Microscope for ID?

[BadCrab]

I've been battling this fast-growing substrate-covering nuisance for a few months now. The war has ebbed and flowed, but it's currently winning.
I'd love to get a positive ID to confirm my direction. I'm reasonably confident it's a green cyanobacteria, but I haven't seen its structure because I don't have a microscope capable of that magnification. Does anyone here? I can bring a sample to you.

I have elevated my nutrients to detectable levels (PO4 was bottomed out for a long time,) by dosing NeoPhos and feeding the shrimps NLS pellets a few times a week. I'm dosing Microbacter7 as well. I can vacuum this stuff out only for it to be fully returned in 48 hours. Frustrating!

I ordered a bag of CaCO3 from Amazon after another reefer recommended dosing it. This acts like a flocculant for bacteria and tannins to bind to it, allowing mechanical filtration to pull it out. It can be combined with amino acids for coral food or microbacter to outcompete cyano.

Happy to hear if anyone's had experience with this (DIY KZ Coral Snow) but otherwise I'll update the thread once I've had a chance to deep clean and dose.

Funny you mention a microscope, as @Pwhitby was recently discussing a "microscope meeting" with me for a future club event. So, the club may have one soon, but that doesn't meet your immediate need.

I've always had good results using Dr. Tim's products on this sort of thing.
