I went to Petco today just because I was nearby
But I remembered I had to pick up some substrate for 2 new tanks I'll be getting in the mail soon.
The tanks are one red and one blue. I tried once to use red gravel and I didn't like it so after looking at all the choices I decided to get white sand.
This is the one I got:
Looks very coarse in the picture but it's very fine in real life. It's the exact same bag, though.
Is it ok to use? Or should I return it and get something different.
Guy at Petco said it would make my pH rise but it'll be ok if I control it.
