It looks like cyano to me... But honestly it doesn't look too bad. Have you tried just manually removing it all?

 

[Edgar Melton]

yes i have and it comes back worse i siphend 80% out yesterday and did a 20% water change and killed the lights came back even more

Looks like cyno to me as well

 

[Edgar Melton]

yea thats what i thought but why is it growing so fast in the dark

Clean your bioballs, sump and Skimmer if u have one. Six months in... its time.

 

[Edgar Melton]

i clean my skimmer onec a month cleand the sump maybe 2 months ago and i have no bio balls

what are your perams at?

It looks like cyano to me. mine took about 5 months till i beat it, i did a ton of water changes and just kept at it.

 

[Edgar Melton]

all my per are reading fine but i must have phos or nitrates just not getting a reading on them and i only feed onec a day

How old are your test kits? Definitely cyano. Get a phosphate reactor

 

[coastalpt]

Biopellets?

 

[Edgar Melton]

they are api not the best i know not old at all im running gfo reactor for 2 1/2 moths now 1 1/2 cups of high cop gfo from bulkreef sup im trying the lights out for three day see if that will help

 

[Edgar Melton]

no biopellets

The cyno will consume the nutrients so your tests will not be effective.
It takes about a year for a tank to mature.....
Try to manually remove as much as you can and keep up on water changes.
You need to find the cause of your nutrients most common is over feeding.
Adding additional flow or redirecting your powerheads to increase flow to the areas with the algae may help as well.
