ID please??

Currently my nitrates are reading 5 with salifert and my phosphates are reading 0.03-0.07 with Hannah ultra low phosphorus

Sps polyps are still out but not as much as normal and for some reason my Duncan's and torch corals are not having good polyp extension also....

I think it is related to what's growing on my rocks and a couple of my sps corals....

I blow it off every day and it comes back the next day....it is growing in high flow areas also, so it's not lack of flow...it is not growing on the sand really, just in random spots of the love rock and on some powerheads....

Any help would be great!! Here are some pictures and let me know if you need any other information or more pictures! Thank you!!

Looks like some cyano to me

I was leaning towards that also....but just wanted to make sure!! Chemi clean? I do routine water changes.....

This is also growing on my chaeto for some reason....I have slow flow in there also....I blow it off and grows back the next day...

Maybe cut back a bit on your feeding if you feed more than once a day, also be sure your lights arnt running for more than 12hrs a day in the display. Have you had any new additions to the tank or anything you can think of that has changed recently

I run my radions from 9-10 but only 6 hours of it being at it's peak which is only 65% intensity, both blues and UV are at 100%, green and red are at 0% and white is at 25%

I also run 4 T5 Bulbs with the radions for 6 hours a day ...2 blue plus and 2 coral plus

As for feeding I have 20 fish in about 260 gallons of water, most fish are anthias size or smaller....and I feed once a day

I've also added in some good bacteria to see if it could help but it hasn't done anything in the last week....not sure if I should keep doing water changes, just keep blowing it off every day, or get chemi clean or something

Some chemi clean wouldn't hurt to try, i myself am in sort of the same boat with some nuisance cyano right now. I had to clean multiple rocks of overgrowing mushrooms which in doing so i scraped off most of the "live" portion of the rock

 

[Gwitness]

Dang! Yeah I can't pull out my rock, I've got to try and solve this without taking stuff out....I've got too many corals, there is just no way I could do it rock by rock unless I have no other choice

 

[Gwitness]

I also hate doing chemi clean because I feel like it's just a band aid over whatever my issue is

 

[Matthew Dambra]

My cyano was a result of removing the rocks and cleaning it from the mushrooms. Are you lighting your refugium 24/7?

 

[Gwitness]

I'm lighting it about 15 hours

 

[Matthew Dambra]

i run my refugium 24/7 maybe try that and see if it helps

 

[Gwitness]

Okay I'll give that a shot and maybe it will help! I also turned my supplement t5 Bulbs off so I'll let the radions run by themselves for a couple day and see if that does anything

Anyone else have any ideas on if this is cyano, diatoms, or Dino's?
