xingu I health issues

[j.r]

i have now medicated over a period (added medisin and some salt, waited 3days and did a w-c and added some more medisin, i have done this 3 times now over 9 days as i was told when i got the treatment) and it looks like it finally is on the retreat. i can still se a few spots on one of the bellycrawlers but thats about all, i added the last medisin yesterday so now i wait for a few days and will do some more w-c. will it be necesarry for me to add som active coal to my filter to get rid of remaning medisins in the water?? or will some w-c do the "trick"? this is not a verry "strong" medisin i have been told and it is supposed to be "kind" on the fish and plants..

and today it was back to square 1... i found my 2 biggest bellycrawlers dead today, so now i have lost 3 pikes.. 3 big nice pikes, im so fustrated i could cry.. it was looking so much better yesterday, everyone was out eating and looked so good. What i think i strange is that the 2 oscars doesnt seem to be affected at all. i have now medicated for about 1 week (added some medisin and waited 3days, then did a w-c and added some more medisin) i have now done this 3times over 9-12 days.. i have also added a little bit salt and turned up the heat. i will give this a week or so but if the fish keeps dying i have noe clue on what to do, so for now i can only wait and see and pray that the dying stops and the fish will get well.. i have taken out all plants and put them in a heavy salty water, and all driftwood is int the freezer untill tomorrow.. any good tips on anything more\else i can\could do??
