I don't want to hijack this thread too much, but unless you have high PO4 I would stop with the GFO. Some strains of dino's thrive when PO4 is limiting. I would definitely run GAC.
I put cyano and GHA in my tank on purpose...

It was about .25 but interesting thought, yes running GAC also

No need to worry about hijacking it’s an open discussion at this point

Interested on my end... I hate cyano and would not introduce it on purpose. At the same time if it works for you then sing the praises and let us know how it works out. I am f or anything that works. If you find the magic scenario please pass it on!!!

Day two of dosing N and P. Skimmer is ramping up but cyano is beginning to overtake the dino in some places. I’ll be testing and posting pics tomorrow. I got my Hanna refills in as well.

I’ve been keeping marine aquariums for 17 years and in any other circumstance I’d be right there with you. But in my case i want to bring as much biodiversity as i can ie a huge chunk of LR from a successful SPS tank with bits of cyano.

Test results-
Po4-.25ppm
No3-20ppm
Last dose was 0800 this morning: 12ml of flourish and 30ml of fl-nitrogen.
Same test will be conducted at 1700 tomorrow to see what my aquarium is utilizing.
Observations-
48 hours ago dino appeared to get worse and get thicker.
24 hours ago cyano is slowly taking over the sand, dino is being seen in less patches throughout approx 30-40% reduction.
Now- cyano is building up on the sand and rocks i am in a holding pattern i don’t want to make any changes to what I’ve been doing besides the dosing so that i can rule out outliers.
Light brown dino is still lingering in patches but looks lighter today.
I will update at the same time tomorrow.

Ok so it’s been 17 hours since the last test. The No3 has held steady around 12-15ppm but the Po4 bottomed our to 0 again over night. I am upping the dosage to 20ml to put me around 0.15. I’ll test both parameters again tonight.
KH is steady at 8.8
Ca steady at 440
MG steady since day one at 1440

I have battled this on and off for five years. IMO I have an issue when I don't have any green Micro algae growing. I have no green film or the tough to scrape green on the glass. I am now dosing KNO3 and PO4. My SPS love it, My Coraline is super charged, and I have a slight DINO issue Again. My cheato is going nuts also. I have backed my skimmer down. Currently I have the brown film algae and some cyano. Long story short I'd like some of the green. My PO4 bottomed out, causing the Dino to reappear, after the NO3 dosing. My next step is a large school of fish, but the quarantine will be at least 4 weeks.

I am getting the brown slime and cyano mix at the moment. I’m very tempted the do red slime remover and vacuum all the sand when i do the 20% WC after just to see where I’m at.

I just did three consecutive 20 % water changes and vacuumed all the gravel I could reach. I just started to get Dino's back after. In the past with dinos I would shut off the skimmer and stop all tank maintenance until the green got a hold on the glass. My tank was awesome until my maintenance guy unplugged my heater and forgot to plug it back in. My tank got down to 69 degrees. This is when the brown started and then took over. This was about first of January. The brown wont scrub off with a tooth brush. I'd like to turn this around. My tank is chewing through NO3 and PO4 I get them to 3 and .02 and next morning they are .02 NO3 and undetectable PO4. I have just stated PO4 dosing so I haven't nailed the daily consumption yet.

I like to take a small pump (I use this one) and use it to power wash the rock. I found blowing with a turkey baster or just vacuuming to be ineffective. Once I get it floating I have a small canister filter I drop in the tank along with my filter socks to get all the gunk out.

Get a Hanna phosphorus test. It’s well worth the money, I thought I had 0.0 ppm of phostate. Turns out my tank runs around .06 ppm - .113 ppm phosphate based on my feeding. Certain foods contain more PO4 than others. I can never read color change that Red Sea test have. Not enough difference for me. I just do small water changes weekly to correct. Been holding steady between .018 - .052 ppm doing a 5 gallon H2O change on my 90 gal.Po4 is very low
So with these numbers it’s hard for me to imagine i should have thought a huge algae outbreak unless of course it’s in balance

I don’t know if it was a coincidence but I got a really bad bryopsis out break after using A&B, took me over a year to get rid of it. Was reluctant to use Reeflux but it’s the best thing in the world. I wonder if anyone else has had problems with nuisance algae, Cyanobacteria or diatoms after use of these products.

It will come back, chemiclean will reset your tank. Cut back on aminos, 1/4 dose is a good start point.

I had a Cyno problem early on in my new build. Treated with Ultralife Blue Green Slime Stain Remover and it cleared out the cyno quickly. 3 months down the road, Cyno is back, but only in my refugium. I thought about treating again, but as long as it stays in the refugium I think it is ok to stay.
I do scoop it out of the refugium a couple times a month. I think the Cyno removes nutrients and by removing it from the fuge, I get extra nutrient reduction.

I’ve been using the Hanna for a week testing twice a day. I’m just trying to hold it above .10 at this point it’s taking 2-15ml doses in a 24 hour period. The highest it peaked was around .24.
Your experiment it is very interesting, I know for sure that thread algae in freshwater, definitely kill Cyano and different types of algae also produce allelopatics that can stop plants growth. Thi s can be seen immediately after a total water change when suddently all plants re-start to grow for a few days before going to block again.
