    I have recently been battling a huge outbreak of cyanobacteria as well as flatworms. I'm not sure what is the proper approach to these issues. I'm not a huge fan of chemical treatments and I always prefer the more natural approaches to fixing issues. My water parameters are right on where they should be, with regular testing. I run a chiller, so the maximum temp swing on any day is only +/-2.5 degrees. I still have a huge slick of cyano that has been occurring.

    One thought I've had on the cyano is that my lights are old? I run 3-150W 20k HQI and 4-96W Dual Actinic on a 125 gallon. I have had the lights six months, but they were used when I got them. I was told the bulbs were six months old when I got them. So I have ordered new bulbs and they should be in by the end of the week. What other suggestions does anyone have on other steps I can take to battle the cyano?

    The flatworms are mainly present on two pieces of coral but I think the population is growing. I did add some wrasse to my tank just this week to see if they begin to diet on them, but if the masses increase what should I do?

    Chemiclean. I know you said you want to avoid using chemicals, but to put it simply, this one works amazingly well. It does not affect fish, corals, or other invertebrates. I use it from time to time, when the cyano gets to be too much to deal with and have had no ill effects.

    Good luck,

    GFO - Granulated Ferric Oxide. I had a cyano problem a couple of months ago, and after 2 weeks of using GFO, it was gone. I just put some in my mesh bag that I use in my Whisper 40 power filter and change it out every 2-3 weeks.

    This is my experience with cyto - It will happen if you don't use RO water, over feed or don't have enough flow (or well positioned flow)

    This is what I did and it took 2 weeks to eliminate.
    Stopped topping up with tap water (no chlorine )
    Use chemipure elite
    use cheto in my refugium (allow it to mature)
    Sold one of my sun corals
    Daily blew off the cyto from the sand
    wet skimmed
    checked PH daily (cyto will effect ph)
    increased my CUC by 20% (mostly nuss snails)

    It worked 100% for me - I have not had an issue since.

    +1 chemiclean is not a solution in itself, GFO is. Even if you ran chemiclean you'd need to run GFO to remove all the PO4 anyways or else it will just come back....

    I had a Cyanobacteria issue with my 39ga and took the advise of a fellow 3reefer "NO light " for four days and Chazam... ALL Gone. As I'm sure you are aware however address the problem as many here have mentioned Flow,Overfeeding may be culprits that was my problem.

    As far as the flat worms if they are contained to one rock i would nuke the rock done....

    Wow, I've been doing this for years. It is 100% effective. I actually hesitate on recommending it because no one ever tries it. They would much rather spend their money on antibiotics. I have always coupled this with an aggressive filtration of GFO.

    As for the flatworms, I have always had good luck with yellow coris wrasses.

    Flatworm Exit works well to kill flatworms once they are in your tank. But, to help prevent a future infestation of flatworms, I dip all my new corals in an iodine bath like Tropic Marin Pro Coral Cure before introducing them into my tank. Understandably I get a bit paranoid about introducing things like flatworms into my display tanks.

    in terms of the cyano I would have to agree that chemiclean may get rid of it initially but it doesn't always stop it from coming back. Lots think of it like a band-aid but it doesn't help you understand the source of why you had the outbreak.

    I had a little outbreak in my new tank and adding a good CUC stopped it from getting overly bad. I also use RO/DI exclusively and run Chemi Pure Elite in my sump for PO4. Make sure your lights are not really old & make sure there aren't too many dead spots in the tank where it can grow. As others mentioned, overfeeding can raise your NA levels which the cyano can also feed off of. It's feeding of some nutrient in the tank so figuring out what that is, will help you get past it permanently.

    I just wanted to put in my two cents about getting rid of it initially..

    I want to give praise to Micosidol "No red algea" by Columbo. It worked amazing. I dosed it in my sump so my pump could grind it up and spit it into the tank, and let it work for 3 days, and all of my cyano was gone, and my infestation was HORRIBLE. I then ran my carbon/gfo reactor to get rid of the treatment, and haven't had a problem since.

    I do agree with the idea that it needs to be prevented with not overfeeding, ect. I just really wanted to give a plug for Micosidol for how wonderful it worked, incase anyone else needs it. :)
