What bacteria and phyto worked for you? Can it be dormant phyto?
did you just put the mud in your sump?
My regimen after beating osteoporosis a few times already the past 18 months
UV: Run 24/7 during treatment. Oversize it. Mine is 5x my overall volume size. I run it now for 6 hours a day as maintenance during night time. It's overkill but follow the 1w per 3 gallons recommendation.
Live phyto. I started growing my own cultures because I had persistent dinos for years. Just dump a cup every night. Plus corals like having live food too.
Mud: AF Life source is served in a scooper and dosed as you would with coral snow. I just dilute it in the sump and will broadcast into the return and cover the display in gray bloom. I dose at lights out and will just clear out in the morning. Dose half the recommended weekly. I alternate this with Coral Snow after 3 or 4 days.
CoralSnow: Follow this:

Bacteria: Dr Tim's Waste Away, Microbacter7 and PNS ProBio. I dose alternately every day following dosing regimen.
Daily: Dose silicates like sponge excel. A few drops every day and start a diatom bloom. Do NOT clean your glass, let the algae and slime build up for a couple of weeks.
Live Pods: Weekly one bottle.
You can dose peroxide but I end up losing SPS frags in the process. The trick they say is to dilute the peroxide in a 10% peroxide/90% tank water mix and use the sump to dose it through the return. I didnt bother with it since I got the UV.
Skimmer collector cup is off but I run skimmer non stop back into the fuge. No GFO, no carbon.
Stopped all sources of trace and aminos-- we aren't sure what trace elements dinos feed on and aminos always feeds dinos in my tank so I stopped using all aminos altogether (especially acropower). I do add a filter pad inside the display to absorb free-floating dinos and take it out at night, replaced with a fresh one.
The strategy here is to overwhelm dino population with different sources of biodiversity which is what the dinos did when overwhelming your tank's biome. The UV kills off a ton of good and bad stuff at the same time, but you are adding and reinforcing your good biome faster than the dinos can recover. This way, it'll go back into balance. The diatoms are food for pods so it's a good thing. Cyano is handled by the coral snow. The mud adds a lot of biodiversity from the dormant bacteria that wakes up after dosing (at least that's the explanation). From my own observation, what it does is add a biofilm on the surface of rocks and sand that prevents dinos, GHA and bryopsis from having a foothold-- accelerating your tank's maturity faster than just dosing bacteria.
Hope this helps. If it's a different strain of Dinos, I would only replace the UV with the wand type since you need to nuke them in the sand. But otherwise, the strategy will still work. I never turned off the lights since I end up killing more corals that way when I tried.
