You don't have to worry about CH being too low in a vinyl pool anyway. CH being too low is only important in plaster/gunnite pools to keep the water from leaching calcium out of the concrete. In a vinly pool, there is no calcium in the pool surface to protect.
If your CH gets too high, on the other hand, it can cause problems with milky water.

The people at the pool store are a real riot. I walked in and started looking at the liquid chlorine, the guy practically pulled me away from it and basically said I was a fool for
buying liquid chlorine vs. the cal-hypo because cal-hypo has double the amount of available chlorine than liquid. Of course the cal-hypo they sell is their brand at $7.99 a lb. and the liquid chlorine is $1.99 a gallon generic brand. Boy do they make their money on lies and uninformed consumers. Thanks again everyone for the education. It has been invaluable. :)
You mean he didn't then warn you that LC adds to your "TDS" levels and that's a bad thing (Total Dissolved Solids)? That's a typical scare tactic as well.
It's not just pools: this sort of marketing is EVERYWHERE. Here's a great article on how DeBeers 'created' the engagement diamond, using a rather common stone:Quote:

At least, deceptive pool marketing doesn't usually kill people!

Don't even get me started on DeBeers! (DeBeers was a Boer farmer whose land Cecil Rhodes exploited. All DeBeers got out of it was a famous name! Rhodes was the founder of DeBeers).
