I just ordered ATI Fiji white sand with a grain size of 2-3mm, I didn't want to go lower because I don't like having sand flying everywhere as soon as I turn up the flow. However I'm starting to wonder if this isn't too big for sand sifting gobies since I'd like to get one later. What do you guys think? If it's too big would it help mixing with a finer sand or am I just doomed to get finer sand for the whole tank?
Thanks!
Thanks!
