Cloudy water after adding quarantine meds

[Medtech011]

I have a 110 gallon freshwater tank.  I put the the quarantine trio meds in and the next day the water became cloudy.  Should I change the water and/or the filters, or wait? Worried because I lost 2 fish already.

Oh yeah also took out the carbon filters

Here is a link to another post that was dealing with the same problem. Hope it answers your question for you. Cory chimed in to help as well.

I have found that a Maracyn treatment does indeed kill some of my beneficial bacteria immediately. This has happened enough times that I can say that it's a consistent issue for me. The white cloudiness of a bacterial bloom comes the next day, and I have an ammonia and nitrite spike for the next two weeks.

Why some people and not others? My theory is that some of us have different nitrifying bacteria than others. Gram-positive vs. gram-negative and all that.

I know that Aquarium Co-Op testing hasn't seen this as a concern, but my water is very different than theirs. I live in Southern California, and my hardness and pH are always very, very high. Maybe it produces a different breed of nitrifying bacteria as a result?

Would love to see if someone has figured this out.

I would suspect no one has figured this yet as this would like involve fingerprinting the bacterial DNA using something like PCR. I don't think there is any hope for ID'ing the denitrifying bacteria the old fashioned way on agar.

But given PCR is now just a high school level lab, we may not be too far away from you and I and Brandy doing this. I've got a good PCR machine but I wouldn't know where to start with on making the primers.

We need a graduate student looking for a project.
