use flatworm exit

[bcjm]

My tank got infected lately. I want to use FWE before they are out of control. I have a 150G tank + a sump. I estimated I have about 150G of water total. I played around in a small container for a while to see how much FWE I need to use. I have a lot of mini serpent sea stars. I like to find a dosage that kills the FW but not the sea star. I put some in a 5G container with FW. Two drops FWE kill both in less than 30 minutes. A small drop makes them stressed but not dead for an hour. That means almost two drops for a gallon. The recommended dosage is 4 drops for 5 gallons but many people reported they need to use 2X recommended dosage.

 

Each bottle is 200 drops. I went ahead put in 190 drops which is much lower than my calculation but stronger than the recommended. To my surprise , FW started dying in 5-10 minutes (at least floating in the water column). Sea starts came out their hiding places. I used a net to catch all the FE in the water column. I siphoned out stressed sea stars. Did a 30G water change and use fresh active carbon. Corals and fish seem OK.

 

Will keep you posted.

what i did was use a power head to blow them off the rocks as they were dieing and keep them suspended. The went in overflow and into a sock filter which i cleaned out every 10 min to keep the toxin to a minimal. worked like a charm

I used a turkey baster to blow them off the rock and I have the socks also. I did not see much in the socks. Maybe I don't have that many FW.

good info to have that it will kill the stars like that... something else to think about if I ever get flatworms

Everything back to normal. Did not lose any coral or fish. Product works well.
