First posting after Taylor 2006c testing

After reading the post about draining, sounds like exchanging is a safe alternative. @mknauss . I'll order a sump pump and do that soon. If you have any recommendations on a reasonable one, please let me know.

BTW...thanks for all the information. I'm trying to use the search feature as much as I can for my questions!

An exchange is good method. It helps if your pool water and fill water are different temperatures, by at least 10F, especially in a non-salt water pool.

@mknauss, Wonder if bobbie can put in a hose far away from drain, to start filling pool, while at same time draining it. I read of folks doing this, to keep the pool filled and lower cya.
They would open water to fill slower, watch level, if decreasing, would open fill more so level more less stays same through process.

Yes? No?

The Exchange process is well documented in Draining - Further Reading. It is a bit more involved than what you describe.

Here's the results from todays measurement. I got the speedstir delivered today; that's much nicer! I got the sump pump too but that will have to wait until tomorrow.

How did you measure a TA of 125? The test procedure results in values in a factor of 10. Review the test directions for that test.
Also, the TA increased over the last several tests. Have you been adding anything to do that? Fill water, baking soda, etc?

I was using the 10 ml sample. I'll do the test again.

And no...nothing added except we had a hellish day of rain two days ago.

@mknauss . OK..retested with the 25ml. Got a result of 110 TA

@mknauss ok...i think I've made some improvements and getting the hang of this. I am doing the exchange of water slowly but did get it down. Here's the latest numbers. One question...should I lower the pH to 7 to get the alkalinity down??

Looks good.
