lighting vs cyano

is it possibble to create or wosten a cyano prob with lihjting that is out dated? I use t-12 lighting and have recently developed a worsening problem.
I have not replced lighting in about 1-1 1/2 years. Whats the thinking on this?
 
replace it and let us know how it worked.
the idea behind it is that the shift in spectrum and intensity will fuel the bloom, but did you change anything else...?
 
ive noticed in aquriums with bottoms covered with cyano that objects that cast a shade will have no cyano in the shade
 
IMO,cyno can grow in about any lighting,new or old.If your fighting cyno,your phosphates are to high.Changing to new lights,with the increased amount of light,may make it grow faster.I use chemclean when an outbreak occurs.
 
in a tank with lots of liverock and no protein skimmer, hermit crabs and a skimmer helped to almost completly eliminate the problem
 
I have been reading numerous threads on this subject and not to cause anyone offense, I don't think anyone has a clue as to what causes cyano problems. I have been battling it for 3 months now, ever since I put up my tank. My phosphate levels are undetectable (new Merk kit) and so are my nitrates. I skim heavily with a bubbleking skimmer and use carbon changed monthly. My bulbs are new and I change 35 gal a week of water. So tell me, why is my tank covered in cyano?
 
reefkeeper2 you kind of hit the nail on the head, no one knows exactly the cause or cure but we do know this.

good housekeeping skills will limit the bacterias growth potential. i find with carbon some brands are worse then others in feeding cyano. i also note that sometimes tanks go through small algea cycles and it will come and go, depending on severity i will use chemi-clean to combat it.

i have not met a cyano i could not win the battle with. my friend down the street with a FO and poor skills can not beat it for the life in him.
 
I used to have moderate cyano problems until I added a big fuge about a year ago. I've not seen Cyano since and none of my husbandry practices have changed.
 
nazzy_19, raising Alk. to what? Keeping Alk. where? My Alk. stays @ 11.2 dKH. pH @ 8.4.
I am just starting to have cyano problems after my 150gl. has been in operation for 8 months now. I have it in my sump in my refuge (the cyano is out competing my chaeto), and in my tank. It started about 3 weeks ago with very little in my refuge. Now it gets worse everyday.
I don't want to put just anything into my tank. Is ChemiClean the only product that we should consider? I don't want to kill anything on my live rock or sand.
I use RO/DI. The DI cart. is a little over 5 months old, maybe this could be it.
I am going to get a phosphate test kit from LaMotte and test for this.

I agree with nazzy-19,Keep your Alk high.If you have a fuge with plants/alge. I would say dose Kno3,cause the nitrates compaired to the posphates are to low. No3/Po4 - 16/1
Or you can try a Po4 remover.
 
i'll throw my 2 cents in here
i had some patches of cyano that were getting larger by the week just before hurricane wilma last year. i lost electricity for about 12 days. i turned off all my lights during that period.i ran my sump pump, 1 powerhead in the tank and the pump for my skimmer on a generator.
all the cyano (died off)? and hasn't been seen since:lol:
my guess is cyano loves light
:confused: mike:confused:
 
Cyano is normal in new tanks. Live rock requires some curing to minimize this, and even then diatoms appear on the glass and rocks. Astreas help knock down algae - I use 1 per gallon and have no algae.

Brad - Algae loves light and old bulbs even more. Lower your photoperiod now and especially when you change your bulbs
 
Just a thought but since adding a maxi jet 1200 to my 75 gal sump at water level basically ripping the surface of the open sump my cyano problems have gone away.

My hunch is the higher the oxygen level of the tanks water the less problems you will see with cyano.
 
I have battled cyano and won. My solution was running phosban and carbon seperately in small HOB filters commonly used for freshwater (you know the ones) doing daily water changes and scraping/sucking up and cyano I could see with the turkey baster. It took a little while but now I am cyano free.
I believe that phosphates are the key to it's growth, and that phosban was the major ingredient that caused it's demise. Also, having a refugium with a good healthy culture of Chaeto will help with the uptake of nutrients that would otherwise fuel the cyano.

I am going to give it another month. If I still have no sucess, its time for chemi clean.

Not sure of chemi clean, but Maracyn (erythromycin) will clear up the cyno overnight.
Of course, it not the best long term solution.
