Richard,

Thanks for the feed back. I'm glad I was not the only one thinking along those lines. I was actually going to ask if you could get me a sample to see if I could run a test along the same lines you conducted. We'll just start calling CB The Reefkeepers Underwriters Laboratory (RUL). Ya'll are about the only LFS I know of that actually takes a hard look at new products rather then just accepting manufacturers claims at face value. I think this was unfortunately the cause that has led to the problems that were recently described in another thread with a similar product. I try to keep from using the term that refers to reptile fluids in conjunction with these products, but sometimes I think its justified. Water chemistry is an area that is probably most misunderstood among newbies to the hobby and I'm afraid a lot of manufacturers unfortunately take advantage of this.
