setting up a quarantine tank

[Johnny Reefer]

When I QT I use 50% water from the main tank and 50% new water.
I do 20% water changes daily, replacing with main tank water.
No LR.
Filter is just a 150 AquaClear. Just the foam. No carbon.
I try to match the temp and SG of the main tank.
Water circulation is only that what is created from the AquaClear.
I medicate with Coppersafe.
The tank is a 20g.

HTH.

Cheers,
