QT is the single most important thing involved in running a healthy tank. If you do not have a QT tank and inform yourself about the various coral pests and predators you will eventually acquire a pest or predator.
ATR has had the flatworms in those tanks for quite some time now. They have been treated on several occasions without success.
On the first occasion each tank on the system was sequentially removed from the system, all corals removed, and treated with a 2x dose of FWE in both the container holding the corals and the tank they came from. After one hour the tanks were siphoned/gravel vac'd of all water and debris and returned to the system. After carefully swishing the corals in the treatment bins they too were returned to the system. 1-2 tanks were treated per day for about a week and then the entire system was treated with a 2x dose of flatworm exit with normal water change and carbon usage as per the FWE instructions.
Despite the thorough treatment and the subsequent usage of FWE during acclimation of all new corals some of the flatworms survived the treatment.
The systems were treated a second time with a 2x dose of FWE a month or so later. Some still survived. At this point I am considering a 5x dosage of FWE and loading the tanks with wrasses.
Customers are typically informed and we have FWE sitting on the counter that we offer to add a drop or two to the bag to kill the flatworms during transport/acclimation. We would add the FWE to every coral that is bagged except we do not know the transport time of every coral and do not wish to cause any losses due to toxins accumulating in the bag during a long trip.
It is standard practice at ATR to dip all incoming SPS in TMPCC to prevent the introduction of RB's and AEFW's and to dip all incoming zooanthids in a freshwater and lugol's solution prior to introduction to the system to deal with any potential pests. This regimen should handle most known major pests.
Unfortunately, despite this protocol RB's were introduced to the system sometime in early December. I am not sure what led to the introduction of the RB's, but have Interceptor on hand and am waiting on the salt to do the necessary water change after treating the system (ordering from overseas can be a PITA). The system has been treated with Interceptor before for RB's, and will likely be treated with it in the future.
Unfortunately with the kind of volume of livestock that most LFS and I am sure most online livestock vendors deal with a complete QT regimen is not possible or financially feasible. This is why it is so important to QT all incoming livestock prior to introduction to a display.
