Welcome to our forum.
Doesn't a 5 lb container of Lithium Hypochlorite alreadty last a long time? That seems like a bulk amount to me in the first place. How often are you having to buy this and much do you use?
See if your dealer will give you a case price for the items. If he cannot, PM me and I will see what I can do for you.
Yep, it lasts a bit. I'm almost half way through my 5 lb jar and I 've had my spa about 3 months. I just have the money and want to save $100+. If I pay $50 for a 5 lb jar and I can get a 25lb jar for $150 - [glow]do the math[/glow]. The return on that is much better than I can get on any investment (And that return is a guaranteed return)
Found this on Wiki http://wiki.answers.com/Q/Does_granular_chlorine_have_a_shelf_lifehttp://wiki.answers.com/Q/Does_chlorine_have_a_shelf_life
That answer says it has a 1 year shelf life. I think I'm currently getting around 4 months or so (will have pay closer attention) out of a 5lb jar. )
The real question is how fast it degrades after it has been opened and exposed to air. ... Just don't know how much or how fast.
