Cyano with no nutrients?
 

In the last week I have had a slight cyano issue.

It started on the bottom which is not sand but crush. And only enough to cover glass. I vacuum it regularly. I don't have any noticeable phôsphates and nitrates were 0-5 ppm.

I blow it off the rocks daily and it's not even really there just slight amount of red tissue and the air pockets. I use rowaphos and prodibio. I feed my tank very little for the most part spot feeding my two fish and 2 shrimp. I run a mce 600 skimmer which does its job fantastically. Also run filter pad @100 micron changed daily

Can anyone explain why this would be without any noticeable nutrients.

i have an old halide that causes the stuff

Maybe low flow in that area ?

Light is a radion at 80%. 14000k and 18000k in evening

Tank has mp10 almost full bore on reef crest

I had this issue for couple month, i used blue vet redslime control and they all gone next morning!

I am prepared to use the meds to be rid of it but there must be a reason why this is happening

I blow off rocks daily to remove it but also to remove deitrus. So I can't see it being leech from rock either

Thats bacteria

Yes it is lol

I was reading on chris88 feature about cyano being a byproduct of carbon dosing. So I wonder if adding different benificial bacterial strain would help this

Yeah, I've also dealt with the "where's it getting its food from??!?!?!?!" cyano. Don't bother fighting it with "honest" methods. Just pick up an antibiotic and call it a day.

Yeah I have cemiclean on hand.

I was just lookin for a reason why but I guess sometimes it is what it is

I had a bit of a cyano problem and a lot of a caulerpa problem.
My tests indicated zero on everything, but I doubted them and bought new kits just to find zero across the board.
Ended up swapping my old t5's out for LED and the problems cleared up quickly.

Since you're already running a Radion my circumstances don't really apply to you and I'm just consuming bandwidth. But maybe too much sunlight or red from the Radion?

Yeah I thought about the light as it didn't happen till I got to 80%. Ill wipe it off the board and see what happens

That would be interesting to see your results. So far I only have my red and green channel up to 30% as it is. I wonder if I'll see a recurring problem when I bump my intensities up more.

Since I started using MB7 more than a year ago, have never had a problem again with cyano. And my P04 and N03 is nowhere near zero. And I use Radions.

Sorry but what is mb7

Nvm. I found it. And def look into it

Microbacter 7 from Brightwell Aquatics. Adds beneficial bacteria which out competes cyano. A must use with bio pellets.

Many LFS's carry it.

Thank you

The label on mb7 says it reduces organic carbon. Since prodibio is a form of carbon dosing will it affect the prodibio performance.

Sorry for the inexperience lol

Don't know about prodibio, but it is recommended to be used with bio pellets, which is carbon dosing. It also prevents a lot of the unsightly mulm build-up that can clog reactors and filters.
