now this is getting rediculous

[wmboots]

Ok have the new system up and running for a few months now well past mini cycle but I cannot get rid of the cyano that keeps carpeting my sand bed in a beautiful crimson blanket
Since this is basicly a new system using the rock from my old 90 with some dry marco rock my water paramateres are all spot on as one would expect.
marco rock is already covered in coraline and am getting coraline on back glass already and all corals I have put in tank are growing quite well.

So what are some other causes of cyano that I am missing?
does water flow affect cyano more than I think?

I am using a closed loop system but I am not satisfied with the flow I am getting from the posideon pump I'm using but I can't stand the sound of the little giant I was using that put out more flow but with either pump I had dead or very low flow areas in the tank.
I'm hoping to pickup a blueline from a member at the meeting this weekend that will give me a bit more flow that I hope will help with the low flow areas.
I was going to add a couple of hydor 4 power heads that I got with the tank last year but neither of them work and one of them even appeared to have never been used.

But saying all this will increasing flow help with getting rid of this pesky cyano, I vacume it and it is back the next day

1. Check water source - RO TDS (replace filters and membrane)
2. Make sure your skimmer is dialed in and skimming well.
3. Make sure you're not over feeding.
4. Vacumn as much out as you can.
5. Lights out for 3 days
6. Don't make any other changes for a few weeks to keep system stable.

How deep is the sandbed?

Just use chemi-clean (after syphoning as much cyno out as you can) and be done with it...follow directions 100%!

i have seen chemiclean work VERY well. follow the direction. my friend used it and he has a full blown reef tank. after three days of darkness and chemi clean dose it was completely gone

ChemiClean is the ticket...works great. Just follow the instructions to the letter. Better living through chemistry.

did all of the above a few weeks ago after 3 days of no lights most of the cyano was gone, so I reduced my lighting time but cyano was back within 3 days

Edit: I know most coral don't like chemiclean especially zoa's from my experience a few years ago. It didn't kill them but they sure didn't open back up for a couple of weeks. It maybe the only answer though.
Grouper, my sandbed varies from 2.5 inches to less than an inch depending on how the flow is moving the sand around

Tagging along here.

when I did mine back in Feb. just before the 75 to 120 swap the PS did not like it at all. I did not run mine for 3 to 4 weeks.

I like chemi clean, it can be a bit of a pain with the skimmer and all, but I have derived a "special" set of directions that I follow that usually has the cyano cleared within 36hrs and skimming within 24hs from then.

The corals never seem irritated.

This has worked for me also.
Sometimes it took a couple weeks of staying on top of it and cleaning , water changes and a couple applications of Chemi-clean ( use as directions state)

If you want to try a more organic method I have found sand sifting stars like to munch cyano. Might take a while though.

Well my sand sifting star is FIRED! (in my Donald Trump voice)....he's not doing his job.

Want to share your special set of directions, also does anyone know the size of scoop that comes with chemiclean I have a jar I purchased a few years ago but the scoop has disappeared

I'll PM you. Since it is not how the product is recommended to be used, I'd rather the decision be on a case to case basis instead of instructions publicly posted.

I will let you know how it works in my system, will probably wait couple of days just added a few frags yesterday and want them to settle in first even though all are fully open now

Bill,
I didn't have any issues with my zoas, sps or lps with the chemi-clean. My experience is that chemi-clean becomes less effective with age, so you might want to consider buying some new stuff if yours is old. Not sure if it has an expiration date or not, but I dosed with some old chemi-clean, and it didn't get rid of the cyano. Bought some fresh chemi-clean and it kicked butt.

Chemi-clean is one product that does what it says it does with no negative impact on other marine life, IME. Only thing I have seen is that skimmers overfoam after treatment longer than the instructions say they will.

Great point on skimmers, it takes a few carbon changes and water changes before I can skim again, usually within 5-7 days after if I am remembering correctly. But who cares?
