This is an AIO so fuge is out of the question. I have some chaeto in the back chamber with some small LED lights but it's not growing. I have another tank with a sump and UFO light but can't seem to get chaeto to grow either.

Is that in the range you expected?
If not, try rinsing the vials out a few times. I got a few results that were super high at one point, then it went back to normal. I'm still not entirely sure why. TLDR, re-test a couple times to confirm.

Got a skimmer ?
Iv had success with phosRX or Brightwell phosE. Follow dosing instructions aka 3 drops to cut phos in half from X to Z.
Someone made this awesome calculator, i use it myself.

I'd second ensuring you perform the test a few times to make sure it wasn't a fluke or user error. Assuming your tank doesn't normally run at this level, I would bring the level down SLOWLY. You can increase your frequency of WCs, add a refugium, algae turf scrubber, lanthum chloride, gfo, etc. There are a ton of ways, but all require you to go SLOW 
. Also, make sure you look at the other piece of the puzzle- the nutrients you are adding to the tank. Often, this is the first place to start- looking at overfeeding, supplements, or coral food. Many contain extremely high levels of phosphate.

So what is causing your phosphate levels. What and how often are you feeding. I use a Clearwater scrubber, but that may not be an option here.
At least you probably don’t have to worry about dinos!
I second all that has been said. Confirm your testing and if it’s correct, pick your strategy and remember that nothing good happens quickly in a reef tank. Or really any aquarium.

FYI, I believe 200 ppb is the upper limit of the ulr tester. Meaning your actual phosphates are likely off scale high. I bought the ulr tester when I started testing my water, and ended up buying the low range phosphate tester (713) so that I could actually know where I stood. Phosphate Rx was my main tool to get my levels down.
Yeah, I thought 200 is the upper limit. I got this reading on both of my tanks. I have cut back on feeding for both fish & corals and just got PhosGuard. Will be testing again in a few days and if that doesn't work out, I will look into Phosphate Rx. Thanks.

GFO added into the AIO overflow for regular phosphate maintenance. However for now to speed up reduction I would try Brightwell Phosphate-E (lanthanum chloride).
