Algae identification

[Kirschy17]

Help me identify this algae:

Hi, my name is michael and i habe been running my tank for ~6 years including 2 moves. The tank is an AIO 65g mixed reef.

I have never had severe algae issues despite being rather lazy with waterchanges and skimmer cleaning.

I am also using a 3part dosing that also does not really work perfectly but the corals i keep all seem to be allright with the stable „easy to maintain“ conditions i have kept for years now. (For reference i have a huge montipira digita colony as well as a blue stylo besides some chalices, candy cane corals and rbta and sone softies.)

For some time now i am struggling with rather fast algae growth on my glass as well as this really ugly redish diatom/green hair algae combo on my back wall.

The red slimy thing is what i am trying to identify. I have has dinos before which i got rif of by dosing nitrate.

I am unsure if this is dinos again (theres oxygen bubbles and some slimy strings) or simply cyano? I do have very high phosphate 0.25.

Also my alkalinity is low at around 6.

I plan on starting up my refugium chaeto again to deal with the high phosphate, but i want to be sure that phosphate is causing this algae growth(if it is an algae).

I feed a variety of frozen foods sold in ice trays and always defrost in ro water and rinse the food before adding to the tank. Im not feeding corals directly besides passive feeding of the frozen food.

I have no algae on my liferock. Only some hair algae on backwall or pumps.

Im thankful for any advice or hints.

Looks like cyanobacteria. Is this photo under white lights? If not please repost one that is to make sure about the ID.

It is the same color for the human eye. I use blue light and an orange filter. (Snowboard goggles) i will ad a white light picrure too when i get home. Thanks!

Heres images under white light:
I still needed the blue filter else the image still looks blue. The color is true to eye.

I am more certain of the red mats being cyanobacteria.

Thanks on the id! In an old tank thats a sign of serious imbalance right? I will focus on correcting my parameters. I dont seem to find a lot of info on cyano in old tanks that have been running for long. Is there any agreed upon strategy for cyano?

Thanks for your time and help!

Cyanobacteria seem to grow and accumulate quite readily in aquaria no matter the age. Also, there is not much science behind the causes of cyanobacteria growth.

My approach is to remove as much as possible from the aquarium, not just blow it off surfaces. In time it will disappear. I have a rich growth of cyanobacteria in my macro algae sump but no where else. I temove it when I feel energetic.

Looks like cyano to me as well
