Yeah, manufacturers do that sort of thing.

Remember, I told you that my impression of the Periodic guy is that (a) he's a real chemist and (b) he REALLY wants to make a financial killing.

However, if the CuLater does not get fouled with oils and such, based on the chemical mechanism described, it should work indefinitely. Obviously, that wouldn't fit well with the Periodic guys plans to get rich, so it's not real likely he's going to tell you that.

What's happened with these sorts of products in the past is that somebody discovered a perfectly valid niche product like Culator, but then discovers that a pool niche product will NEVER make him rich, so he tries to force EVERYONE into the niche. I suspect that's happening here.


Can I test for iron, copper, etc. myself, or should a have a pool store test it for me? Does the use of the Purple Stuff prevent getting accurate results?
+ We think HEPD interferes with most metal tests, but we're not sure. Taylor has not been really helpful on this.
+ Pool stores are almost certainly worse than the testing YOU can do.
