I have had good success with the DE called CELPURE P1000. Food grade, high-flow rate, ultrapure so contains less Al, Fe, Na, & Cu, and has less influence on pH. More expensive, but the purity and size consistency seems quite good.

thank you.
How did you stack the tampon under the CRC media? cut it to fit the column? fold it? Did you go 1um or 5um?

Havenāt had a chance to try it out yet. Been stuck in the planning/building stage for so long I feel like wax will be $5 a gram and available at the gas station before I ever make a run. But after reading till my eyes burn on here, I know Iāll be trying many different configurations. I like experimenting, so Iāll try 25um coffee filter followed by 5um filter paper from bvv directly below the cat nip in a jacketed 6x24 material column. Then for cr a tight rolled 2ā tall 1um tampon below B80 in a 2x12 filter column. But Iāll probably change my mind 10 more times.
I suspect one very tight lipped member on here is tossing his nuggs, shake n bake style in his remediation blend before blasting straight to recovery. I really want to try that.

You need something like DE to create an acceptable 3D matrix filter. The purpose of the DE itself is to create another dimension for filtrationāand that added dimension provides some assurance that finer particulates are adequately filtered.
Why exactly do you want to get rid of DE?

Someone recommend silikate pulver as a replacementā¦
That helps my understanding of it a bit better.
The DE is hardening against the walls of my vessel and itās requiring me to have to scrape it out when I replace the media.
My ultimate goal is to speed up reloading the media. I bought the vacuums recommended and they donāt work, they clog from the media almost immediately.
Iām going to purchase a few different types of the DE mentioned on here, I didnāt think they could come in different grades but itās worth a shot to see if maybe Iām just using a cheap brand.
This may help illustrate my current CRC breakdown- Where would you utilize the tampon?
The way I rigged it currently is when I replace the media, I just keep the sintered discs and sightglass connected to my rack, I then disconnect the column (the media stays in because I use a filter stack at the bottom)
Put the cylinder into a trash bag and carefully push the media through the column into the bag.
But the damn DE can harden and make this process sort of a bitch.
EDIT: And if anyone is curious, I have never seen media get past the filters in the 5um, I clean the 1um during the entire breakdowns and have never seen anything caught in the filters.
I vacuumed out my crc a couple days ago, no issues (3x18)
And I canāt see the picture you posted. Itās just black.

Thereās like a thousand types of celite. Using a wider band mesh celite prevents that serious sticking. Also if you are done with column you can flush to a drain tank a separate solvent to help loosen it up especially in reverse flow.

thanks for getting involved in the thread.
as i stated i am trying to replace the d.e. because i had gotten a bag that had a lot of fines that were making their way past my filters.
i ran before this bag fine with no fines and run fine now using a different source.
point being i dont want to waste time getting bunk batches.
is it your opinion that the polyester felt is not a suitable ā3d matrix filterā to filter out the medias?
