Monkey love, if you visit those threads as suggested, you'll see many of the points I'd like to make for you and save me some typing on my iPad
But what you need to understand the most is that when you have metal in your source water, you REALLY want to avoid slamming by keeping your parameters right on [fc/cya][/FC/cya]...because so long as you're working with sequestrant and a high load of metal, you will not get off the treadmill.
I used PMM for years and believe its about the best on the market for well iron in a non-swg environment. I wouldn't switch personally.
Traceing Paper as I recall did a floc treatment, which can be successful in some cases, especially when the metal is completely oxidized. Others have seen the same treatment fail completely, where the floc doesn't form...we're not sure the exact conditions that cause the failure...may be sequestrant or may be ph related

But that's why we don't routinely suggest that route at this point. You may well wish to try it. Historically, TFP guides are trained to generally avoid recommending floc in other situation for two reasons -- the floc n shock approach of pool techs kinda goes against the more informed TFP management, and floc has some nasty unintended consequences if you don't have a multiport valve to vac to waste, etc., or if you have DE and don't get it out, etc etc. With that said, and taking off my guide hat for a moment, for iron removal specifically it could in fact be an excellent if experimental strategy, in whch case Leslie's Alum specifically seems to be the preferred flc product for metal. I have done two tests with it - one worked and one failed, and I cannot determine why

So I leave you to arrive at your own decision tree on that one...
Since you still have some oxidized metals, do try to filter them out to reduce the load. Your subsequent sequestrant will last longer and work better that way. Also, see those threads for this on pre-filtering your fill water to help in metal management.
@traecing paper - I'm guessing you used these from Duda diesel?
