I can't maintain chlorine in my IG vinyl pool

TC 5
FC 10 (the hth kit does not test for free chlorine, so for this result I am using a 6 way test strip ...

This looks like a pretty good example of why we don't trust strips.
You will have a much easier go once you have the K-2006.

When things go bad, they really go bad. On Tuesday morning I found my pool pump not working, thought I would be spending $600 to $800 for a new one. Lucky, after some troubleshooting, I found that the pump motor had a bad capacitor, ordered it on Tuesday afternoon and received this morning. It has been replaced and my filtration system is back on line.

Now for some good news (I think), I performed a pool water test with my new Taylor K-2006 DPD Test kit and the results are below:

FC: 4
CC: .5
PH: 7.4
TA: 170
Total hardness: 330
CYA: 40

It appears like the pool has been holding chlorine, even though we have had a lot of rain in the area and my pump was out of service for several days. i have not added any chemicals and the water is clear. Are these levels within acceptable range?

Thanks to all for all of the great feedback,

Since your CYA is at 40 (which is a good level), you probably should just use bleach instead of dichlor.

Is this a liner pool or gunite?

Liner pool, I still have 8 new gallons of the hth liquid chlorinator, should I return and just get the bleach?

"liquid chlorinator" is just 10 - 12% bleach.
