It's not throwing errors that I'm forced to check, right now . . . so I'm not gonna. We're absolutely swamped with new users, plus I've got some major software upgrades in the works, so if it's not breaking something serious, I'm not getting out the digital backhoe, and hunting for it.

But, if you want to see if something breaks, try this: http://www.poolforum.com/pf2/showthr...6278-Pool-Info Once I have it fully tested, completing it will be required of all active posters. By the way, you will NOT be able to post in that section.

With respect to the Namco product, I followed the link and have no quick way to tell. I'm not going to dig right now, to see if it's the same. Where we (the PoolForum and I) are probably going is to ID a few sources of decent product that may be available locally PLUS links to Amazon product we know (or as close as I can get) is OK. There are just too many blends, labels, re-labels and name games for me to try to look at every stinking product and even annual revisions. Even when I have SwimmingPoolResearch fully operational, the MSDS and product sheets there will be the most recent available to us . . . but that does NOT guarantee that a company has not pulled a switcheroo on products, like cyanuric acid, that are not EPA regulated.

Bottom line: you're own your own with the Namco stuff. I haven't seen blended (diluted!) granular cyanuric acid yet, but I'm bet it's out there!
