Another thought-
This tank doens't need biological filtration, but it was designed so it could have live sand and live rock if wanted. I think if it were me I'd make it a tank with live sand and not a sterile tank just for ammonia reasons.
If someone does use it like that, it would take a couple weeks after adding sand and rock to just make sure it is stable. At least I think I would wait a couple weeks just to be sure.
