It did not work for me. Perhaps the concentration or dosage was too low? The flatworms seemed entirely unaffected in the
Dipped some more test pieces today in the Bayer Insecticide.
I amped it up to 5ml in 1/2 cup for the first dip. I tested a red planet frag and a tricolor frag. Dipped for four minutes. The flatworm appeared to be dead, so I dumped the water out and then rinsed the frags with tank water. I pulled the frags out and put them back into the tank. I went back a few minutes later and the flatworm was moving again! These are some resilient little suckers!
For the next test, I doubled the dosage to 10ml in 1/2 cup. I used a $500 efflo and pink lemonade frag for test pieces. I dipped for five minutes and then pulled the frags out, rinsed, and then refilled the cup with fresh water to see if the flatworm would come back to life. After ten minutes - no movement! I conclude that, as long as the frags survive, that this will be a very effective treatment.
Color is good and all pieces have as much polyp extension as they did before the dips.
My plan is to dip every five-six days, depending on how the corals respond. I've got to pick up a couple containers at Walmart to dip in. They are the big round 16g containers. For $7 bucks, they should work pretty well to dip in. I'll probably pull the MP10 off of the 40B so I have some flow in there as well.
