How long to leave quarantine tank alone?

[daniella3d]

yes it's the safest minimum for most parasites with cycle.

I read that the ick cyst can life up to 71 days but that is extremely rare. 99.9% will be dead by 60 days. So 2 months is relatively safe for most parasites. If you want to be 100% sure, then 3 months but I think that over doing it. In case of something severe like marine velvet, I would go 3 months.

I would definitly NOT wipe a tank that is established for 2 years..what a waste. YES cycling would take maybe less than 8 weeks but it would be a young tank still, not a mature and well established tank that it is now. It's best to wait. Those disease that don't need a fish to live are not a problem for fishes. It takes 2 years to get a mature 2 year old tank. That's a lot of time. Think about all the micro fauna that is established and thriving, and sometime this is very important for the fish we put in our tank and that need to eat these pods etc..
