I'll be picking some up tomorrow if the lfs has it. Do you just add the stuff to the tank, or do you gotta chase them around with it?
I used that stuff. Follow the instructions. Here's how I did it and had no problem. Have two batchhes of saltwater made in case two changes are needed.
1. Suction out all that you see. Squirt the rock with baster to check for any hiding. Suction these out also if you find any. This is very important step because you have more then you think.
2. Take out all carbon if your running a filter shut it off. But have it full of carbon when the flatworms start dying. Keep protein skimmer running.
3. Add the exit. Start off with half the dose as stated on the instructions. If flatworms aren't starting to scatter add the other half slowly. Keep your eye son the flatworms. As soon as they start to scatter it means the stuff is starting to work. As soon as they start dying start suctioning them out.
What I did is I made a net out of material because they can't go through it. It helps if you have another person to hold it. This way you'll get them before they fowl the water to badly. As I was suctioning them out my daughter was holding the other end in the net above the sump by protein skimmmer. This way the water went back in but not the worms. Also didn't have to worry about the water getting to low.
4. Turn on filter with lots of carbon. If you turn this on too soon all the flatworms won't die. But if you can't keep up with getting them out as they die you'll have to turn it on. I turned mine on after a half hour. I had them real bad but with help I was able to avoid any problems. All my fish and corals made it. The corals opened up some the next day but the day after all were back to the way they were before treatment.
5. Do water change after you start the carbon. This is when I suctioned them off the sand.
6. Test your water after the change. If all come out good you won't have to do another water change.
7. Keep carbon running for a few days.
8. Retreat after a week even if you don't see any more flatworms. I did this before a regular water change.
9. If your lucky all flatworms should be gone. But iif your like me you'll always be looking for them.
Hope this helps.
