Testing results, need advice

[duraleigh]

mer1844,

The most interesting thing in your test results to me (thanks for posting good, complete numbers) is the 4.5 drop in FC over a 24 hour period. That's a little excessive in a normally operating pool....most folks drop 2-3ppm.

So, you probably have some organics in your pool and shocking is the way to get them out. Rather than "a 1lb bag of shock", it is important you understand that the idea is to get your chlorine to breakpoint...in your case about 15ppm..no less.

Calculate your pool gallons and add appropriately....probably closer to 2lbs of Cal Hypo but I don't know how many gallons are in your pool.

This should improve your water clarity (if it needs it) and get rid of the CC's in your pool.

Like Evan said, save the money and get rid of the nature2 cartridges.

All else is well.

Dumped in 3 gallons of 6% bleach this morning. That brought the FC up to 15.5 with a CC of 0.

For the Nat 2 issue; I'll use it the for the rest of this season because I replaced the cart only a few weeks ago. I won't use it next year. When I close the pool for winter, out she goes.

Thanks for the help.
