Well, some of the stuff may have returned through the return jets as I have some laying on the pool floor this morning. It doesn't seem to be as much as it was last night, so that's good news . I will vacuum again this evening and change out the filters again.

The CL tested this morning at 20-25 (had to dilute the HTH drop test kit), which means that it held the CL I put in last night. Right now I can only test free chlorine with a test strip unless I take water to the pool store. It came out much darker than 10. I did order Ben's kit over the weekend, but it'll be a little while until that arrives.

Another update coming this evening.
