Sand for wrasses in quarantine

[mfinn]

Sadly I have what I suspect is ick in my display tank.
At the moment I am setting up a large quarantine tank for surviving 13-14 fish.
I have 3 meleagris wrasses and 2 potters wrasses and a melanurus wrasse.
I plan on putting a large container of sand in the bare bottomed tank for the wrasses.
I am looking for a sand that will NOT absorb copper.
I used aragonite sand in my small quarantine tank last time I had the potters wrasses in it and experienced a huge drop in copper levels that I can only explain by the use of that type of sand.
I ended up rushing the copper treatment and resulted in ick being introduced into my display tank.
I saw someone mention once a type of sand that would not absorb copper.
Anyone have a clue?

Thanks

I use Fiji pink dry sand. Almost zero absorption with copper. Just rinse it well before you put it in your tank. It's dusty stuff.

Also a good idea to toss the sand once a week. Keeps the nasty stuff from fermenting in the tank. ;)

It appears to be aragonite.
Won't that absorb copper?

Yep. That's the stuff. Very fine and usually dusty as @HotRocks posted. Rinse, rinse, rinse.

I'm more worried about copper absorption than the dust.
My last round of running wrasses in quarantine using a aragonite based sand had to be the reason a large drop in ppm copper in the qt.
Just trying to avoid the same situation.

I've used Fiji Pink in the QT while dosing copper for wrasses. No problem. This specifically is the sand I used in my DT, and QT while dosing copper:

I was thinking maybe a silica based sand.

Well maybe I'll place a order for from Marine Depot. They have a 15 lb. bag. Don't really need any more.
Plus they have reagents for the Hanna Copper tester.
I got a feeling I'm going to be doing alot of daily testing.

I’ve used this to quarantine 3 leopards and a yellow coris wrasse. It was cheap and available in a 10 pound bag. I didn’t see any impact on copper levels, using the Hanna checker. I did rinse it thoroughly before use.
