WHAT IS THIS REEF CENTRAL!?

Marko, try dosing vodka, ever since I started with vodka its has helped control the excess nutrients in my tank. I only do a water change when I clean out my sump and thats only once every 2-3 months though I do add 5g of ro a week due to evaporation but everything in my tank is doing great. I also overfeed my tank at least twice a day but my tests always come out zeros.

Thanks for the suggestion,I've actually started dosing microbacter7 to build up the bacteria, I think another week of than and then vodka

I started microbacter7 a few weeks into my battle, followed the ULN instructions, I thought that the daily 10% WC was stripping the bacteria from my system, after a week or so I started the biofuel as well, although it didn't make a dent in the cyano I am still dosing it as a preventative measure but at the stabalized dose, I've been cyano free for a month now ( I feel like a recovering addict ), be careful with the vodka as I understand it's like biofuel on steroids and can strip all nutrient from your system and cause a bacteria bloom.

I think you should be able to breathe a sigh of relief today, some fresh carbon and a few 20% wc should get your skimmer back to normal in a few days.

thanks for your help man. i've got a 55 gallon tank of freshly made saltwater ready to go in tonight when i get home from work :)

Your welcome and good luck. RID THE CYANO!:biggrin:

Give the MB7 time to work before adding vodka or other carbon sources. I dosed MB7 heavily first couple weeks, then only about once a week there after. The beneficial bacteria needs to be well established, before gradually adding carbon, or you will have even more cyano. But once the MB7 and beneficial bacteria are established, the carbon (I use bio pellets) will do the job. I have not seen cyana since.

Hey Marko, I havent read the entire thread but most of it, Have you tried a black out period at all? I have heard that it helps as well, or atleast shortening you light cycle. I could be wrong though. Hope the battle goes well. Cyano is an ugly "b"

I tried the blackout, 4 days no light except 1/2 hour a day ambient light to feed the fish, cyano was gone but quickly returned a couple days later and seemed to spread even faster.
Cyano is probably the most resilient, opportunistic thing on this planet and normally we can keep it in check but sometimes something happens and you get a plague.
I am totally against chemical treatments but I have to thank chemiclean, I was getting ready to quit.
