Source for DPD?

[calstar]

Where can I buy DPD in amounts larger the the typical 10gr containers? I can't believe there isn't a source for it in larger amounts.

thanks, Brian

It does go bad. Especially in damp environments. A 10gr container is typically sufficient for a full pool season.

I have seen it available in .25 lb size - that would be a huge amount - enough to fill 11+ of the 10g containers. Which is way too much for residential pool users.

I bought 2 10g containers when I first built my pool and by the time I needed to use the second one it was already going bad. So my advice follows Marty's above, just stick with the smaller containers and get a nice fresh one when you run out...

That makes sense. Asked because I just went through a slam for mustard algae and used 3/4+ fo the 10g with all the testing, obviously wont use that much in regular testing but thought I'd ask.

thanks again, Brian

SLAM should not be a regular process. I have never had to do one in my pool in nearly 5 years. The SWCG helps that immensely as every day, it add the chlorine I set it to add.
