i also dont understand why 6 weeks. because the whole point if to let it run it's life cycle without a host, then die without laying eggs from lack of said host. the whole life cycle takes like 7-11-ish days. so why would you need to wait more than, say, 3 weeks to be safe? thats about TWO life cycles. the second of which shouldn't even happen. I'm confused. I understand longer is better just to be safe, but I still am completely confused as to who (seemingly) picked the number 6 out the air. I know the eggs can lay dormant in the sand for a LITTLE longer than usual sometimes, but theres reports of eggs hatchign 3 MONTHS afterwards in same rare cases, so if you jsut want to be careful, shouldn't we all have to wait 3 months before adding the fish again? or to put it in perspective, a quarter of a YEAR????
