is it maracyn I and II dangerous for the filter?

[lunasmile]

I would like to know how dangerous is the use of maracyn I and II for the filter and for the cycle itself, i need to use this meds due to possible skinny disease. 4 of my clown loaches died, I have one more, it is not showing any problems, but I heard that skinny diseases was contagious, I am not sure if it is even worth it to put the maracyn, as prevention with my other fish. I have a 37 gallon tank with tiger barbs, plecos and catfish. please cab someone give me any info... thank you...

If used properly, there should be no significant damage to the bacterial colonies in the filter.

I have two canister filters plus two wet dry filters on my tank. One of the canisters has charcoal and the other has bio balls. If I am medicating and turn the one that has the charcoal off. Then turn it back on every other day for just enough time to change water in the canister. Do you think that would work?
Hope you understand what I am trying to say.
thank jerry

I wouldn't bother turning the one with carbon off. If the carbon is five days old or newer, I would remove the carbon.

If the carbon is 3 months to 6 months old then what? Is the carbon no good after five days?
thanks jerry

The instructions say to remove the carbon if it is five days old or less, because it would remove the drugs.
If your carbon is that old, it is probably not going to remove anything, including Maracyn 1 & 2.

If you follow directions, you should be okay. I have used Maracyn 1 &2 with biowheels and had no problems. Good luck!
