Is there a dilution ratio, what strength peroxide, and for how long?
I used Kents Tech "M" it's a magnesium additive. Bump you magnesium up to around 1700-1800 and watch GHA literally dissolve in days. Bumping mag up won't hurt corals, fish or inverts.
Will this kill off macro algae in my algae reactor? And will it affect my other parameters in any way? Can I just bump it up with the red sea mag or does it contain too many other nutrients?
Get a bunch of snails and every night take those snails off the glass and put them on the problem areas
Which ones are best I've got a few ceriths , nassarius, nerite. Have 2 emeralds as well. Don't have a good count of snails due to hermits thinking they needed an upgrade.

Pull what you can with your hand.
blow off what you can with a power head.
Scrub with a tooth brush areas.

You can also remove the rock and scrub with the toothbrush on the algae with peroxide. 2% standard solution you buy at the store. Just dip the brush in it and scrub

It won't hurt your other parameters in any way. As far as your Algae reactor, I honestly don't know. Re: Red Seas mag, again I don't know. I was recommended Kent's Tech M by the owner of Neptunes Reefs in Denver and it worked miracles. I use Kents Tech M as my Mag additive and have now for a couple of years.

1) sell your tank, or

2) manage your no3/po4 through WCs, super oversized skimmer, and dosing a carbon-source to fuel good bacteria
Can do without 1 answer and the obvious answer you really didn't read what I asked ...

Remove as much as you can by hand, reduce white light intensity and add the following snails:
Astrea
turbo grazer
cerith
trochus
nassarius
** Pencil urchin

Is tank by chance at or near a window?

It is by our back door that has a 20ft roof over the back deck.

UV from sun is very strong and can penetrate shades and blinds and is my suspect why I asked.

Gotcha currently it's only on my zoa frags and clove polyps. The zoas are closest to the door but the polyps should be out of any direct sight of it. I was running a 10 hour day with my xr30 g5s cut it back to 8 no moon light.

Why did you put two stars by pencil urchin, do they work super well or is caution advised?

Not a snail- means also a good option

Can be defeated without chemicals
Peroxide best for GHA
Flux best for bryopsis
Sure. IMHO:

Yeah sure it is much better for bryopsis, but far from useless for GHA. Just a higher dosage 9mg/L and more days (usually 21) and it works…

I consider GHA pretty resilient, for small patches manual removal is great but when there is a lot it usually take months to reduce with nutrient control.

I cannot remove the rock from the tank and the rock has a green birdnest coral, a torch and a candycane on it. What is the best way to apply the peroxide?
