I know, and understand, the benefits of a proper test kit, from reading the forum. And I have a TF100 on the way.
But up until now, I've only had the 6-way test strips.
It seems to be okay with respect to seeing chlorine go up and down. But the CyA is crazy. If I were to go by the chart on the container, I have less than zero stabilizer! And yet, I just finished adding about 1lb to the pool last night.
Are the strips that bad that it won't even register?
What can I get rough estimates about with these crazy things?
