Tough to say. You might need to wait up to 75 days for the invertebrates to clear themselves of any ich tomonts that might be hanging on them. Or there are no fish in the DT, if you can raise the temperature to 81 degrees, you can shorten time down to possibly 45 days. Then, you’ll want to quarantine any new fish to reduce the chance of this happening again.Sadly my lion succumbed to the ich, so DT is empty atm. You recommend doing a Coppersafe bomb for 30 days in DT? Will that affect my macro/micro algae + pods? Also how long until I can return inverts to main DT, and last could I add new fish into the DT during its 30 day copper dose.
