that is cyano and it can come in a range of colors. cyano is a universal reef tank invader, 100% of active reef tanks in the world have it get into their tank everyday via various means. the ones where it expresses as a sustaining colony have nutrients stores, wastes or elevated dissolved nutrients in the water as the ongoing cause. its true aging CC takes on and holds waste, that is a playing factor agreed. if the tank was mine id simply disassemble and clean out the whole tank and put everything back in/reacclimate and be waste free. id use smaller grain bed or no bed at all, just my take. cyanobacteria hold the title as the true ubiquitous reef tank invader, you could set up a reef tank in the middle of the gobi desert and if you kept it functioning cool somehow lol, cyano would still get in. this is not algae, its a bacterial/moneran mat.

Well crap.... now I dont know what to do with my fish and corals. .. but I do know I cant handle the black stuff so guess I will have to figure out something ..

 

[lewis.maryann08]

Would it do any good to vacuum everything out of the bottom and replace it or is it in the water?

So many opinions that's true...this is mine

My tank is immune to this and all invaders all the time by specific actions. the same cyano gets into my tank ( reds are selected more in my setup, still cyano tho) but will not express for two reasons:

When the tiniest bit is detected I'll not only rip that out in an immediate and giant water change, but I'll clean the entire sandbed in the same cleaning run... I'll hit the fuel. I'll never dose chems to beat it

For sure various clean up crews, chemiclean, and flow adjustments are the main go to.

But my reef is immune, and it uses none of those, so I gotta stick with the 100% and even though an easier way likely exists, the 100% is the only thing good enough for me. Many options exist and one is always great, but harder to attain the larger a tank gets. People tend to not associate cyano mitigation with deep cleaning, so it persists more for the dosers and the hands off, imo

It's harder to deep clean a larger reef so hands off water dosing tends to follow. Keeping your tank free of detritus and unused feed cuts off cyano the best, imo and then other easier methods vary. I'd simply siphon remove it twenty times if twenty was required.

Stirring up the bottom to much at one time can be harmful. The problem is with crushed coral is that detritus can slip between all those pieces and lay dormant and be a problem for nitrates also. Just suck some water into a small tank with a heater and air stone and sponge filter and transfer wildlife. Drain your tank into a large clean trashcan then remove rocks and crushed coral replace with a live sand or leave barren put rocks back in pump water back in and run for a day or two then transfer fish back in.

Agreed, be thorough if you are going to act, and separate your delicates elsewhere before rip cleaning nice call. Reuse of the cc simply means you'll do this again later. Bare bottom avoids this repeat totally if u like that look

I use a ridiculously oversized sandbed in my tank only because I'm willing to repeat as needed.

I went over and snapped a pic of my nano with a golden hue cyano mat forming, I've been lazy on wc and have overfed this cycle, so an attack is commencing and in thirty mins I'll have a brand new reef ten years old



What would most do? Hit it with chemi clean or up the flow. I just can't accept actions that have variable outcome.

 

[lewis.maryann08]

Thank you for all your help I think I will clean it out and start with some fresh live sand what about my live rock do I née to clean it some way?

 

[lewis.maryann08]

Will my tank have to re cycle when I put all new live sand in it?

No recycle

I show using my own tank in this link below how to flip clean a sandbed with no recycle, that little tank is the reefbowl
Delicate. It's been flipped a thousand times. We are doing yours once, it's a good little shock value pico example for sure.
http://www.nano-reef.com/topic/3622...ico-reef-last-full-tank-shot-before-cleaning/
I'm 100% sure no recycle


before we do it I'd like to see all details
We can plan before any action.

I'll link this thread here of your tank to my large peroxide threads as a cleaning reference even though we don't need peroxide in your tank if you want to power clean it

Your tank will not recycle and nothing will die if we do easy order of operations
We need to see the whole tank for a total plan, I'd rinse everything is saltwater including the rocks because it removes waste and doesn't remove bacteria as in sterilization.

Look at what non cleaning has done in this thread:

https://www.reef2reef.com/threads/accidentally-started-a-mini-cycle-cleaning-sandbed.225370/

You may not even have a waste loaded sandbed perhaps your cyano rebounded off a days bit-too-much feeding or a few lacking water changes...but with full pics for sure we can clean this tank and remove any waste if it needs it.

If all this is overwhelming, some just try some chemi clean before going to town, not everyone wants the deep scrub

Many threads have involved deep access lately, whether as moves or upgrades or algae cleaning runs, popular topic lately. Post full tank shot if you can
