    It is a dry heat, yeah right !
    I do not see a lot of cynobacteria in those pictures. I see some nusience green algae possible some diatoms. Cynobacteria takes on more of a matting appearence to me. You can usually remove it in sheets manually or with a turkey baster, it may appear slimmy as well . I would look at a build up of detritus in areas of the tank and sump. Good news though I do not see dinoflagellates unless you just cleaned and vacumed the system. The true test is ID made with a microscope.

    Perhaps I missed this in the thread but the spectrum of those bulbs will increase the growth of nuisance algae. That could be a main contributor to the problem of algae growth. I would look into 10k bulbs, or consider the actinics again or a combination of both for the display tank, and use 6,500k in your sump. Of course i agree the first step is fixing the salinity so you can keep a clean up crew alive in that tank because the pictures make it look like a build up of detritus. After the salinity is stable as others have stated leave the lights off since there are no corals and let a clean up crew and your water changes get the problem under control.
    oh and I agree, change your carbon too
