not too bad, i am thinking its the rocks leaching absorbed nutrients back
Wat u think jus do a weekly water change an keep my parameters in check an run lights for 5 hours for another week ?

Yes I did replace ny T 5 got 2 new blue an 2 new whiteas long as there are nutrients, the cayno will grow.
Better to fix the problem. In the long run.
What filtration are you running.
You did upgrade your tank flow rate? And not using old T5 tubes.
too lazy to reread 3 pages of info. Sorry.
But if the cayno is now less, yes you can start to increase your light schedule. An hour per day every couple of days. If you got corals, they will not like the short days eventually.
Ok before embarking on some miracle cure and blaming everything and changing your complete filtration consider the following facts.
Cyanobacteria is a bacteria and requires certain conditions to thrive. Note the word "THRIVE".
Cyanobacteria will always be present within your tank.
Cyanobacteria requires food to survive.
So what is that "food". Let's look at the "food" issue first and what it could be. I am talking about the Cyanobacteria's food. Nutrients come to mind as does phosphorus and carbon...?? Without any one of the pre mentioned Cyanobacteria cannot thrive. So it makes sense, that to control Cyanobacteria, one way is to eliminate one of the pre mentioned. Nutrients, phosphate or carbon. Achieve this and your Cyanobacteria issues are over. Are they???
Well we dose carbon in some source to promote bacteria nitrification which will also feed Cyanobacteria, right. So if we reduce the carbon source to eliminate the Cyanobacteria we also reduce the carbon available to the nitrification bacteria that reduces nutrients. Some might say but I don't dose carbon. Well whatever filtration system you employ you dose carbon. So eliminating carbon is very difficult. But a consideration in the web.
Phosphorus is often considered as the easiest to eliminate and control. Hmmm.... Depends if we are talking P or PO4. This is a complex subject all on it's own, so to simplify we will talk about organic and inorganic phosphorus. Your test kit will measure inorganic phosphate and not organic phosphorus. So by adding whatever phosphate sponge/chemical and getting the PO4 down to "0" you still have P, organic phosphorus bound to.... Algae's, corals, substrate, rocks and any crustacean's ... This is the P that is the most difficult to remove and eliminate. It is the major cause of Cyanobacteria and hair algae IMO.
I am not going to harp on about nutrient control as there are many methods but from a Cyanobacteria and algae point of view they will grow where there is an abundance of nutrients.
Now you have read or been told that you should increase the flow and Cyanobacteria will go away. Yes it does and no it doesn't. Why you might ask...
Well if the surface the Cyanobacteria is "growing" on is hi in O2 and there is no dye off of algae, diatoms or other organisms, then there is no nutrients for the Cyanobacteria to get hold of. This is very evident in SPS tanks where a SPS colony takes strain and there is some dye off of a branch or two. The Cyanobacteria is often blamed for killing the coral where in fact the dye off of the coral flesh caused "food" for the Cyanobacteria.
There is another consideration, and that is silicate. Silicate is food for diatoms and diatom dye off is food for Cyanobacteria.
I am sure that what I have typed will not fix you Cyanobacteria issue but it will give you some incite on what to look out for and a bit of an understanding how the Cyanobacteria works.
Thanks for that indept look at cyno
I use sea chem carbon along time ago but that was about 7 months ago an have not used it again I agree on surplus nutrients being in my water column I have been dosing seachem fuel aquavitro I think tge surplus nutrients may have come from there since I seem tge first bloom of red cyno I stoped dosing fuel an trace an plankton
was thinking of using nopox by red sea but its best finding the causes first ....
KYes, most of the nutrient "bacteria" enhancing additives contain methanol (carbon) to feed the bacteria within the bottle when dosed. (Not within the bottle) This methanol will also feed Cyanobacteria until the bacteria reduces nutrients and Po4.
What I am saying is that the products will/may initially cause Cyanobacteria but as soon as they colonize, they reduce nutrients and out compete Cyanobacteria for the carbon source.
