I read that antibiotics kill nitrifying bacteria, so if I do use it, I will take out both the carbon and the BioWheel. Then, how soon after treating should I put them back?
>>Forget all of this and let’s go with salinity. Mix up a small batch of saltwater (see if your LFS will sell you a couple of cups of salt mix, with directions for mixing to seawater density), or use kosher (non-iodized) salt. (I much prefer to use the seawater method, mixed to a specific gravity of 1.025.) Then, give all the fish a dip until they lose equilibrium. Along with this, I want you to add salt to the tank at a ratio of 1 teaspoon/gallon (you can go as high as 1 tablespoon quite easily) to be left in the tank for 4-6 weeks at least. This will do several things–the parasite cannot handle the difference of osmotic pressure which will kill the tomonts, salt is known to boost the effects of antibiotics (which might be necessary for secondary infection, but let’s wait and see first), and it relieves difference in osmotic pressure between the water and the fish’s body. These are all desirable. If you have live plants, you’ll need to remove them. >The medicine says to wait four day
