Last week I bought my turtles some charales (Chirostoma) ((which they loved)), a new carrying tub (for the vet) and a small filter to compliment the other one I have. The thing is, that the day after I placed the filter and the fish, the water started becoming murky, and looking a bit like lemonade, the day after that the water was almost completely white, and a very disgusting smell (like rotting fish) started to appear. So I took my turtles and the filter out, and Changed all the water, and washed everything that was in the tank then I looked at the new filter and noticed that it had some media inside which contained zeolite and carbon, so I took those out and washed it again. When I finished and put my turtles back in the tank the same happened 2 days later so I took the new filter out completely, and repeated the process and so I haven't changed the water again since then because of the turtles, I feel it'll be bad to change it so often even under these circumstances.
My turtles have been doing fine though they eat, poop, swim and sleep as they normally would but I don't know what to do with the water.
I assume it might have something to do with the filter or the fish seing as they were the newest thing before this happened.
So if anyone could please tell me first of all why this is happening and second, what to do about it I would greatly appreciate it.
