IMO it's time to put the chemicals on the shelf; place the diffusers in the deepest water at 2 ft. off the bottom to prevent stirring up the stuff, and give the aeration time to dissipate the excessive nutrients. It didnt happen overnight and will not be cured overnight.
Should I run the diffusers at night only instead of 24/7? I'm mainly using aeration to remove the nutrients but it sounds like I'm doing more harm than good. I also use feed but it's a minimal amount, fish eat all in about 5-10 minutes.
Have you done a jar test to see if the stain settles in 24 hrs. or if a specific amount of alum will settle it?
I did the jar test using a control jar, one with vinegar and several different levels of Gypsum slurry. I've taken care of the suspended clay by adding gypsum and shutting of aerators for a weekend.
