I have been getting a bright yellow slime on my sand bed and, in places, on my rocks! What is it and how do I get rid of it!

It looks more green in the pictures that it does to the naked eye.

Possibly Cyano. Looks like some red in the corner too

my tank went through a phase with this stuff and everyone claimed it was cyno. also tried to sell me chemi clean. instead i bought a yellow eye kole and it took care of it.

You know Wayne, I have the same thing in my tank. It's only been there a few days. I wonder if its something thats in our water?

Could be, but I use RO water only!

I think im going to treat it as if it is cyano and see what happens.

Decided im going to do a three day complete tank blackout to try and rid of this 'cyano'.
Along with blacking out the tank I am going to put in new carbon, put GFO back on, and skim HARD.

I have heard good things about this so I am hoping its gonna work!

I did the three day blackout and all of it went away just as I was told it would... but.. within 3 days it was all back again.. I'm kind of at a loss because my PO4 is 0.03 and Nitrates are negligible as well. Perhaps the reason for the low numbers is due to the rapid consumption of the P04 and nitrates by the cyano.. but I am unsure..

In a couple weeks I will try again but am going to try and pick as much out as I can first.

How's the flow in your tank? I read your build thread & a 2nd MP40 seems to have been on a wish list, but have you made that purchase? Not sure if you turn pumps off when you take photos, but on a couple of your pics showing the water surface, there doesn't appear to be a whole lot of flow/surface agitation. I have 3 MP40WES on my 77, one each end, one at back in EcoSmart TSM mode around 80%. Only a couple of SPS, mostly softies & LPS. I would think on a 90 mixed reef running only a single MP40 & a MaxiJet, more flow might help solve the slime problem?

I have the Mp40es, a Maxijet 1200 and a Korallia 1400 as well as the Eheim 5000 return for flow at the moment. That sums up to about 6000GPH flow which is over 65 times total display tank flow and in theory more than enough flow for an SPS display. I don't doubt lack of flow near the sandbed though so perhaps this is truly the answer.

I have a pair of MP10s; one on each end, centered top to bottom, and about 5" from the front. I run them on nutrient transport @ 75% and it's enough to keep my sand clean

Wayne, try to solve the cyano issue before adding more flow as, once you have it, adding flow will only feed it more. Once it's gone you can consider making flow changes as higher flow helps keep it away

it'z a type of cyano
