Thanks for the reply, Steve, even though it's bad news.
Just tried the search function to locate the thread you were talking about, but it's not working right now. Can you give me an approximate date for the thread I'd be looking for? I do not remember seeing it.
Also, I know nothing about RO/DI stuff. Chris looks after that part of our reefing endeavor. He's busy tonight and tomorrow night, but I've told him basically what you've said. He will probably contact you via this thread or by PM to talk more about this issue, if that's okay with you.
Dang!!!! But, thanks
