Thanks. Do you know if its about the same size, smaller, or larger?
There's different brands of pool filter sand and some have bigger or smaller grains. 3M Colorquartz is the size of the Home Depot pool filter sand (not the playsand). It's pretty fine but it's heavy, I love it. The Colorquartz T grade is more granular (sharper). Not sure if it's enough to make a difference to sand sifting fish & plecs as I've never used the T grade.

Thanks. I really like the size and weight of the pool filter sand I have, from leslies pool supply, but the color is a little too light colored. How often do you stir your sand? I dont completely stir my pfs very often and I havent had any issues with anaerobic bacteria which is another reason why I like it.
I syphon all through it with every weekly or bi-weekly water change. The whole idea of anaerobic pockets in sand is pretty debateable said to be one of those myths that won't die. I'm just repeating what I read, don't want to debate it 
And I agree-most pool filter sand is way too bright for my tastes.

Thats about what I am doing now, but I have heard things like sand needing to be stirred every other day with play sand, and all sorts of other "ideas".
The pool filter sand isnt super white, its got a lot of variation and looks pretty good, I am just thinking about adding some dark s grade colorquartz to it to darken it up.
S grade Colorquartz averages 0.21mm or .008 in size. I think the average pool sand grain is .45mm to .55mm for #20 grade.

Where did you find that info? That would make it 1/4 the size of 20 grade PFS grain size.
On the 3M website at the MSDS sheet. http://solutions.3m.com/wps/portal/...tn&q=colorquartz&num=10&search=Search&snum=10.
The size variance from 0.21mm to 1.7mm is for the S grade & T grade sizes.
