Garnet works for me. Depends on your placement of intakes how deep your sand bed is and how much your fish kick up substrate.

I'm using garnet as well. based on the different samples sent to me that I was able to play around 20-40 is the best that ive used to suit rays. using it with ornate bichirs as well.

I've used both play sand and pool filter sand for my rays. The play sand was always kicked up into the filter and would cloud the tank from to much activity. The pfs after the first initial wash is heavy enough so that even after one of the rays stirs the sand it instantly falls back down.

I have two fx5s, a 2062 and two cfs500s on the tank right now. No issues with any design.

After ensuring the sand you're looking to use is not toxic (and really, I can't think of a lot of instances where they would be)...
You do not need to worry about the label on the bag, you need to worry about the sand grain size.

Example of grading in brand I prefer:


Most people don't seem to grasp this, so you'll get all sorts of answers. Unless the sand is specifically graded on the bag, it will vary from brand to brand (pool filter sand is not universally the same!) or even bag to bag within brands. After that it's a matter of color preference, availability, etc.

For get all the play sand or pool sand or anything else.

This guy asked for the best and honestly the best is Carib Sea Torpedo Beach

Its a much larger grain and will not get sucked into filters. Also it does not stick to rays so you get to enjoy them as much as possible. I highly recommend it and would never use anything else. If you have looked at ray pictures im sure you have seen them with sand stuck to them and how none attractive it looks.
