agreed its lots of words
quick summary:
1. we test rock most attempts. all other forms of anti algae work affect your entire system, and usually require one to change out nutrient levels where corals were doing just fine. We are an action thread, I don't need to Identify your invader nor know you nutrient level details to make your aquarium free of an invasion. The sand rinse thread handles all non anchored invasions, below, and this thread here handles all anchored invaders because we use test rocking and rasping along with peroxide to truly affect a win
sand rinse thread, not possible to have cyano issues after going through this.

2. Test rocks and rasping.
For most presented invaded tanks, we need to learn about your invasion specifics and how they interact with variables in your home; lighting, c02, nutrient levels though I don't care what they are, we need to see how well the invader responds to some detail work. we use a steak knife or a hard metal tool/brush, to score off areas of the algae outside the tank (a test rock is lifted out) and the knife action makes the spot free, some substrate is scraped and damaged like a rasping organism would do on a real reef (parrotfish, urchin etc) we put peroxide on that spot after its cleaned, not before, as a final burn cleaner of plant cells.
rinse all that work off with clean saltwater, put the test rock back in the tank and lets chart what it does a few days or a week before massive work. That is a test model which gives any invaded tank a personalized approach. If we need to dose the whole tank with peroxide, rare, then you can use a paint bucket and the known dilutions on a test rock before you proceed.
3. Doing any form of algae work while you have a sandbed that cannot pass a drop / clouding test from my sand rinse thread is the greatest waste of time in history. Attack your algae from the bottom of your tank, up, as work will save you and non work got you here.
4. 35% peroxide is dangerous, but needed in some invasions depending on test model performance and level of catchup work done. It is a blinding agent, totally dangerous, and shouldn't be kept around small kids. 35% is all I used when I needed to fix up an invasion, carefully, bc its so fast. 3% works well enough that we are safe with it, and 90% of tanks respond just fine to 3% normal solution.
5. Peroxide is not a never ending wheel. Actually attacking an invader can stop them from growing, though you've been told that wont work. You are doing work on top of a clean sandbed, with no nutrients for them, of course a direct kill is part of the actual solution along with that greater action. Cyano and some limited species of green algae are permanently associated with reefing, so when they show up we don't see bad, we see a keeper who allowed natural events to take place and they either want it killed, or not.
6. Sensitive organisms to peroxide: lysmata cleaners, fireworms are super sensitive and w die within the rock work at times, xenia, decorative macros and coralline might stress. Posts here show we can work around those, and we being with test rocking for that very reason, it doesn't contact such targets.
7. all known reefing fish are not sensitive and many have endured massive overdoses (accidents) and survived, I know of no commonly kept fish that are sensitive.
post us a bunch of pics! we are pic heavy here
