Flatworm nightmare
Did a treatment, flat worm treatment with flat morm exit changed 30 gallons of water , worms seems to be all dead will se effect on the rest of the tank. the dosing was restricted to the refugium because with my gate valves i can isolate both my refugiums and the main tank. So while i treated the refugium i could still pump and filter the main reef. When i restarted the refugium i just stopped the pumps to the main reef to give the carbon time to filter out the toxin for an hour before i resume the connection of both system.
I had previously taken my seahorses, my lionfish and my big inverts out of there, and put them in the huge overflow at the back of the main reef. Plenty of room and separators to isolate the lionfish. Now i'm just waiting to see the result and if other casulties will emerge. I had tried all possible natural ways, but they overtook the tank.
Sorry for the long wait not myself these days.
