I keep getting cyano in the same spots everyday. I will stir it away but it will return in a few hours only in the same spots. My phos is .07 and nitrate 3ppm. That area does not have a lot of sand. I will be changing my sandbed to a larger grain soon slowly

Is the flow pretty low there?
The cyano is getting hit with flow in the area. Rest of the tank is fine

Elevate nitrates to around 10ppm, stir the sandbed at night and immediately add a few ml of distilled white vinegar + a healthy dose of beneficial bacteria. Your display will cloud up for a day or two, but it’ll do a number on cyano and help keep it from coming back. If you’re going to keep your phosphates where they are, try to keep nitrates between 5-10ppm.

I was thinking about it, can it upset corals? My rocks now are finally growing coralline, and have very little algae on them now
ChemiClean is amazing stuff. I had it bad in my 220....sand, rocks, etc. 85% gone overnight and 100% gone in 2 days. No corals or fish were visibly affected. Took Skimmer cup off to promote more aeration in the system.

It was like magic and it has not returned weeks later.

Same situation here. Chemiclean will work, but I have always had it come back, and only in the sandbed. Rocks are pefectly covered in coraline.

I simply suck it out during a WC into a filter sock, bleach the sand overnight, rinse in RO/DI, and prime, and let it air dry for a couple weeks, then add it back in later on.

If I don't do that during my weekly maintenance, it gets as bad as your pick.

I was considering using the bright stuff to raise them. I am feeding more. I tried to stop dosing aminos to see if the cyano would go away for a week and it didnt.

Yesterday i stirred it up and it was all white, and it came back overnight. Ive been stirring it for about a month before that with no issues on my parameters. Corals are happy and growing, its just looks ugly

I think this is good advice.
Chemical removals are fine but if you have not fixed the problem, it just comes back.
The stir did not do much for me like you said, stir to white, back next morning.

i did increase my nutrients up to 15ppm and Phos to .1.
I siphoned the stuff out every second day, it took about 3 weeks, then got less each day.
After a month I was back to white sand.
I’ve left my nutrients at the above level now for months, no problems.

I plan on increasing them slowly with the birghtwell neonitro, did you see an increase of algae growth with higher nitrates?

My DT is 3 years mature, so I have no algae anywhere.
I can run N at 25ppm and P at .2 and have no algae.
The more maturity, the more you can push nutrients and lighting.
I might have some concern on a newer set up.
I would be more concerned if phosphates increased, and you can always back off lighting a bit.
