I'm also guessing I shouldn't run my skimmer anymore haha.

Final question. Should I target feed these guys til they get color or just broadcast. (Powdered food and amino)
Thank you for the information. My biggest push to removing the skimmer is that in my experience on my nano tanks they have always lead to an environment devoid of everything resulting in a massive dino outbreak. Since removing my skimmer on my 10g I've not seen dino. I'm going to rely More so on water changes as I don't feed my tank much in general even with fishIf you are sure that you need to chase nitrate, then do other things as well so that you can find an actual solution. Micro has no ability to use nitrate, so having more than a trace is worthless to the corals and zoox, but can do some other things for your tank like poisoning dinos, matting bacteria, grow macro algae and other. Ammonia/ammonium is where zoox get their nitrogen, so feed more and have the fish do their thing. Most people who have high nitrate who got them there by feeding just don't realize that it was the available ammonia/ammonium that made a difference and not having higher nitrate - they could have removed all of the nitrate with macro algae, or whatever, and had the same experiences. Throughput and availability is where the prize is, not residual levels. There is a large group of parrots whose first posts are about "nutrients" when they no idea what they are really posting about or what those things really do and do not do.
If you have even 1 or 2 ppb on a Hannah Ultra Low Phosphorous Checker, then this is enough. More won't hurt to a point, but after a while, calcification and be limited.
Most color issues are because of light - lack of spectrum, usually, moreso than lack of intensity. The biggest issue right now is people running too much blue for too long. You need other colors to color coral. Every bit of spectrum from 350 to 850 is usable and the more than you can supply this, the better the colors will be. In general, use daylight to render color in coral and then blue-it-up to your eyes delight for viewing.
The skimmer is a super important piece of equipment. It removes metals bound to organics and also does gas exchange. I strongly caution you to not stop running it without understanding the other things will be missed.
You can likely just make the corals look better by feeding more and also
Salinity is set. I recalibrated and tested,What are some causes:
False salinity where salinity is higher than your gage is showing *calibrate)
Too much flow
White light intensity too bright
Red Bugs
Alk spike or too high
Mag too high
Insufficient nutrients
High nitr5ates or phosphates
Testing will answer alot of chemistry concerns
It's not technically bleaching as we relate it to acropora. Bleached typically means lacking pigment and is usually associated with a stressful event. You're just lacking color
Technically bleaching has nothing to do with pigmentation/ chromaprotiens, Bleaching is the expulsion of zooanxthelle.
Acropora can look vibrantly colorful and still be considered bleached.
It most certainly CAN be the very low levels of N/P causing OPs corals' zooanxthelle densities to be low- which is what appears to be what Im looking at.
