Paul, man, you have the worst luck! I'm sorry to hear about this.

Some have theorized that a problem can occur when ammonia is present in the water. The ammonia leads to the growth of certain harmful types of bacteria, which can lead to respiratory infections. It is also theorized that forcing more oxygen in the water will help to combat both the ammonia and dangerous bacteria. Apparently, having a pond pump drop a stream of water, which creates turbulence, has been helpful for some people.

I'm merely passing this on. I don't know if I agree with it or not. Some people have claimed that doing this reduced or eliminated respiratory infections in their Spotteds. I tried to post a link to an entire thread on the topic, but when I previewed the post it had a "url block". I'm not sure why.

Good luck Paul!

Oh, and yes! Respiratory infections can be contagious!
