Question on Substrates

[heidii]

Hi, everyone. I will be housing a new hamster in the next couple weeks so trying to get a cage sorted right now. I've been looking into a few new substrates as I do want to try most commonly kept items in the hamster keeping hobby just so I can formulate my own opinions really.
I know Megazorb gets used by quite a few people, so I bought an 85l bag of it to try it out myself. I know some people find it too dusty, but personally I've found Kaytee and Fitch to also be really dusty, and have had to wipe down the glass panels on my cages due to the dust. Has anyone used Megazorb before, and if so, how do you feel about it? If it's too dusty I'll find another use away from the animals for it.

Also, I was looking at sands as I've only ever bought one bag of sand that I found to not be dusty at all. Komodo was horrifically dusty (or at least the bags I got) so I bought the Exo Terra red sand. It was perfect, so when it ran out I got another couple bags, but this time it was really dusty. I don't want to use play sand either.

I was looking online and found some reptile sand that was actually "silica sand". That doesn't seem massively safe right?
