Let it settle out and test everything again tomorrow. Pick up more RODI. Hope RODI maker gets delivered. Pick up a big mixing can to make lots of salt water in, a pump for that that’s over 400gph, and a heater if you don’t already have these things. How far is the LFS? Make a few trips a day or a bunch of trips in a day and fill up the mixing container with RODI. Make good perfect saltwater at 1.025. Do a huge water change. Preferably 100% so you can get as much of the heavy metals and other bad stuff that tap puts in there. Things will continue to look mad for awhile(week or more) but they will be in a healthy environment and have a fair shot at recovery.
