    It is a dry heat, yeah right !
    Looks like cyanobacteria to me, pretty darn common.

    Do you have any current values for nitrates and phosphates?

    What is your water source?

    Are the little white dots circular like a spirobis worm? Google image search will likely fix the spelling for me. They are harmless, but usually a sign that you have too much particulates in your water, they are filter feeders and bloom in dirtier water. If you have them, it might help to check your mechanical filtration to see if you can improve it a bit.

    Oh also +1 to cyano

    Hard to tell from the pics what consistency it is. If it's a red color and smooth/slimy then cyano. If it's more of a rust brown color and powdery looking then diatoms.
