I think you want to look carefully at your actual organic balance in your system.
Peel back all the layers of cheatos, mechanical filtration and whatever else you have going on to control your nutrients.
Objectively see your input and output of nutrients with rate of tank water turnover ratio.

Anyway I have ramble on too much now.
Do I know why I got cyano?
I would assume it has to do with my no3 and amino additions after my nutrient reduction.
Personally, I don’t believe there is a unified theory as to why cyano shows up, nor a nutrient ratio that will actually cause it. There are just too many variables and chemical processes going on in a reef to pinpoint any one cause.
I’m not sure I know what ‘peel back the layers of cheato, mechanical filtration and whatever else you have going on to control your nutrients.

Once my fluconazole treatment is done, I will do a good clean out of detritus in my frag tank and fuge, removal as much cyano as I can from the frag rack and add some carbon. In the mean time, my cheato will be working out a new balance now that the bryopsis is gone.
If the cyano remains with my aminos and no3 additions stopped, I will does a slime remover... or maybe try wally’s Method of zeobak and coral snow.. although I already use AF’s version of coral snow- Build..

I didn't know you are doing the fluconazole treatment.
That is your source of problem with the bryopsis dying and short burst of nutrients explosion. Which it happened to me on my previous tank when I did the same treatment.
It will go away naturally in about 1 month if you left your cheatos to their job.

I do believe there is a good ratio of N:P to stay within to keep the tank looking clean. 22:1 is the magic number that I have come up with after many trial and error. Corals really pump hard with growth and colours if I am feeding that ratio. Which doesn't cause algae bloom issues.

I think i will let the cheato do its thing and not mess with no3 for a while..
Ill see where n goes... i expect it'll drop back down to next to nothing.. maybe ill just let it go this time..
maybe p will follow.. maybe not.
I haven't really just let the tank work itself out..
I'll do that this time..

Never had good luck with Chaeto or any macro algae. Got tired of the nutrient seesaw. Algae would grow like crazy and nitrate and phosphate would bottom out. Algae would die back and nitrate/phosphate would rise once again.

Not worth the parameter swings at the end of the day.

I find it more of a balance thing, dial back your lamp hrs on the cheato or use smaller amounts and pull out more growth more often until you find what your tank balance is...

I have experienced more than once chaeto growth stagnation but never died chaeto. IMO when chaeto die the cause is not the lack of nutrients but the lack of something I can not determine. I have a 20g plastic drum full with chaeto ,just a 6w lamp above it and sparingly fed, for amphipods propagation, and surprisingly chaeto is not dying, just not growing.

Just another parameter to worry about. To each their own. Chaeto is a ticking parameter time bomb imo. I'd rather test for nitrate/phosphate and run some gfo and control my fish feedings and water changes.

I think that sometimes it's the best call.

Agreed 100% - not sure pulling works unless you really reduce the quantity of cheato, but reducing photoperiod will certainly reduce its efficiency.

Agreed also.. I don’t think it’s the nutrients (alone) that have an effect in cheato. Cheato, like zoox or any other plant (freshwater or marine or terrestrial need a group of nutrients/minerals to be happy- ones that I can think of: iron, zinc, manganese, potassium, iodine as well as n and p.. You’ll find these in almost all plant fertilizers...
Maybe plants from different environments have different requirements but I think some are universal..

To each their own, for sure.. I have never had success with carbon dosing. Or gfo usage for that matter.. And I’d say that Carbon/gfo usage is as much of a ticking time bomb and/or parameter swinger as any nutrient method, when not properly managed.. and I’d go further to say that cheato moves nutrients in a more gradual manner than gfo and Carbon. An like everything in reefing, once the balance is reached, easier to monitor/maintain.

Yes.. I will observe this time and watch for a while when n drops out. I won’t immediately reach for the nitrate bottles..

Matt -- For me, cyano comes when my nutrients hit zero. It seems in my tank, nutrients allow more dominant life forms to take over where cyano normally would.

Every tank is different though, and one thing that surely seems to mess with cyano is heavy flow. I'm of the belief that 'too much flow' is a non-existent fairy tale. You could probably double your flow and see nothing but happy corals and fish developing muscle
