Seriously, the only WRONG way to chlorinate is without testing or compensating when the test results tell you to.

But this is NOT what this clowns of the Health Depts are saying! They are saying : "use trichlor , as the most common chlorination product, which supplies both active chlorine and CYA, but be careful! When your CYA reaches 80 or more you're in trouble! Drain the pool!"

They should say: "Use trichlor only when you have a new pool, and once your CYA reaches 50 STOP USING IT!"
This should be the only logical recommendation regarding the use of trichlor products.

In both cases, the ongoing testing of CYA is a given.
