anyway...FWIW

There's even an introduction in this month's Reefkeeping magazine that touches on this method.

I don't know were to begin......First of all I have been in this hobby for several years and have done several things to address the cyano. None of them seem to work. I would really like to see some pictures of your friends tank that does the 45 gallon a week water change.

In my opinion a water change that large causes to much stress on the tank.

A little backround on my tank. It is a 300 gallon system that utilizes 2 closed loops both powered with Reeflo Dart pumps with 2 Ocean Motion 4 ways. For a softie tank that is a decent amount of flow. I recently added a Vortech 40 to the mix adding an additional 3600gph. So again I don't see flow being an issue.

Now as far as filtration I have a sump/refugium with chaeto. I have a large reactor running carbon that gets changed out the first of every month. I also have a large reactor that I run GFO in and also change that out every month sometimes 2 depending on the flow coming from the reactor. I recently changed out the GFO for some Seachem phosguard. I figured I would try using a differently phosphate/silicate removal media and see what happens. So I really can not see the filtration/filter media being an issue.

I change my bulbs beginning of the year. They are 8 - t5's and 3 250 watt halides. I am not running the halides because the corals I have do not need that intense light. I don't see lighting being an issue.

SO what could be causing it I have no idea. I also recently had an outbreak of velvet in the tank so all fish have been removed. So feeding is only target to 2 eels that are still in the tank. So I don't see overfeeding being an issue now. It might have been when I had my fish but they have been out of the tank for about 3 weeks and I see no improvement in the cyano.

Maybe it really is not Cyano but some other type of issue. I am no algae expert but this algae is a reddish brown color and seems to mostly go away at night when the lights are off.

Thats what I really hate about some of the people on this site. I asked a specific question and I get answers that don't help.

There has to be more to this cyano/algae stuff that we are just not aware of yet.

So as far as barking up the wrong tree that is your opinion and you know what they say about opinons.

OK so what will make it go away??????

You can see I have tried everything else.
 
Hmmm. I didnt think cyano came and went with light cycles. Maybe its something else? I have never heard of anyone having problems with corals doing a 3 day light out. It couldnt hurt to try it.
I would do a decent sized water change and suck off as much of the slim as possible prior to the lights out. If you get your temp and sg exactly the same as your tank water, I dont think a sizable water change has any stress impact at all on your livestock...if it does it will be very temperary.
Have you tested you RO with TDS lately?

Yes I have a meter hooked up to my unit to always monitor the water coming in and the water going out. I change all my filters on the RO every 6 month no matter what the level is. I change the membrane also in the beginning of the year.

And Cyano definetly comes and goes with light cycles.
