I tried numerous approaches to rid cyano from sugar dosing which is a carbon source to manual removal. I finally caved and used medicine the cyano disappeared but the clams didn't like it and in turn lost all the clams as a result the tank turned into clam chowder and I lost 90% of my sps. $6000 in livestock down the drain.

Not trying to scare you but from experience will never use any Meds on my tank ever again. Try the filter sock and turkey baster technique to alleviate cyano or even adding mb7 which should out compete the bacteria.

Good luck!

Every emerald crab died within a day for about a year, the LFS switched supplier and we now have 4 alive and well and chowing down the past month so the Valonia isn't really worrying me especially since I decided that scrapping the stuff off would probably not make things any worse than they already were. The cyano is better but I'll be doing another 3 days lights out in about 2 weeks to bring it down more. I'm doing about 15-20 gal wc weekly right now and that"s after blasting all the cyano off so I can siphon it out as well as as many bubble spores as I can get.
Thanks!

Are these the ideal parameters for these?

Calc seems low but I've always kept mine high for all the sps...
Never had a problem with using chemiclean for cyano.
Although in your case the nutrients released would require heavy skimming and water changes. Do you grow chaeto or run pellets to help with extra nutrients?

[Emeraude1484]

I was debating using chemiclean but I just got a Mandy and I heard that it will essentially wipe out my copepod population so that will really be a last resort. A few months ago chaeto was running rampant in my DT which I'm thinking might have to do with my issues now since I ripped it all out. I don't seem to have much extra nutrients though. I feed once a day either pellets or half cube of mysis.

cheminclean don't do a thing to the pod population. It does not do a thing to anything else but cyano.

I used it from time to time to make my water crystal clear. It just make your skimmer go nuts so be carefull with this and sometime you have to remove the skimmer cup and let it run like that just to keep the water oxygenated.

It is not good to stop the skimmer if you don't have to so removing the cup often is enough to be able to still run it.

If you have that much problem with cyano, I don't beleive that you have 0 nitrates and phosphates....pretty much doubtfull.

Use the Redsea nitrates and phosphates test kit and see the result...you probably have a lot more than you think.

the cyano don't stick on healty coral. If it stick on your birdnest it is because the flesh on it is already dead and gone, maybe from something out of wack with your parameters? could be copper if you keep loosing your crabs?

All the other inverts were surviving. And now that the LFS has switched suppliers I have 4 happy emeralds If fixing the parameters in my tank doesn't fix the cyano issue I may look into chemiclean thank you for letting me know your pod population did fine. Gives me another option
