Thread: Cyano frustration
06-06-2008, 07:53 AM #1
After weekely water changes, constant cyano harvesting, and glass scraping for a month, I STILL can't get rid of this pesky cyano. I am thinking about moving all of my corals to a bucket, and brushing off all of my LR in a bucket of fresh water. Would this harm my rock?Money can't buy happiness, but it sure can pay the rent.

Sorry Drum I am not familiar with Saltwater tanks <shame on me!> But is it not possible to blacken out the tank for 1 week? In freshwater tanks you get black binliners and tape of the entire tank so no light can get in and leave the lights off for a week...this usually kills the cyano fast as they thrive on light. Just a case of vacuuming the dead cyano as soon as the week is over.

I don't think I could do that, becuase I have corals in the tank, and that wouldn't be good for them. I have cut back my lighting by 2 hours a day though.Money can't buy happiness, but it sure can pay the rent.

'Tain't just light that's feeding your cyano; it's something in your water, either high Nitrate (doubtful) or high Phosphate (probable). Gotta eliminate the cause as the 'cure' of turning off the light doesn't mean you won't have a cyano plague again after you turn them on again. And I hate to tell you this buddy if you had EXTENDED your lighting period instead of diminishing it, you'd have an easier time with it. More light = faster growth = eventual diminishing of whatever has been feeding it.
You can speed it up by using one of those iron oxide pelleted products to remove the Phosphate down to NSW levels. Need a bag and a little canister for best removal.
Long as you have the over NSW levels of Phosphate you'll be battling forms of undesirable algae for what will seem like eons.

If you have high phospates causing the Cyano then lengthening the light will cause a complete explosion... faster growth through higher lighting will not diminish cyano at all...it is not an algae that is competing with the other contents of the tank but a bacteria - it multiplies through photosynthesis so the higher the light the more it explodes.
Test you PO4 if that is high lower it....if you cannot dim or put the lights out you will need to manually remove the cyano daily and change water frequently... there are also antibiotics which can be used but as I mentioned before I am not familiar with salt water.
Cyano is a common pest in tanks that are just starting up or have only been running for 2-3 months even when all the parameters are ok.

Have you been using RO water for filling the tank/water changes? If not, chances are your tapwater contains high phospates and thats causing the cyano.

Drum, I can feel your pain. My tank is going through the Cyano stage of the maturation process of the tank. I talked to my LFS a wee or so ago and they told me that I wasn't alone, everyone that had been coming in was having cyano issues. Even my LFS has some cyano growing in their tanks.

I have been using RO water. I found a store that sells it. They go in the back to fill it up, so is it possible that they are pulling my leg, and selling me tap water. RO water shouldn't have Phosphates, should it?Money can't buy happiness, but it sure can pay the rent.

Hmmm, perhaps I should start going to the LFS all the way across town to get water then. Its 15 miles away, but as long as im not getting shafted on my water, then its worth it.Money can't buy happiness, but it sure can pay the rent.
