Changing 100% of your water at one time seems a bit extreme to me.
But is it dangerous?

I wouldn't do 100 unless you have water coming from another tank personally.
Cool. Good luck!I know the owner very well. The shops been around for years and he always tests his water extensively. I've been there many times as he's done it. I have zero concerns about this. My system is a couple years old and has plenary of live rock in sump and DT. I'll likely store 50% and change 50%, say a prayer, and see what happens. Much thanks for advice!
Well I just read this thread and watched that purple tang. Wow it was not happy. LOL I heard they were mean, but I didn't think that bad. LOL. Don't try the 100% water change, its not needed.
Onward to your problem. This is what I think you should do. In this order.
Oh no don't stop all feeding. Keep the same feeding cycle for the fish just stop the pellets for a while. I don't know what kind you use, so they could be causing phosphate issues. Just use a variety of frozen for a while. They have some outbreak as well but the corals can eat that easier and wont fall to tank floor and sit. Add some frozen brine, etc for a little bit for that beautiful tang. You can also add an algae sheet to the aquarium for feeding. I feed 2 times a day in my aquarium. Algae sheets in the morning and frozen in the evening.
Stop these immediately
1. Stop the Nannochloropsis.
2. Stop the reefroids 3x week
You don't need them right now.

Don't worry about the lighting. I would leave it the same. the clean up crew will take care of it.
Is that a window I seeAt the moment I have a 93g corner tank with a 30g sump. I'm running an NYOS 160 skimmer, a Geosreef fluidized reactor with GFO, an MP40, and chaeto and mangroves in the sump which also has Kessil H80 lighting. The DT has one 250w halide and one Kessil a360. I couldn't decide between LED or Halide so went with both. This tank has been running for a couple years. It's gone through cycles as they all do, but I can't get rid of the green algae to save my life. It grows dense and fast. I feed the tank frozen mysis and pellets daily. I grow my own Nannochloropsis. I also feed reefroids 3x week. I have loaded the sump with pods, both amphipods and copepods. My numbers are stable and show nothing special. I use RedSea Pro salt. I change 30/g per week and water is always RO. I control what I can manually with turkey baster and brushes. Also, I can't keep a chalice alive to save my life. They all end up looking like this...
When I add a new rock to the tank, it turns green within two weeks.

Here is what I would do...........Nothing. Yes, that and ......Nothing. Maybe go out for a nice dinner. Rocks with a little algae are much healthier than perfectly clean rocks. Now I realize most people will throw those clean rocks at me, but it is what it is.
I took these two pictures off a remote Hawaiian Island.
I took this off the Florida Keys.
This is my tank. That mandarin was 10 years old and spawning regularly. He finds his food there.
Don't fall into the trap where people tell you algae is some sort of disease. It is healthier than a tank with no algae as the sea grows algae on everything.
If it grows too much, build an algae scrubber but you don't want to eliminate algae, you want to cultivate it to grow only where you want it.
Never throw a chemical in there to eliminate something normal, natural and healthy.
